If you manage developers or product folk, do you allow them to work when you're not looking over their shoulder? All developers can be managers/team leads now. You plan, you delegate, you review.

You're welcome to not do this, surely that's appropriate in quite a few areas of work, but many of us are because we can get more work done than if we we're micromanaging every line of code change. For startups, where a bit of quality can suffer in favor of finding market fit, this is huge.
