Architecture Quality Attributes¶

Executive Summary¶

Quality Attributes define the non-functional qualities Algosure architecture must support. They shape future technical decisions before implementation details are selected.

Why This Exists¶

Algosure is an enterprise procurement platform. It must be trustworthy, secure, explainable, scalable, maintainable, and reliable enough to support high-impact procurement work.

Owner¶

The owner is the Chief Product Officer and Enterprise Architect.

Business Value¶

Quality attributes make architecture measurable and reviewable. They prevent the platform from optimizing only for feature delivery while weakening trust, security, maintainability, or auditability.

Quality Attributes¶

Attribute	Architectural Meaning
Scalability	Architecture must support growth in tenants, users, documents, events, AI tasks, workflows, reports, and integrations.
Availability	Core customer workflows should remain available within defined service expectations.
Reliability	Workflows, events, approvals, and recommendations must behave predictably and recover safely.
Security	Identity, authorization, tenant isolation, secrets, data access, and audit must be designed in.
Performance	User interactions, reporting, search, AI orchestration, and workflow execution must meet practical business expectations.
Maintainability	Modular boundaries, conventions, tests, and documentation must make the system understandable and changeable.
Extensibility	New Domains, Practices, Digital Professionals, events, integrations, and workflows should be added without breaking existing ownership.
Testability	Architecture must support automated and manual validation of modules, contracts, workflows, security, AI outputs, and integrations.
Explainability	AI outputs, recommendations, and material decisions must expose rationale, evidence, assumptions, and confidence.
Compliance	Architecture must support compliance records, auditability, retention, approvals, and controlled evidence.
Tenant Isolation	Tenant context must be enforced across identity, data, events, memory, analytics, AI, and integrations.

Attribute Trade-Offs¶

Trade-Off	Governance Position
Speed vs auditability	Auditability wins for high-impact work.
Automation vs human approval	Human approval wins where impact thresholds require accountability.
Flexibility vs ownership clarity	Ownership clarity wins.
Microservices vs modular monolith	Modular monolith wins until scale and operational maturity justify extraction.
AI autonomy vs explainability	Explainability and approval gates win.
