For large organizations to operate effectively, they need some slack.

The slack helps absorb surprise without a compounding cascade of thrash.

It also allows little seedlings of greatness to grow.

Don't think of slack in a system as "employees sitting around twiddling their thumbs" or "doing unimportant hobby projects" or "playing foosball".

Think of it instead as "doing preemptible work that is important but not urgent."

Doing the P2s. Which, over time, can add up significantly.
