Requirements marked met without verification evidence behind themA met status with no test, analysis, inspection, or review record behind it will not survive review. We surface every unbacked requirement b Compliance-matrix entries that cite superseded or moved documentsDocument revisions moved on but your compliance matrix still cites the old ones. We check every citation and flag each as current, supersede Certification-basis items missing from the compliance matrixA basis item your compliance matrix never picked up means nothing addresses it. We reconcile basis to matrix and hand you the uncovered item Derived requirements missing from the trace and safety assessmentDesign work spawns derived requirements, and some never enter the trace or feed the safety assessment. We list every orphan before your revi Environmental qualification that misses the categories the installation needsYour installation environment demands DO-160 categories the test report never covered. We compare levels line by line and list what is uncov Software lifecycle data that does not match the assigned software levelStructural coverage and independence shortfalls show up late in DO-178C programs. We check your data against the assigned level and name eac Airborne hardware data that does not match its design-assurance levelDO-254 data that trails its design-assurance level, often on verification or elemental analysis, invites findings.
