LEARN. PRACTICE. GROW.Concept and mechanism
Traceability in use requires maintenance. When a requirement changes, identify affected models, interfaces, tests, and documentation and compare the proposal with the baseline. Updating the main text alone is insufficient. Preserve request origin, impacts, dependencies, risks, and decision. Communicate status to the project manager and stakeholders at the detail needed for action. A report containing only completion percentage can hide a blocked critical requirement. Show missing conditions, owners, and consequences for the next decision. Avoid turning an administrative state into technical proof: a closed ticket does not guarantee the delivered version was accepted by the right owner.
Guided application
In one example, there are 40 mandatory requirements; 30 have linked tests, but only 24 have approved results for the current version. Link coverage is 75%; approved-evidence coverage is 60%. Neither measure alone establishes production readiness without considering the criticality of the remainder. If a change alters message format, an old test capture may no longer suffice even with the same identifier. Reassess the link and plan necessary confirmation. For an urgent request, use the applicable change process and make scope, schedule, and support effects visible. Urgency may justify an authorized accelerated route, but does not turn a chat message into a complete decision.
30/40 = 75% link coverage; 24/40 = 60% approved evidence.
Common pitfalls
Closed ticket treated as acceptance; linked test treated as approved; urgency treated as exemption from analysis.
