Assumptions Should Have Expiration Dates

The useful idea
- Understand
Projects use assumptions when important facts are not yet available.
- Connect
Changes in customers, costs, constraints, or technology can silently make an early estimate invalid.
- Apply
An owner and review date turn a hidden belief into a condition that the team can revisit.
Why this matters

Try this
Record each major assumption with an owner and review date.
