Just curious. How many safety analysis have you been involved with, with writing or reviewing?
FHA, FMEA, FTA, etc.
Having been involved with several and what has been published about the process with MCAS I disagree with your assessment.
I've seen many similar to what was done with MCAS. That's the standard way of doing them. Just as Boeing's use of their own test pilots for flight/SIM testing or using uncontrolled stab movement instead of simulating faults that could led to that are common.
There are processes issues that need dealt with. I don't know how they are going to fix it and maintain a commercially viable process.
They can move the line a bit to cover more cases, but there will still be cases not dealt with.
