tuc,
And I know quite a few non-engineer IPTLs and project managers who resent the fact that their junior staffs actually have more responsibility and authority than they do. These, I suspect, are the people Safeware was referring to.
Unfortunately, no. Said person was an engineer who just felt it 'career limiting' to be seen as the one who's system wasn't going to be 'ready' in time if the safety issues raised were to be effectively addressed.
As for IPT's having to justify why the haven't nb'd the advice from BD, the safety case presented up the line should cover areas where the IPT is taking responsibility for the risk in not implementing recommendations.
But therein lies more cans.
