Strong standards simplify decisions because some options eliminate themselves.

A firm standard removes options before you have to weigh them, which saves an enormous amount of deliberation. If certain things are simply not done, whole categories of decision never reach you, and the energy that would have gone into agonising goes into the work. Weak standards mean every situation gets negotiated from scratch.

Decide a few things in advance and treat them as settled. What you will not ship, what you will not agree to, what always gets checked. The relief comes not from the standard itself but from no longer having to reconsider it.
