Notes from the audit table.
Short, specific pieces on certification evidence, traceability, and review practice — the problems that actually show up in DO-178C, ISO 26262, EN 50128, and IEC 62304 programs, and what fixes them.

Written by practitioners who have prepared and defended certification evidence — not repackaged standards summaries.
The Real Cost of Getting Certification Wrong
You can spend $7.5 billion and still not get certified. Three programmes that prove it — SpaceJet, the KC-46 tanker, and Eclipse Aviation — and why the overrun always begins at requirement review.
DO-178C Traceability: Spreadsheet vs Single Thread
