From software change to release evidence
An anonymized illustration based on my work with regulated medical software. Not a reproduction of an employer project or internal documentation.
At Aidoc, from August 2022 to October 2026, I worked as Senior Software QA & RA Compliance Specialist on verification, change management, and release documentation for regulated medical software.
A new software version is ready, and the old tests passed. Is that enough?
The answer depends on what changed, which risks and dependencies are affected, and whether the old test conditions still match.
Keep the context with the evidence
A result is useful in the context of its requirements, configuration, and scope. That means reviewing change impacts, requirements and design documentation, verification and validation protocols, results and reports, and requirements traceability. My approach draws on the lifecycle perspective of IEC 62304 and the risk focus of ISO 14971.
Reuse is a decision
A passing result belongs to a particular scope and configuration. If those still apply, repeating the test may add little. The reasoning for reuse needs to be documented. Where behavior, dependencies, or relevant risks have changed, targeted verification, regression testing, or further investigation can address the gaps.
Illustrative decision sketch
Does the evidence still fit?
Read the diagram as text
Assess the impact and risk of a software change. Does existing evidence cover the changed configuration? If yes, reuse relevant evidence with documented justification, then review all relevant evidence and outstanding issues for release readiness. If no, specify and perform targeted verification or regression testing to address gaps. If an issue or evidence gap is found, investigate and address it, then reassess impact and risk and repeat the evidence assessment. Proceed to release-readiness assessment only after evaluating the relevant evidence and outstanding issues. Test results alone do not authorize release.
A late reply, worked through
Fictional example illustrating a risk-based verification approach. The scenario, findings, correction, and conclusion below are invented for explanation.
- Change
- A maintenance release extends a communication timeout and changes retry behavior for a status update sent to an external system.
- Impact assessment
- A late reply can now arrive after a retry starts. The assessment covers missed, delayed, or duplicate updates and recovery. Tests of unaffected behavior remain candidates for reuse after checking their scope and configuration.
- Verification & findings
- In this fictional scenario, ordinary timeout and recovery checks pass, but no test covers a reply arriving just after a retry starts. An added check reveals that the same update can be processed twice.
- Address & reassess
- The duplicate-handling logic is corrected. The late-reply test and related timeout, retry, duplicate-prevention, and recovery checks are rerun and pass. Existing evidence is rechecked against the updated configuration.
- Illustrative decision
- The gap is closed and the evidence supports release readiness for this change. That conclusion follows a review of risks, traceability, results, and outstanding issues, not one passing test. A release remains a team decision.
A decision the team can review
In my work, these questions involved engineering, Product, DevOps, QA/RA, and risk-management stakeholders. Different perspectives helped clarify what a change affected and which questions remained open. Verification results informed a shared release-readiness assessment; they were not, by themselves, a decision to release.
The useful result is a clear account of which evidence still applies, which gaps have been checked, and what remains unresolved. That is what effective verification comes down to: understanding which evidence is needed, why, and what it actually demonstrates.
Have a question about software testing or release evidence? I’d be happy to hear from you.
