Without commenting about the frequency of negligence myself, I suspect at least that you and GP are in agreement.

I doubt GP is suggesting ‘go ahead and be negligent to feedback and guardrails that let you course correct early.’

Plugging the Cynefin framework as a useful technique for practitioners here. It doesn’t have to be hard to choose whether or not rigorous planning is appropriate for the task at hand, versus probe-test-backtrack with tight iteration loops.
