Process assurance
Quality-assurance records review for avionics and equipment suppliers
A quality-assurance records review checks whether a supplier's QA records show the certification process was followed, not just planned. It is for avionics and equipment teams whose audit findings, process compliance records, and corrective actions need to hold together before submittal. The review covers the software and hardware quality assurance records, the audit and finding history, and the corrective-action trail. You receive an assessment of process-assurance coverage and a list of audits, findings, or corrective actions that are open, unevidenced, or inconsistent with the plans they audit against.
When this review is needed
- The package is going for review and the QA records have to show each planned audit actually ran.
- Findings from internal audits closed on paper but the corrective-action evidence behind them is missing.
- A process changed mid-program and no one confirmed the audits still check against the current plan.
- A reviewer wants to see that process assurance was independent of the engineering it audited.
The problem
Process assurance is what tells a reviewer the lifecycle was carried out the way the plans committed to. It is also the evidence that gets reconstructed last. Audits are scheduled and then skipped under pressure, findings get closed with a note instead of a record, and the corrective action lives in someone's memory. When the QA trail thins out, the package can show the work was done but not that it was done under control.
What gets reviewed
- The quality assurance plan and the audits and reviews it commits the program to
- Software and hardware quality assurance records against the activities they cover
- The audit history and whether each planned audit produced a recorded result
- Audit findings, their dispositions, and the evidence behind each closure
- The corrective-action trail from a finding to its verified resolution
- The independence of process assurance from the engineering it audits
What gets validated
- Each audit named in the QA plan has a recorded result, not just a schedule entry
- Audit results reference the plan revision and process they were checking against
- Every finding has a disposition and the evidence that supports its closure
- Corrective actions trace from the finding to a verified resolution
- QA records cover the lifecycle activities the assurance plan claims they do
- Process assurance is recorded as independent of the work it audits
- Open findings are visible rather than absorbed silently into a later baseline
Evidence normally required
- The quality assurance plan and the audit schedule it defines
- Software and hardware quality assurance records assembled so far
- The audit findings log with dispositions and closure notes
- The corrective-action records and any verification of resolution
- The lifecycle plans the audits were meant to check process against
Common discrepancies
- Audits listed in the plan with no recorded result behind them
- Findings closed with a disposition but no evidence of the corrective action
- Audit results that check against a plan revision the program has since replaced
- Corrective actions that close without verifying the fix held
- Process-assurance activity that is not recorded as independent of the engineering
- QA coverage gaps where a committed lifecycle activity was never audited
What is at stake
Records that cannot demonstrate the process was followed reopen the question of whether the technical evidence can be trusted at all. A thin QA trail can stall a review that the engineering itself would have passed, because the assurance the engineering depends on is not there to point to.
Move from findings to resolution
Identify gaps against the means of compliance.
How the work runs
Map the plan
List the audits and reviews the quality assurance plan commits to and confirm which produced a recorded result.
Check the findings
Trace each audit finding to its disposition and the corrective-action evidence behind its closure.
Test coverage
Confirm the QA records cover the committed lifecycle activities and check against current plan revisions.
Report the gaps
Deliver a coverage assessment and a prioritized list of open or unevidenced audits, findings, and actions.
What the buyer receives
- An assessment of process-assurance coverage against the QA plan
- A list of audits, findings, and corrective actions that are open or unevidenced
- A finding-to-closure trace showing where the corrective-action evidence stops
- A prioritized closure list ordered by the assurance gap each item leaves
Who uses the output
- Quality assurance leads reconstructing the process-assurance trail
- Certification leads confirming the lifecycle was carried out under control
- Engineering teams closing the corrective actions the findings left open
How the work fits into the transaction or program
The review checks the assurance layer that sits over the technical evidence. It pairs with a configuration-management evidence review when the question is which build the data describes, and with a compliance-checklist review when the team needs the objectives themselves checked rather than the process behind them.
Start with a single asset
Confirm requirements trace through verification.
Jurisdiction-specific considerations
FAA and EASA both expect process assurance to be evidenced, but the home for it differs. FAA programs lean on the quality assurance records the lifecycle plans commit to, while EASA Part-21 frames process assurance through the design organization's quality system. The audit content overlaps, so the review checks the records against the framework the program submits under rather than assuming the two are interchangeable.
Regulatory limits
Endeavor Elements checks the applicant's quality-assurance records for completeness, consistency, and traceability. It does not audit on the authority's behalf, make compliance findings, or issue any approval. The applicant's quality system and the authority keep their roles.
What this review does not cover
- Acting as the authority or making official compliance findings
- Running the supplier's internal audits or operating its quality system
- Generating the corrective-action evidence the records are missing
Specific to this review
- Process assurance is the evidence most often reconstructed last, which is why skipped audits and undocumented closures are the dominant finding.
- A finding closed without corrective-action evidence is indistinguishable from a finding ignored, so disposition notes alone do not survive review.
- Audits that check against a superseded plan revision give false assurance: the process they confirmed is no longer the process the program runs.
- Independence is a record, not an assumption; assurance that cannot show separation from the engineering it audits carries little weight in review.

Frequently asked questions
Does this replace our internal audit program?
No. The review checks whether the records your audit program produced are complete, evidenced, and consistent with the plans. The supplier keeps running its own quality system and closing its findings.
What if a finding closed but we cannot locate the corrective-action record?
That is a common result. The review flags closures without supporting evidence, traces where the record stops, and orders them so the team can rebuild the corrective-action trail before submittal.
