As a former Systems Engineer who worked on avionics, I would tend to agree; a major change to a system should have at least triggered the integration-level engineers (called the Platform team at my former job) to think hard about potential broad impacts. It should have resulted in that team actively seeking buy-in, and clear communication that all subsystems comprehended precisely what was changing. It likely should have triggered some kind of additional scrutiny from the safety organization. That it didn’t is heartbreaking. It seems like either some common practices were not followed or were rushed. I can’t see Boeing keeping their CMMI certification level after this news breaks. Certainly some major steps were skipped in the Systems Engineering process.
