> and all blameless post mortems do is act as an excuse to avoid raising the bar
"Well, there's your problem, right there."
The entire point of doing blameless post-mortems is to correctly identify problems for resolution. If management doesn't drive changes in response (process, training, communication, whatever), you have a different problem to solve before they'll do any good.
I imagine blameless postmortems sometimes happen because people want to avoid blame.
So they argue that all the cool places do "blameless". We should try that too!
And then the organization doesn't understand the actual concept behind the idea (nor did the suggestor want that). Instead the organization learns "we have decided not to blame anyone". And then everyone involved is satisfied.
