For 10 years I've heard how you need to learn from your mistakes and it seems quite a reasonable mantra. But the problem I've got with learning from mistakes is how quickly do you learn.
Some people and some organisations seem to learn really quickly, others, more like myself, take a while longer, others take the whole of their existence.
So the question I've got is how do measure the responsiveness of someone, some organisation, to learning from their mistakes?
What metric could we use to tune performance?
Not sure, but maybe we can think something up.
