A couple of thoughts on the recent discussion....

Sorry, a good few places do it the other way around. And therein lies one problem with a global industry.

I’d be interested to know of the QA plan, most obviously failure modes, and how it was executed and signed off.
Perhaps more important is requirement capture before it goes off to the coders (wherever they may be). If assumptions are made at this point - be they about what pilots will know or be able to handle, or the training that they will get to ensure they have sufficient knowledge/competence of a particular system, to pull a couple of examples out of the air - it is vital that they are verified to be correct.
