Power.
'The law always limits every power it gives.'
- David Hume
Step 2 of the Five Steps to a Good Decision: Name the Issue.
It's only an Issue if you have the power to make a decision in support of your Widget.
Ask: What power do I have?
Look for it in your contract.
Look for it in your policies.
Look for it in what your boss has said she expects of you.
No power? Then there is no Issue and therefore no decision required of you. Inform someone who does have the power.
Power?
Then ask:
What are the conditions or restrictions on the exercise of that power?
Welcome them. They give focus. Quieten the noise.
If you have a power - you have limits.
Be clear on what they are.
(You'll often find them in your Values.)
Then continue to Step 3.
