A clinical user cannot access the data they need before a critical workflow. A clinical team loses visibility into something they were supposed to review.

I have been doing this for over ten years. And honestly, the thing that surprises me most is not how different safety-critical QA is from regular software testing. It is how many of the problems are exactly the same — just with higher stakes attached.

Here is what that environment actually taught me. The lesson is not about process or tooling. It is about what happens to an engineering culture when the...
