Capture
Record the requirement with its source, rationale, hierarchy, and acceptance intent.
Product system
One controlled path from intent to evidence
SDD connects requirements, specifications, accountable action, tests, and proof in a project model that can be reviewed at every stage.
Decisions retain their source. Execution stays inside approved boundaries. Verification feeds the next controlled decision.
Governed workflow
Move forward without losing the reason why
Each stage changes the form of the work while preserving its business context, ownership, and evidence obligations.
Specify
Derive precise behavior, boundaries, acceptance criteria, and connected risks.
Execute
Coordinate issues, reviews, documents, agents, and implementation against approved scope.
Prove
Run tests, preserve results, expose coverage, and generate audit-ready evidence.
Persistent traceability
One chain, visible from either direction
Start from business intent to inspect delivery, or start from evidence to prove exactly which approved need it verifies.

Complete context
Enterprise systems, documents, project knowledge, decisions, and conversations stay connected.
Explicit authority
Versions, approval gates, ownership, and change requests define when work may advance.
Objective feedback
Coverage gaps, test findings, and risks return as governed input to the next decision.
