A standard should improve behavior before it improves appearance.

A standard that only changes how things look has not done anything, and it is quite common, since appearances are easier to adjust than practice. A real standard changes what you actually do, the extra check you now run, the thing you no longer send unfinished. If nothing about your behaviour is different, the standard is decorative.

Ask what you do differently now that this standard exists. If you cannot name an action, make one. Standards live in specific changed behaviours rather than in intentions about quality.
