A completed investigation is something to tick a box, I guess, but it's a far cry from there to prevention of similar future occurrences. Don't get me wrong, a detailed investigation properly conducted and reported is an admirable achievement, but it doesn't fix anything.

If yes, then “what we want” is for the waste of resources that is the ATSB, or at least the aviation bit of it, to end. Just set up a piece of software to produce reports with random homilies about lessons that have been learnt before, and be done with it.
