Architecture Roadmap¶

Executive Summary¶

The Architecture Roadmap defines the recommended architecture work sequence after the v0.2 foundation.

Why This Exists¶

The Architecture Foundation sets principles and governance. The next architecture waves must progressively define bounded contexts, events, data, security, AIOS, UX, integrations, and engineering readiness without jumping prematurely into implementation.

Owner¶

The owner is the Chief Product Officer and Enterprise Architect.

Business Value¶

The roadmap gives the team sequencing discipline and prevents scattered architecture work.

Recommended Architecture Waves¶

Sequence	Wave	Purpose
1	Bounded Context Architecture	Map Domains to technical module boundaries.
2	Modulith Architecture	Define modular monolith structure aligned to Spring Boot Modulith principles.
3	Event Architecture	Define event ownership, naming, versioning, idempotency, and consumption rules.
4	Data Architecture	Define data ownership, persistence responsibilities, reporting boundaries, audit, retention, and memory boundaries.
5	Security and Tenant Isolation Architecture	Define identity, authorization, tenant isolation, audit, and zero-trust architecture.
6	AI and AIOS Architecture	Define how Digital Professionals, AIOS, memory, explainability, and approvals align technically.
7	Workflow Architecture	Define process execution, approval gates, tasks, events, retries, and exception handling.
8	UX Architecture Alignment	Define how mobile and web experiences reflect the Digital Procurement Headquarters.
9	Integration Architecture	Define partner integration boundaries, contracts, events, and ownership rules.
10	Engineering Foundation	Translate architecture into engineering standards and implementation readiness.

v0.2 Exit Criteria¶

Architecture principles are approved.
Governance and decision process are established.
Quality attributes and constraints are documented.
Solution architecture direction is clear.
Next architecture waves are sequenced.
No implementation details are prematurely defined.
