Intent
Define the outcome, users, constraints, critical behaviours, and evidence required for acceptance.
Engineering Standards / Quality Assurance
Quality is designed before it is tested.
A test result has meaning only when the expected behaviour, risk, environment, and acceptance authority are already clear.
Assurance model
Four connected decisions.
Design
Review architecture, interfaces, data movement, failure modes, and operational responsibilities before implementation accelerates.
Verification
Use risk-led test layers and traceable evidence instead of relying on a final demonstration.
Release
Make readiness a deliberate decision covering product behaviour, security, operations, support, and rollback.
Verification depth
Test where failure becomes visible.
Verification is selected from system risk. It may include code-level behaviour, service contracts, data integrity, end-to-end journeys, load, recovery, usability, and operational exercises.

Operational recovery
Release evidence
A release is a risk decision.
Acceptance criteria have current evidence
Known defects have an owner and disposition
Security and operational checks are complete
Rollback and support responsibilities are understood
