A plan relies on a third party’s behavior that has been assumed rather than explicitly confirmed.
The useful bits
- Assumption in the project plan
- Evidence currently available
- A useful reply supplies the confirmed source or states that the dependency remains uncertain.
Before you write
Use this example when a plan relies on a third party’s behavior that has been assumed rather than explicitly confirmed. Gather the details below so the recipient can act without asking you to reconstruct the situation.
- Assumption in the project plan
- Evidence currently available
- Person who can verify it externally
An email you can adapt
The subject “Verification needed: [dependency assumption]” identifies the request. Replace each bracketed field with a checked detail and remove any sentence that does not describe your situation.
Subject: Verification needed: [dependency assumption] Hi [name], The current plan assumes that [third party] will provide [dependency] by [date]. I cannot find a confirmed source for that assumption. Could [owner] verify the commitment through the approved contact route and record the result at [location]? Until then, please mark the date as unconfirmed. If the assumption is wrong, we will need to review [affected work] rather than quietly carry the same schedule forward. Best, [sender]
Check the boundary
A repeated assumption can look authoritative in a tracker even when no external party has agreed to it.
What a useful reply should settle
A useful reply supplies the confirmed source or states that the dependency remains uncertain.
Reassess dependent work once verified information is available and make the changed assumption visible.
