I find it quite remarkable that it takes such a long windup to finally conclude that the crew did not do everything perfectly. Duh. No human ever does.

And then it just stops. What is the point of finger-pointing? How can that help anyone in any way? (Except perhaps Boeing's reputation, but even that is doubtful.)

A finding of "Human Error", can never be the end of an analysis, rather it must be the start of asking questions such as:
  • What was the exact situation the operators were in?
  • What was the information they could get?
  • Was some information maybe ambiguous? Even contradictory? Hard to find?
  • How much time did they have to find it?
  • How much time did they have to analyse it?
  • Were they trained to evaluate the information properly?
  • Were there perhaps multiple anomalies requiring different, possibly even contradictory procedures?
  • Was there perhaps cognitive overload?
  • Did they (could they?) have an understanding of why the system did what it did?
  • What additional information do we have now, that the operators at the time did not have? (The easy one: we know that what they did eventually led to an unrecoverable situation. They didn't. Or else they wouldn't have done it.)
  • Which again leads to: why did they do what they did?
  • How can we prevent:
    • ... crews from doing the same things again, or better still:
    • ... anyone from getting into the situation in the first place?
I repeat here the image I posted way back that makes these ideas very clear:
