Err on the side of do

Without action now you have no action ever.

the asap principle: If the cost to undo the decision is low, make it as soon as possible.

Beware! We often defer decisions because we have doubts. But not making a decision is a decision in itself. If you delay a resolution it is often an unconscious decision, one that you do not communicate. This leads to uncertainty in a team. So if you want to make a decision later, be sure to communicate this clearly.
