1. Executive Summary​

Constellation is a multi-tenant digital collaboration platform for enterprise commerce. It connects buyers, suppliers, and programme offices within a secure, unified environment for procurement, project coordination, documentation, training, and communication.

Enterprise supply chains face a fragmented landscape: organisations maintain their own procurement processes, supplier registries, and project management workflows. Cross-organisational collaboration remains hampered by incompatible systems, inconsistent data practices, and a lack of shared tooling.

Constellation addresses this gap by providing a modular, security-first platform that can operate in SaaS, private cloud, or on-premises environments, while enabling controlled collaboration across organisational boundaries. The platform is built with enterprise-grade security hardening (classification tiers, clearance-based access, audit chains) suitable for regulated industries including defence, aerospace, manufacturing, and government procurement.

The platform comprises seven integrated core modules:

  1. Supplier & Buyer Directory — Centralised identity, organisational profiles, and access management for all participating entities.
  2. Product & Services Catalog — AI-powered product information management with semantic search, taxonomy classification, CPQ pricing, supplier offer matching, and multi-channel syndication. Absorbs the Stella Catalog feature set.
  3. Procurement Module — End-to-end procurement workflows including RFQ generation, supplier matching, configure-price-quote (CPQ), offer scoring, and order management.
  4. Project Coordination & Quality Management — Multi-party project management with stage-gate monitoring, task tracking, progress dashboards, support ticket management, SLA tracking, and quality workflows.
  5. Documentation Management — Secure document repository with role-based access control, versioning, classification labelling, and audit trails.
  6. E-Learning Platform — Training, education, and certification management for compliance, product knowledge, and operational procedures.
  7. Communication & Notifications — Secure messaging, announcements, and event-driven notifications across all modules.

In addition to the seven core modules, this version of the specification introduces five extension modules that deepen the platform's value proposition for advanced use cases:

  1. Supplier Self-Service Portal — Streamlined onboarding, catalog management, and RFQ response tools for suppliers, particularly SMEs.
  2. Multi-Tier Supply Chain Visibility — Upstream and downstream supply chain mapping, component-level dependency tracing, and sub-tier risk indicators.
  3. Real-Time Inventory Availability — Optional supplier-exposed stock levels and production capacity data to enhance procurement sourcing decisions.
  4. Trade Compliance Engine — Automated export control screening, sanctions checking, and licence matching integrated across procurement and project workflows.
  5. Audit & Certification Tracker — Structured tracking of internal and external audits, corrective actions, and compliance certifications across the supply chain.

This document provides a functional brief for each core and extension module, an overview of the technical architecture, and a preliminary phasing roadmap. It is intended to serve as the foundation for a detailed business plan.

2. Platform Vision and Strategic Goals​

Vision Statement​

Constellation will become the trusted digital backbone for enterprise commerce collaboration — enabling buyers and suppliers to discover, procure, build, document, and learn together within a single secure environment, regardless of organisational boundaries or hosting infrastructure.

Strategic Goals​

Interoperability across enterprise supply chains. Constellation will normalise the interface between buying organisations and their supply chains, reducing friction in procurement and joint programmes. Rather than replacing existing systems, it will provide a common collaboration layer that integrates with existing ERP, PLM, and procurement platforms where needed.

Sovereignty and security by design. Every architectural decision will prioritise data sovereignty. Tenants must be able to control where their data resides, who can access it, and under what conditions. The platform will support SaaS, private cloud, and on-premises deployments, while still enabling controlled data sharing between tenants when authorised.

Modularity and incremental adoption. Organisations will be able to adopt Constellation module by module. A buyer may begin with the Supplier Directory and Procurement module, then expand into Project Coordination and Documentation Management as collaboration deepens. Each module must deliver standalone value while offering compounding benefits when used together.

Compliance and regulatory support. Constellation will be designed to support compliance with relevant regulatory frameworks, including GDPR, industry-specific classification schemes, and sector standards. Regulated-industry deployments (defence, government, aerospace) can enable additional compliance features (e.g., NATO STANAG, national classification, export controls) via tenant-level configuration.

Scalability from bilateral to multilateral. The platform must scale from a simple bilateral relationship between one buyer and one supplier, up to complex multilateral programmes involving multiple agencies, prime contractors, and sub-tier suppliers across organisational boundaries.

3. Stakeholder Overview​

Primary Stakeholder Types​

Buying Organisations (Demand Side) Procurement offices, agencies, and enterprise buyers that define requirements, issue procurement calls, manage contracts, and oversee programme execution. These include government agencies, large enterprises, and regulated-industry buyers operating under regulatory, classification, and sovereignty constraints.

Suppliers (Supply Side) Prime contractors, system integrators, sub-tier component manufacturers, technology providers, and service companies that respond to procurement calls, deliver products and services, and participate in manufacturing programmes. Suppliers range from multinational corporations to specialised SMEs.

Programme Administrators Programme offices that coordinate multi-party initiatives. They require oversight across multiple buyers and suppliers, consolidated reporting, and the ability to enforce programme-wide standards.

Platform Operators The organisations responsible for hosting, maintaining, and administering Constellation instances. Depending on the deployment model, this could be a central SaaS operator, an organisational IT department, or a regulated-sector IT directorate running an on-premises instance.

Roles Within the Platform​

Each stakeholder type will contain users operating in various roles. A non-exhaustive list of platform roles includes: Organisation Administrator, Procurement Officer, Supplier Manager, Project Manager, Quality Manager, Document Controller, Training Administrator, Compliance Officer, and End User. Role definitions and their associated permissions will be elaborated in the detailed design phase.

4. System Modules​

4.1 Supplier & Buyer Directory​

Purpose​

The Directory serves as the foundational identity and organisational data layer for the entire platform. Every entity — whether a buying organisation, prime contractor, or sub-tier supplier — must be registered in the Directory before it can participate in any other module. The Directory provides centralised user management, organisational profiles, qualification data, and access governance.

Key Functional Areas​

Organisation Registration and Profiles. Each participating organisation maintains a structured profile containing legal identity, registration numbers, points of contact, organisational hierarchy, areas of competence, certifications (e.g., ISO 9001, AS9100, AQAP, facility security clearances), and geographic presence. Profiles can be self-maintained by the organisation with validation workflows managed by platform or tenant administrators.

User Identity and Access Management. Individual users are registered under their parent organisation. The platform supports identity federation (SAML 2.0, OpenID Connect) to integrate with existing organisational identity providers, as well as local account management for organisations without a compatible IdP. Multi-factor authentication is mandatory. User accounts carry role assignments that are scoped to specific tenants, organisations, and modules.

Qualification and Compliance Tracking. Suppliers can upload and maintain evidence of their qualifications: certifications, audit results, export licences, facility security clearance status, and compliance declarations. Buyers can define qualification requirements and the Directory will flag suppliers whose credentials are expired, missing, or non-compliant.

Search and Discovery. Buyers can search the supplier base by capability domain (using configurable industry taxonomy standards such as UNSPSC, ETIM, NATO FSC, or CPV codes), geographic location, certification status, past performance ratings, and other structured attributes. Suppliers can similarly discover published buyer requirements and programme opportunities.

Organisational Hierarchy and Delegation. Large organisations can model their internal structure within the Directory — divisions, subsidiaries, business units — with delegated administration. This is critical for large enterprises that may have dozens of business units, each participating in different programmes with different clearance levels.

Key Workflows​

  • Organisation onboarding and profile approval
  • User provisioning, role assignment, and deprovisioning
  • Credential upload, validation, and expiry notification
  • Periodic re-qualification campaigns initiated by agencies
  • Federated identity linking for SSO integration

Data Entities​

Organisation, User, Role, Credential, Certification, Competence Domain, Security Clearance, Contact, Address, Organisational Unit.

Integration Points​

The Directory provides identity and authorisation context to every other module. It integrates with external identity providers via federation protocols and may synchronise organisational data with external supplier registries or industry databases.

4.2 Product & Services Catalog​

Purpose​

The Catalog provides a structured, searchable repository of products, services, systems, and capabilities offered by registered suppliers. It enables agencies to discover what is available on the market before initiating formal procurement, and it gives suppliers a persistent showcase for their offerings within the platform's commerce network.

Key Functional Areas​

Product and Service Listings. Suppliers create catalog entries for their offerings. Each entry includes a structured description, technical specifications, applicable standards, classification markings (where permitted), media (images, diagrams, data sheets), pricing guidance (indicative or upon request), lead time estimates, and links to relevant certifications from the Directory module.

Configurable Taxonomy. The Catalog uses a controlled taxonomy aligned with industry classification standards (e.g., UNSPSC, ETIM, NATO FSC, CPV codes, or a Constellation-specific taxonomy that maps to these standards). This ensures consistent categorisation and meaningful search results across suppliers from different organisations, even when product descriptions are in different languages.

Search and Filtering. Full-text search combined with faceted filtering by category, specification parameters, supplier country, certification status, classification level, and availability. The search engine supports synonym handling and multilingual queries to bridge terminology differences across participating organisations.

Comparison and Shortlisting. Buyers can select multiple catalog entries and generate side-by-side comparison views based on selected specification parameters. Shortlists can be saved and shared within the buyer's team, and can be carried forward into the Procurement module as the basis for an RFQ.

Catalog Governance. Tenant administrators and agencies can define catalog policies: which categories are visible to which tenants, whether pricing information is mandatory or optional, which classification levels are permitted in catalog entries, and whether listings require approval before publication.

Versioning and Lifecycle. Catalog entries have lifecycle states (draft, published, deprecated, withdrawn) and version history. When a supplier updates a product specification, previous versions remain accessible for reference in ongoing contracts or projects.

Key Workflows​

  • Supplier creates and publishes a catalog entry (with optional approval gate)
  • Agency searches, filters, and shortlists products for a potential requirement
  • Agency requests additional information from a supplier regarding a catalog entry
  • Supplier updates a listing and subscribers receive change notifications
  • Periodic catalog review and cleanup campaigns

Data Entities​

Catalog Entry, Product, Service, Specification Parameter, Category (Taxonomy Node), Media Attachment, Price Indication, Shortlist, Comparison Set, Catalog Policy.

Integration Points​

The Catalog reads supplier identity and qualification data from the Directory. Shortlists and product references flow into the Procurement module. Product references also appear in the Project Coordination module when specific products are assigned to manufacturing stages. Documentation linked to catalog entries is managed through the Documentation Management module.

4.3 Procurement Module​

Purpose​

The Procurement module manages the end-to-end acquisition lifecycle: from requirement definition and Request for Quotation (RFQ) through supplier matching, Configure-Price-Quote (CPQ), offer evaluation and scoring, to order placement and contract initiation. It is designed to support both standard commercial procurement and the more complex, regulated procurement processes typical of sectors such as defence, aerospace, and government, including restricted procedures, negotiated procedures, and framework agreements.

Key Functional Areas​

Requirement Definition. Procurement officers define requirements using structured templates. Requirements specify the needed products or services (linked to Catalog taxonomy), quantities, technical specifications, delivery timelines, qualification prerequisites, classification constraints, and evaluation criteria with weightings. Requirements can be created from scratch or derived from Catalog shortlists.

RFQ Generation and Distribution. Once a requirement is defined, the system generates a formal RFQ package. Distribution can be open (published to all qualified suppliers in the Directory), restricted (sent to a pre-qualified shortlist), or direct (single-source). The RFQ includes all requirement specifications, submission deadlines, required response format, and evaluation criteria (with or without disclosed weightings, depending on procurement policy).

Supplier Matching. An automated matching engine analyses the requirement against the Directory and Catalog data to suggest qualified suppliers. Matching considers competence domain alignment, geographic constraints, certification status, past performance scores, and current capacity indicators. Procurement officers review and refine the suggested list before distribution.

Configure-Price-Quote (CPQ). For configurable products or complex service offerings, the CPQ engine allows suppliers to build structured quotations. Suppliers select product configurations, specify options and variants, define pricing (unit, volume, lifecycle), and attach supporting documentation. The CPQ enforces consistency so that all supplier responses are comparable along the same parameter dimensions.

Offer Submission and Management. Suppliers submit their offers through the platform within the RFQ timeline. The system enforces submission deadlines, manages offer confidentiality (offers are sealed and inaccessible to the buyer until the evaluation phase opens), and handles offer amendments and clarification exchanges between buyer and supplier.

Evaluation and Scoring. Offers are evaluated against the published criteria. The platform supports multi-criteria scoring with configurable methodologies: weighted scoring matrices, best-value assessments, price-quality ratio calculations, and compliance checklists. Evaluation can be performed by individual evaluators with scores aggregated, or by evaluation panels with consensus workflows. Audit trails capture every scoring decision and justification.

Award and Order Management. Following evaluation, the procurement officer makes an award recommendation. The system generates award notifications, manages standstill periods (as required by applicable procurement regulations), handles debriefing requests from unsuccessful bidders, and initiates order or contract records. Orders can be one-time purchase orders, call-off orders against framework agreements, or phased delivery orders linked to project milestones.

Key Workflows​

  • End-to-end RFQ lifecycle: define → match → distribute → collect → evaluate → award → order
  • Clarification exchange (Q&A) during open RFQ period
  • Offer amendment before deadline
  • Multi-round negotiation for negotiated procedures
  • Framework agreement establishment and call-off ordering
  • Debriefing and protest management

Data Entities​

Requirement, RFQ, Supplier Match, Offer, CPQ Configuration, Evaluation Criterion, Score, Evaluation Panel, Award Decision, Order, Framework Agreement, Clarification, Amendment.

Integration Points​

The Procurement module is tightly coupled with the Directory (supplier qualifications and identity), the Catalog (product references and shortlists), and feeds into the Project Coordination module (when orders initiate manufacturing programmes). Award decisions and orders generate document records in the Documentation Management module. Support tickets may be raised within Project Coordination for post-order quality or delivery issues.

4.4 Project Coordination & Quality Management​

Purpose​

The Project Coordination module is a configurable project coordination engine that supports a wide range of industry verticals and use cases — from complex multi-year programmes with stage-gate oversight, to agile software delivery, service installations, procurement lifecycles, and custom workflows. Rather than prescribing a single methodology, the module provides a flexible structure of programmes, projects, stages, gates, tasks, and deliverables that tenants configure through project templates to match their operational context. This module also absorbs helpdesk and quality management capabilities — support tickets, SLA tracking, routing, root cause analysis, and quality scoring — operating as a unified project coordination and issue management hub.

Key Functional Areas​

Programme and Project Structure. Programmes are the top-level container, potentially spanning multiple countries and organisations. Each programme contains one or more projects, each project contains stages (phase gates), and each stage contains tasks and deliverables. This hierarchical structure adapts to many domains — for example, a manufacturing programme may follow concept → development → prototype → qualification → series production → in-service support, while a software delivery programme may follow discovery → design → build → test → release → operate.

Stage-Gate Workflows. Each project follows a configurable stage-gate model. Progression from one stage to the next requires that defined gate criteria are met: deliverables submitted, quality checks passed, reviews completed, and approvals obtained. Gates can be configured as automatic (all criteria met → proceed) or manual (gate review board decides). Gate reviews are auditable events.

Project Templates. The module ships with platform-provided templates for common verticals and supports tenant-created custom templates. Each template defines a stage pipeline (the ordered sequence of stages a project passes through), gate criteria (what must be satisfied to advance), custom statuses (domain-specific status labels beyond the universal set), and custom fields (additional data captured per project, stage, or task). Templates allow tenants to stand up new projects quickly while maintaining consistency within their organisation. The built-in template categories are:

  • Manufacturing — Stage-gate production workflows: concept, development, prototype, qualification, series production, in-service support. Suited for complex procurement and industrial programmes.
  • Service Delivery — Infrastructure installations, field services, and professional engagements: scoping, scheduling, deployment, commissioning, acceptance, warranty.
  • Software Development — SDLC with sprints or iterations: discovery, design, development, QA, staging, release. Supports agile cadences within the stage-gate structure.
  • Procurement — Requirement-to-contract lifecycle: needs identification, market research, solicitation, evaluation, negotiation, award, contract management.
  • General / Custom — A blank canvas with no pre-defined stages or gates. Tenants define the entire pipeline, criteria, statuses, and fields from scratch.

Universal Lifecycle. Regardless of the template in use, all project types follow the same conceptual lifecycle phases: Inquiry → Scope → Proposal → Approval → Execution → Quality → Delivery → Support. Templates map industry-specific terminology onto these universal phases — for example, a manufacturing template's "Qualification" stage maps to the Quality phase, while a software template's "QA" stage maps to the same phase. This universal lifecycle enables cross-vertical reporting, consistent audit trails, and a unified experience for organisations that operate across multiple domains simultaneously.

Task Management. Within each stage, tasks are assigned to specific organisations and individuals. Tasks have owners, deadlines, dependencies, priority levels, and status tracking. Task dependencies can cross organisational boundaries — for example, a lead contractor's integration task may depend on a partner's component delivery task. The system visualises dependencies and highlights critical path items.

Progress Monitoring and Dashboards. Real-time dashboards show programme-level, project-level, and stage-level progress. Key indicators include: percentage of tasks completed, milestone adherence (on time, delayed, at risk), resource utilisation, open risks and issues, and deliverable submission status. Dashboards are configurable by role — a programme director sees aggregate views, a project manager sees task-level detail.

Risk and Issue Management. Risks (potential future events) and issues (current problems) are tracked with severity classification, impact assessment, mitigation plans, ownership, and status. Risks and issues can be linked to specific tasks, stages, or programme-level concerns. Escalation workflows ensure that critical items reach decision-makers promptly.

Multi-Party Visibility and Boundaries. A defining characteristic of this module is that it operates across organisational boundaries while respecting information compartmentalisation. A programme office can see overall progress for all contributing parties, but each party sees only its own tasks and those of its immediate contractual partners. Data visibility rules are enforced through the platform's Row-Level Security model and configurable information-sharing agreements between parties.

Milestone Payments and Progress-Based Triggers. The system can link project milestones to contractual payment events and procurement order stages. When a milestone is formally completed and approved, the system can trigger notifications to financial and procurement teams or generate milestone completion certificates.

Key Workflows​

  • Programme setup: define structure, select or create a template, configure stages, gates, and participating organisations
  • Task assignment and acceptance across organisational boundaries
  • Progress reporting: periodic status updates from task owners
  • Gate review: evaluate gate criteria, conduct review, decide proceed/hold/rework
  • Risk/issue identification, assessment, mitigation tracking, and closure
  • Milestone completion certification and payment trigger notification
  • Programme-level reporting and audit

Data Entities​

Programme, Project, Project Template, Stage, Gate, Task, Dependency, Milestone, Risk, Issue, Progress Report, Gate Review, Deliverable, Resource Assignment, Dashboard Configuration, Custom Field Definition.

Integration Points​

Projects are initiated from awarded orders in the Procurement module or created directly from a template. Task deliverables are stored in the Documentation Management module. Quality issues discovered during stages are tracked as support tickets within the module's integrated issue management system. Training requirements identified during project execution link to the E-Learning module. Progress notifications flow through the Communication module.

4.5 Documentation Management​

Purpose​

Enterprise collaboration produces enormous volumes of documentation: specifications, drawings, test reports, certifications, contracts, correspondence, change requests, and operational manuals. The Documentation Management module provides a secure, structured repository with role-based access control, version management, classification labelling, audit trails, and document lifecycle governance. It must handle the particular sensitivity of regulated-industry documents, where access is determined not only by organisational role but also by security clearance level, organisational caveats, and programme-specific need-to-know.

Key Functional Areas​

Document Repository. A hierarchical folder and tagging structure allows documents to be organised by programme, project, organisation, document type, and classification level. Documents can be uploaded in any format, with special handling for common regulated-industry document types (technical data packages, CDRLs, standards-formatted documents).

Role-Based Access Control (RBAC). Access to documents is governed by a layered permission model. Permissions are determined by the intersection of the user's organisational role, their security clearance level, the document's classification marking, any organisational caveats or releasability restrictions, and programme-specific access lists. This multi-dimensional access model goes beyond simple RBAC — it implements attribute-based access control (ABAC) principles suited to regulated enterprise environments.

Classification and Labelling. Every document carries a classification label. The platform supports configurable classification schemes to accommodate the different systems used across participating organisations (e.g., internal confidentiality tiers, regulatory classification levels, or national equivalents). Labels are applied at upload, inherited from parent containers, or set via metadata rules. Reclassification workflows handle upgrades and downgrades with approval gates.

Versioning and Change Control. All documents are versioned. The system maintains a complete version history with change logs. For controlled documents (specifications, drawings, procedures), formal change control workflows require review and approval before a new version becomes the official current revision. Draft, in-review, approved, and superseded lifecycle states are tracked.

Search and Retrieval. Full-text search across document content and metadata, filtered by classification level, document type, date, author, programme, and other attributes. Search results respect access controls — users never see documents they are not authorised to view, and the system does not reveal even the existence of documents above their clearance level.

Audit Trail. Every access, download, upload, edit, share, and print event is logged with user identity, timestamp, action, and context. Audit logs are immutable and available to compliance officers and security administrators. This is essential for meeting security accreditation and regulatory compliance requirements.

Distribution and Transmittal. Formal document distribution workflows support transmittal letters, acknowledgement receipts, and read confirmations. Documents can be distributed to specific roles within specific organisations, with tracking to ensure that all intended recipients have accessed the document.

Key Workflows​

  • Document upload with classification assignment and metadata tagging
  • Review and approval workflow for controlled documents
  • Change request, review, and new version publication
  • Distribution with acknowledgement tracking
  • Periodic access review and re-certification of document permissions
  • Retention and disposal per classification-specific retention policies

Data Entities​

Document, Version, Folder, Tag, Classification Label, Access Control Entry, Distribution List, Transmittal Record, Audit Log Entry, Retention Policy, Change Request.

Integration Points​

The Documentation module is referenced by nearly every other module. Procurement documents (RFQs, offers, contracts, orders) are stored here. Project deliverables are submitted here. Catalog entries link to technical data sheets stored here. Support tickets within Project Coordination reference documents. E-Learning course materials are managed here. All document access events feed into the platform's central audit log.

4.6 Helpdesk & Quality Management (absorbed into Project Coordination)​

Note: This module's capabilities are delivered within the Project Coordination module (apps/project-tracker) rather than as a separate application. The feature descriptions below define the requirements that the project-tracker's issue management system must satisfy.

Purpose​

The Helpdesk module provides a structured system for managing quality issues, support requests, non-conformances, and operational incidents across the supply chain. It combines traditional IT service management (ITSM) concepts with industry-specific quality management workflows, and enforces SLA tracking to ensure accountability and timely resolution.

Key Functional Areas​

Ticket Management. Users raise tickets to report issues, request support, or log non-conformances. Tickets are categorised by type (quality issue, technical support, documentation request, complaint, change request, non-conformance report), priority, and affected module or programme. Tickets carry structured data fields specific to their type — for example, a non-conformance ticket includes part number, lot/serial number, inspection stage, defect description, and disposition recommendation.

Routing and Assignment. Tickets are automatically routed based on configurable rules: category, affected programme, source organisation, and priority determine which support team or quality manager receives the ticket. Manual reassignment and escalation are available. Cross-organisational routing is supported — a quality issue raised by a buyer against a supplier's deliverable is routed to the supplier's quality team with appropriate visibility controls.

SLA Management. Each ticket type and priority combination has a defined SLA with response time and resolution time targets. The system tracks SLA compliance in real-time, sends warnings as deadlines approach, and flags breaches. SLA definitions can be configured per tenant, per programme, or per contractual agreement between parties.

Workflow and Resolution. Tickets follow configurable workflows: triage → investigation → resolution → verification → closure. Quality-specific workflows include root cause analysis (with support for structured methods like 5-Why, Ishikawa), corrective action planning, corrective action implementation tracking, and effectiveness verification. The system supports linking related tickets to identify systemic issues.

Reporting and Analytics. Dashboards and reports show ticket volumes, SLA compliance rates, resolution times, recurring issue patterns, and supplier quality scores. Quality managers can generate periodic quality performance reports per supplier, per programme, or across the platform. These metrics feed into the Directory's supplier performance profile.

Knowledge Base. Resolved tickets and their solutions contribute to a searchable knowledge base. Common issues, workarounds, and standard resolutions are documented and linked to relevant categories, reducing resolution time for recurring problems.

Key Workflows​

  • Ticket creation (self-service or on behalf of another user)
  • Triage, categorisation, and priority assignment
  • Investigation and root cause analysis
  • Corrective action planning and implementation tracking
  • Resolution, verification, and closure
  • SLA breach escalation
  • Periodic quality review and supplier quality scoring

Data Entities​

Ticket, Category, Priority, SLA Definition, SLA Measurement, Workflow State, Root Cause Analysis, Corrective Action, Resolution, Knowledge Base Article, Quality Score, Escalation Rule.

Integration Points​

Quality issues may originate from the Project Coordination module (defects discovered during manufacturing stages), the Procurement module (post-delivery complaints), or the Documentation module (document quality issues). Resolution of quality issues may require documentation updates, project task modifications, or procurement actions (returns, replacements). Quality scores feed back into the Directory's supplier profile and influence supplier matching in Procurement.

4.7 E-Learning Platform​

Purpose​

Enterprise collaboration requires participants to maintain proficiency in a wide range of areas: regulatory compliance, security procedures, product-specific training, platform usage, and operational protocols. The E-Learning module provides a learning management system (LMS) integrated into the platform, enabling organisations to deliver, track, and certify training across the collaboration network.

Key Functional Areas​

Course Management. Training administrators create courses composed of modules, lessons, assessments, and practical exercises. Courses support multiple content types: text and document-based materials, video (hosted or embedded), interactive content (SCORM/xAPI compatible), quizzes, and practical assignment submissions. Courses can be categorised by topic, target audience, difficulty level, and certification type.

Learning Paths and Curricula. Related courses can be organised into learning paths (sequential or elective) that lead to a specific certification or qualification. Curricula can be defined at the programme level, organisational level, or platform level. For example, a programme might define a mandatory curriculum that all participating organisations' personnel must complete before accessing restricted programme data.

Enrolment and Access Control. Enrolment can be self-service (users browse the course catalog and enrol), assigned (administrators or managers enrol users based on role or programme requirements), or conditional (enrolment is triggered when a user is assigned to a programme or role that requires specific training). Access to course content respects the platform's classification and access control framework — training materials with classification markings are only visible to users with appropriate clearance.

Assessment and Certification. Courses include configurable assessments: multiple-choice quizzes, practical submissions reviewed by trainers, or formal examinations with time limits and proctoring indicators. Upon successful completion, the system issues digital certificates or qualification records. Certificates have expiry dates and the system tracks re-certification deadlines.

Compliance and Mandatory Training. Organisations and programmes can define mandatory training requirements tied to roles or activities. The system tracks compliance rates, sends reminders for incomplete or expiring training, and can enforce training prerequisites — for example, preventing a user from accessing a programme workspace until they have completed the required security briefing course.

Trainer and Content Management. Subject matter experts and trainers can author course content within the platform, conduct live sessions (with calendar integration), review assignment submissions, and monitor learner progress. Content can be shared across tenants (e.g., platform-wide compliance courses) or restricted to a specific organisation or programme.

Analytics and Reporting. Learning analytics track completion rates, assessment scores, time-to-completion, certification status, and compliance gaps. Reports are available at the individual, organisational, programme, and platform levels. Training data feeds into the Directory to enrich user and organisational profiles with qualification evidence.

Key Workflows​

  • Course creation, review, and publication
  • Learner enrolment (self-service, assigned, or conditional)
  • Course consumption and progress tracking
  • Assessment completion and grading
  • Certification issuance and re-certification tracking
  • Mandatory training compliance monitoring and enforcement
  • Training needs analysis based on programme or role requirements

Data Entities​

Course, Module, Lesson, Assessment, Question, Learning Path, Curriculum, Enrolment, Progress Record, Certificate, Certification Requirement, Trainer Profile, Content Package (SCORM/xAPI), Compliance Rule.

Integration Points​

The E-Learning module reads user and organisational data from the Directory. Training requirements may be triggered by role assignments in any module or by programme onboarding in the Project Coordination module. Certificates and qualification records are stored in the Documentation Management module and reflected in the Directory's user profile. Training completion can be a prerequisite enforced by access control rules across all modules. Course announcements and reminders flow through the Communication module.

4.8 Communication & Notifications​

Purpose​

Effective collaboration requires reliable, secure, and context-aware communication. The Communication module provides messaging, announcements, and event-driven notifications across the platform. Unlike general-purpose communication tools, it is designed to operate within the platform's classification and access control framework, ensuring that sensitive communications remain within authorised boundaries.

Key Functional Areas​

Direct and Group Messaging. Users can exchange messages one-to-one or within groups. Messaging is integrated with the platform's organisational and programme context — users can message within a programme team, a procurement working group, or a project stage team. Message threads can be linked to specific entities (a procurement requirement, a project task, a helpdesk ticket) for contextual traceability. Messages respect the platform's classification framework: a message channel associated with a classified programme enforces that only cleared participants can join.

Announcements and Broadcasts. Administrators, programme managers, and platform operators can publish announcements targeted at specific audiences: all platform users, all users in a tenant, all participants in a programme, or all members of a specific organisation. Announcements support scheduling, acknowledgement tracking, and priority levels.

Event-Driven Notifications. The platform generates notifications in response to events across all modules. Examples include: new RFQ published, offer deadline approaching, task assigned, gate review scheduled, document requiring approval, SLA breach, training due, certification expiring, and helpdesk ticket status change. Users configure notification preferences: in-platform notification centre, email digest, or both. Notification rules are configurable per role and per module.

Notification Centre. A centralised notification centre aggregates all notifications for a user, with filtering, read/unread status, and direct navigation to the source entity. The notification centre provides a single entry point for users to understand what requires their attention across all platform modules.

Secure Communication Compliance. All messages and notifications are logged for audit purposes. The platform enforces communication boundaries: users cannot inadvertently send classified information outside the appropriate channels. Message retention policies are configurable per tenant and comply with organisational records management requirements.

Integration with External Communication. For organisations that require it, the platform supports controlled integration with external communication systems: email relay for notifications (with content sanitisation to prevent classification spillage), and webhook-based integration with external collaboration tools used within individual organisations. External integrations are configurable per tenant and subject to security policy approval.

Key Workflows​

  • Direct message exchange within programme or project context
  • Announcement creation, targeting, scheduling, and acknowledgement tracking
  • Notification preference configuration by user
  • Notification delivery and read tracking
  • Communication audit and compliance review

Data Entities​

Message, Thread, Channel, Announcement, Notification, Notification Rule, Notification Preference, Delivery Record, Audit Log Entry, Communication Policy.

Integration Points​

The Communication module receives events from all other modules to generate notifications. It uses the Directory for recipient resolution and access control. Message attachments are governed by the Documentation Management module's classification and access rules.

4.9 Supplier Self-Service Portal​

Purpose: Enable suppliers — particularly SMEs with limited IT resources — to independently manage their presence on the platform. Rather than relying on buyer administrators, suppliers can onboard, maintain catalog entries, upload qualification data, and respond to RFQs through a purpose-built, simplified workflow. This reduces friction and accelerates the time from registration to active participation.

Key Functional Areas:

Bulk Import Tools. Suppliers import product listings and CPQ configurations in bulk (Excel, XML). The import engine validates data completeness, flags errors, and provides a preview before committing.

Offer Tracking Dashboard. Consolidated view of active RFQs, response deadlines, submission status, and award outcomes across all tenants and programmes.

Certification Uploads with Expiry Alerts. Upload certifications with metadata including issue/expiry dates. Automated alerts before expiry prompt renewal.

Auto-Validation for Data Completeness. Validates profiles and catalog entries against configurable completeness rules. Missing fields or expired documents are flagged with guidance.

Key Workflows:

  • Supplier self-registration and profile completion
  • Bulk product and CPQ data import with validation
  • Certification upload with automated expiry tracking
  • RFQ response preparation and submission via portal

4.10 Multi-Tier Supply Chain Visibility​

Purpose: Provide visibility into lower-tier suppliers and subcontractors contributing to programmes. Complex manufacturing involves deep supply chains with multiple tiers, and buying organisations currently have limited visibility beyond direct partners, creating blind spots for risks.

Key Functional Areas:

Supply Chain Graph. Interactive graph showing upstream/downstream supplier relationships per programme/product. Nodes represent organisations, edges represent supply relationships with criticality designations and risk indicators.

Component-Level Dependency Tracing. Traces which components come from which suppliers at each tier. Identifies single-source dependencies, concentration risks, and substitution options. Data populated from BOMs, procurement data, or manual input.

Lead Time Aggregation Across Tiers. Calculates aggregate lead times by tracing the critical path through supply chain tiers for more realistic scheduling.

Sub-Tier Qualification and Risk Indicators. Risk indicators computed per node based on qualification status, quality scores, delivery performance, financial stability, and geopolitical risk factors.

Key Workflows:

  • Supply chain mapping for a programme or product
  • Component dependency analysis and single-source identification
  • Lead time simulation and critical path analysis
  • Sub-tier risk assessment and alert configuration
  • Periodic supply chain health review and reporting

Data Entities: Supply Chain Graph, Supply Relationship, Component, Bill of Materials (BOM), Dependency Record, Lead Time Estimate, Risk Indicator, Risk Threshold, Supply Chain Alert.

Integration Points: Extends Project Coordination and Directory modules. Risk indicators draw on Project Coordination quality data. Dependency data linked to catalog entries and procurement orders. Alerts via Communication module.

4.11 Real-Time Inventory Availability (Optional)​

Purpose: Allow suppliers to expose available stock or production capacity. Transforms the Catalog from a static showcase into a dynamic sourcing tool for time-sensitive procurement.

Key Functional Areas:

Inventory Visibility Toggle. Each catalog entry includes optional inventory visibility. Displays real-time availability: in stock, limited, made to order, or out of stock.

Data Input Methods. Updated via supplier portal (manual), API integration with ERP (automated), or periodic bulk uploads (semi-automated).

Estimated Restock and Lead Time Fields. Suppliers provide estimated restock dates, production lead times, and minimum order quantities for out-of-stock items.

Integration Points: Enhances Catalog and Procurement modules with real-time sourcing insights. May inform Supply Chain Visibility lead time calculations. Managed through Supplier Self-Service Portal for manual updates.

4.12 Trade Compliance Engine​

Purpose: Automate validation of export controls, licences, and sanctioned entity restrictions. Non-compliance carries severe legal, financial, and reputational consequences in cross-border commerce.

Key Functional Areas:

Export Licence Matching. Matches products, destination countries, and end-use against export control regimes (EU Dual-Use Regulation, Wassenaar Arrangement, national controls, ITAR flags).

Sanctioned Entity Screening. All transaction parties screened against consolidated sanctions lists (EU, UN, national). Screening at initiation, workflow gates, and periodically. Matches trigger compliance review.

Region-Based Compliance Rules. Configurable rules by source/destination country, product category, classification level. Encodes embargoes, restricted destinations, licensing thresholds, exemptions.

Pre-Shipment Checks. Automated checks before physical transfer: licence validity, end-user certificates, sanctions re-screening, quantity verification against licence allowances.

Key Workflows:

  • Compliance screening at RFQ distribution and offer evaluation
  • Export licence determination for cross-border transactions
  • Sanctioned entity screening at onboarding and transaction initiation
  • Pre-shipment compliance check at project milestones
  • Compliance exception review and approval
  • Periodic re-screening of existing relationships

Data Entities: Compliance Rule, Export Control Classification, Licence Requirement, Licence Record, Sanctions List, Screening Result, Compliance Review, Pre-Shipment Check, End-User Certificate, Compliance Exception.

Integration Points: Tightly coupled with Directory (entity screening), Procurement (transaction compliance), Project Coordination (pre-shipment checks), and Documentation (licence records). Alerts via Communication module.

4.13 Audit & Certification Tracker​

Purpose: Track internal and external audits, corrective actions, and compliance certifications across the supply chain.

Key Functional Areas:

Audit Event Scheduling and Logs. Schedule and track audits by type (internal, external, customer, regulatory), scope, date, auditors. Calendar view of upcoming/overdue audits. Immutable audit logs.

Findings and Corrective Action Management. Record findings with severity (major/minor non-conformity, observation, improvement opportunity), evidence, root cause analysis. Corrective actions with owner, deadline, status, and effectiveness verification.

Certification Status Dashboards. Consolidated view of certification status across suppliers/programmes. Displays certificate types (ISO 9001, AQAP, AS9100, security clearances), dates, audit history, gaps.

Integration with Project Coordination for Non-Conformities. Audit findings can generate support tickets within Project Coordination, ensuring consistent corrective action tracking across audit and operational quality workflows.

Key Workflows:

  • Audit scheduling and notification
  • Audit execution logging and finding recording

5. Technical Architecture Overview​

Architectural Principles​

Modularity. The platform is composed of independently deployable services, one per functional module. Each module exposes well-defined APIs and can be deployed, scaled, and updated independently. This supports incremental adoption and reduces the blast radius of failures or updates.

Multi-Tenancy. The platform is designed from the ground up for multi-tenancy. A single deployment can serve multiple independent tenants (e.g., national agencies, multinational programme offices) with strict data isolation. Tenancy is a first-class architectural concept, not an afterthought.

Security-First Design. Security is not a layer applied on top — it is embedded in every component. Authentication, authorisation, encryption, audit logging, and classification enforcement are cross-cutting concerns addressed at the platform level, not left to individual modules.

API-First Design. All functionality is exposed via RESTful APIs (or gRPC where performance demands it). The web interface, mobile clients, and third-party integrations all consume the same APIs. This ensures consistency and enables extensibility.

High-Level Components​

Presentation Layer. A responsive web application built with a modern frontend framework, providing the primary user interface. The UI is modular, reflecting the platform's module structure, and supports localisation for multiple languages. A mobile-responsive design ensures usability on tablets for field and factory-floor use.

API Gateway. A central entry point that handles authentication token validation, rate limiting, request routing, and API versioning. The gateway enforces tenant context on every request, ensuring that downstream services always operate within the correct tenant boundary.

Module Services. Each functional module is implemented as one or more backend services. Services are stateless where possible, store data in the shared database layer, and communicate with each other through well-defined internal APIs or an event bus.

Event Bus. An asynchronous messaging layer that enables event-driven communication between modules. When a significant event occurs (order placed, task completed, document approved), the originating module publishes an event. Other modules subscribe to relevant events and react accordingly. This decouples modules and enables extensibility — new modules can subscribe to existing events without modifying the originating module.

Database Layer. A relational database (PostgreSQL recommended for its mature Row-Level Security capabilities) serves as the primary data store. All tenant data resides in a shared database with schema-level and row-level tenant isolation enforced by the database engine itself (see Security Model below). A search engine (e.g., Elasticsearch) provides full-text search across Catalog, Documentation, and other searchable content.

File Storage. Documents, media, and other binary assets are stored in an object storage layer (compatible with S3 API for cloud deployments, or a local storage backend for on-premises deployments). File storage is encrypted at rest and access is mediated through the Documentation Management module's access control layer.

Identity and Access Management (IAM). A dedicated IAM service handles user authentication, session management, federation with external identity providers, role-based and attribute-based access control policy evaluation, and security token issuance. The IAM service is the single source of truth for "who is this user, and what are they allowed to do."

Audit and Logging. A centralised audit service collects security-relevant events from all modules: authentication events, access decisions, data modifications, document accesses, and administrative actions. Audit logs are stored in an append-only, tamper-evident log store. A monitoring and alerting layer detects anomalies and security-relevant patterns.

6. Security Model & Compliance​

Multi-Tenancy and Data Isolation​

Constellation's multi-tenancy model is based on Row-Level Security (RLS) implemented at the database level. Every data row carries a tenant identifier, and database-level security policies ensure that queries automatically filter to only the rows belonging to the requesting tenant. This provides defence-in-depth: even if an application-level bug bypasses tenant filtering, the database engine itself enforces isolation.

Tenant boundaries are strict by default. Data sharing between tenants (e.g., when two agencies collaborate on a programme) is enabled through explicit, auditable data-sharing agreements configured by tenant administrators. Shared data is not copied — instead, controlled cross-tenant read access is granted to specific data sets with specific permissions.

Access Control Model​

The platform implements a hybrid RBAC/ABAC model. Roles define coarse-grained permissions (e.g., Procurement Officer can create RFQs), while attributes provide fine-grained contextual access decisions (e.g., this user can view this document because they have SECRET clearance, are assigned to Programme X, and hold the Document Reviewer role within that programme).

Access control policies are evaluated centrally by the IAM service and enforced at both the API layer and the database layer (via RLS policies). This defence-in-depth approach ensures that data cannot be accessed through any path without proper authorisation.

Classification and Information Handling​

The platform supports configurable classification schemes. Each tenant can define its classification levels (mapping to national schemes), and the platform enforces handling rules appropriate to each level. At a minimum, this includes access restrictions (only users with appropriate clearance can access classified data), audit logging (all access to classified data is logged), and distribution controls (classified data cannot be shared outside defined boundaries without explicit approval).

The platform itself is designed to operate at a maximum classification level determined by its accreditation. Data above this level must not be stored on the platform. Classification enforcement is applied at the document level, the message level, and the metadata level.

Encryption​

All data in transit is encrypted using TLS 1.3. Data at rest is encrypted using AES-256. Encryption keys are managed through a dedicated key management service (KMS) that supports hardware security modules (HSMs) for environments requiring FIPS 140-2 or equivalent certification. Per-tenant encryption keys enable cryptographic tenant isolation where required.

Compliance Frameworks​

Constellation is designed to support compliance with:

  • GDPR — Personal data processing is minimised, purposes are defined, consent is managed where applicable, and data subject rights are supported.
  • ISO 27001 / ISO 27701 — The platform's security controls and privacy management are aligned with these standards to support organisational certification.
  • Sector-Specific Regulatory Frameworks — The platform's architecture supports the documentation and evidence requirements for security accreditation under various frameworks. Examples include defence procurement directives (e.g., EU 2009/81/EC), national security accreditation (e.g., BSI, ANSSI), and NATO standards (STANAG document formats, classification markings). These are enabled via tenant-level configuration rather than hard-coded into the platform.
  • Industry Standards — Where applicable, the platform supports configurable classification markings, regulated document formats, and interoperability standards relevant to the tenant's sector.

7. Deployment Models​

Constellation supports three deployment models to accommodate the diverse infrastructure requirements of enterprise commerce.

Private Cloud (SaaS-like)​

A centrally operated instance hosted in a sovereign or compliant cloud environment (e.g., OVHcloud Sovereign Cloud, T-Systems Sovereign Cloud, AWS GovCloud, or organisational cloud infrastructure). Multiple tenants share the infrastructure, with isolation enforced through the platform's multi-tenancy model. This model offers the lowest operational burden for participating organisations and the fastest path to deployment. It is suitable for data up to a classification level determined by the cloud environment's accreditation.

Dedicated Private Cloud​

An instance deployed in a dedicated cloud environment operated exclusively for one tenant or a small group of tenants. This model provides stronger isolation (dedicated compute, storage, and network resources) while still leveraging cloud infrastructure for scalability and manageability. It is suitable for organisations or programmes with higher security requirements or regulatory constraints that prevent sharing infrastructure.

On-Premises​

A fully on-premises deployment within an organisation's own data centre or secure facility. This model provides maximum control over the infrastructure and is required for environments handling data at higher classification levels or operating in air-gapped networks. The platform's architecture must support this deployment mode without modification to the application logic — infrastructure dependencies (database, object storage, message broker, identity provider) must have on-premises alternatives.

Hybrid and Federated Deployment​

In advanced scenarios, multiple Constellation instances (cloud and on-premises) may operate in a federated model. A programme office might run a cloud instance for programme-level coordination, while individual national agencies run on-premises instances for classified national data. Controlled data exchange between instances is facilitated through a federation protocol with well-defined data sharing boundaries and transformation rules. This federated model is a longer-term architectural goal and would be defined in detail during later design phases.

8. Cross-Module Integration Map​

The following summarises how the twelve modules (seven core and five extension) interact, forming a cohesive platform rather than a collection of isolated tools. Note that Helpdesk & Quality Management capabilities are delivered within the Project Coordination module rather than as a separate module.

The event bus architecture ensures that new integration points can be added without modifying existing modules. Each module publishes events to standardised topics, and any module (or future extension) can subscribe.

9. Indicative Phasing Roadmap​

The following phasing is indicative and will be refined during business plan development. It reflects a recommended order of implementation based on dependency analysis and value delivery.

Phase 1 — Foundation (Months 1–9)​

Core platform infrastructure: IAM service, API gateway, database with RLS, event bus, file storage, audit logging, frontend shell. Supplier & Buyer Directory: Organisation registration, user management, identity federation, qualification tracking. Documentation Management: Document repository, RBAC, classification labelling, versioning, search, audit trail. Communication & Notifications: Notification centre, event-driven notifications, direct messaging.

Rationale: These modules provide the foundational identity, security, document, and communication infrastructure upon which all other modules depend.

Phase 2 — Procurement (Months 7–15)​

Product & Services Catalog: Listing management, taxonomy, search, shortlisting. Procurement Module: Requirement definition, RFQ lifecycle, supplier matching, CPQ, offer evaluation, order management.

Rationale: Procurement is the primary value proposition for buying organisations. With the Directory and Documentation in place, the Catalog and Procurement modules can deliver immediate, tangible value.

Phase 3 — Programme Execution (Months 13–21)​

Project Coordination & Quality Management (including Quality Management): Programme/project structure, stage-gate workflows, task management, progress monitoring, risk/issue management, ticket management, SLA tracking, quality workflows, knowledge base.

Rationale: Once procurement is operational and orders are flowing, the need for project coordination and quality management follows naturally. Helpdesk and quality capabilities are delivered as part of the Project Coordination module.

Phase 4 — Capability Maturity (Months 19–27)​

E-Learning Platform: Course management, learning paths, certification, compliance tracking. Advanced features across all modules: Analytics dashboards, federation between instances, advanced reporting, mobile optimisation, API marketplace for third-party integrations.

Rationale: The E-Learning module, while valuable, has fewer dependencies on other modules and can be introduced once the core collaboration workflows are established.

Note: Phases overlap intentionally to allow parallel workstreams and earlier delivery of high-value capabilities.

Phase 5 — Advanced Capabilities (Months 25–36)​

Supplier Self-Service Portal: Bulk import tools, offer tracking dashboard, certification management, data completeness validation. Multi-Tier Supply Chain Visibility: Supply chain graph, component dependency tracing, lead time aggregation, sub-tier risk indicators. Real-Time Inventory Availability: Inventory visibility toggles, API-based and manual stock updates, sourcing insights integration. Trade Compliance Engine: Export licence matching, sanctioned entity screening, region-based compliance rules, pre-shipment checks. Audit & Certification Tracker: Audit scheduling/logging, findings and corrective action management, certification dashboards, Project Coordination integration.

Rationale: Extension modules address advanced requirements that become critical once the core platform is established. Trade compliance and supply chain visibility are particularly important as cross-border collaboration deepens.

Note: Extension modules (Phase 5) may be reprioritised based on customer demand and regulatory developments.
