Boeing Co. limited the role of its own pilots in the final stages of developing the 737 MAX flight-control system implicated in two fatal crashes, departing from a longstanding practice of seeking their detailed input, people familiar with the matter said.

As a result, Boeing test pilots and senior pilots involved in the MAX' development didn't receive detailed briefings about how fast or steeply the automated system known as MCAS could push down a plane' nose, these people said. Nor were they informed that the system relied on a single sensor, rather than two, to verify the accuracy of incoming data about the angle of a plane's nose, they added.

    'Best practices' sounds like there might be other acceptable practices? I don't see how.

    Leaving metal shavings inside a car or mobile home is probably ok, because things tend to gravitate and stay put.
    If they don't and the thing stops working, you can always pull over and figure out what happened.

    This is not the case in something that flys. Expecting things to stay put and being able to just pull over and stop are not options.
    An airplane mechanic that leaves metal shavings or spare parts lying about has simply not done his job.

    A management plan that leads to this has a serious problem.

    Exactly. Management didn't care.
    They moved some construction to a cheap Southern state with no union I presume all in the name of cutting costs.
    Something tends to give when the overall focus is cheaper and faster. Don't think management is unaware. They gambled on it by pushing quality aside thinking it wouldn't matter (much).

      That was both cutting costs on that plane, and putting pressure on the unions back in Everett. Combined with the headquarter move to Chicago, the whole plan was designed to tell the historical expensive workers that the diversified company wasn't stuck having to deal with them, so they'd better be reasonable.

      Given the results, it seems to have backfired (if the executives can realize that)
