What to do?
Go and talk
Document
Just change your product once uncertainty is clarified
How it works:
Formulating phrases helps to clarify uncertainty
Sharing thoughts/assumptions help to avoid ambiguity
Document (email, etc.) acts as an evidence and safeguard of clarified uncertainty

What NOT to do?
Avoid not expressed assumptions
Don’t predict details that are not important now – YAGNI
Don’t punish colleagues/customers/users
Don’t get disappointed – work with uncertainty is what we’re paid for.
