"Standardization makes things efficient, but it also makes them fragile.
Standards exist for the moments when you are tired, rushed, or politically pressured. In a reliability improvement that shifts risk elsewhere, they keep improvisation from becoming policy. When they are vague, enforcement becomes personal.
In a reliability improvement that shifts risk elsewhere, people comply with what is enforced, not what is written. If exceptions are informal, you end up with a standard no one can defend and a process no one trusts. Clarity is not certainty; it is a small commitment the team can execute without reopening the decision at every update. If you cannot describe the boundary simply, the boundary will not survive escalation and reorgs.
Charles Perrow is useful here because it forces precision. Write the win and the cost as two lines, so neither becomes invisible. Make it falsifiable.
