The @ddwoods2 classic How Adaptive Systems Fail in ‘Resilience Engineering in Practice’ 2011 1) being stuck in outdated behaviours 2) loss of adaptive capacity 3) working at cross purposes These are so relevant currently and understanding these patterns helps us call them out.
The reading for today in Human Factors & Systems Safety comes from Christopher P. Nemeth and Erik Hollnagel. Resilience Engineering Perspectives, Volume 1 Remaining Sensitive to the Possibility of Failure routledge.com/Resilience-Eng…
"Many organizations have driven post-incident reviews to become pallid, vapid, mechanical exercises whose value is limited to producing a defensible argument that management is occurring." - I can certainly relate to this.

You can’t solve coordination problems with accountability.
Two of the biggest source of incidents I’ve seen are: 1. Legacy code 2. Migrating away from legacy code The conclusion is clear: you should only write non-legacy code

You can say that your new policy isn't punitive all you want but if it takes away privileges in response to norm-violating behavior, it is punishment by definition. I keep seeing leaders who think that calling a spade something else makes it not a spade.
