What makes shallow incident data shallow?

"This might just sound like a matter of swapping out words, but it's actually a way of changing approaches"

If the decisions we make during an incident impact how the incident progresses, then ignoring those decision-making processes and what information they are based on ‘in the moment’ is detrimental to how well the team will learn.

In all this hurry to get things done, to move on to the next project, to dig wide and deep into "the good stuff", it's easy to forget that learning, the real concrete durable expertise needed in a crisis, doesn't happen overnight.
