Strong answer
Protect credibility by replacing the promise with a reliable process.
- Coach the CSM to push back internally with the risk of another missed commitment and a safer alternative.
- Offer the customer a specific discovery checkpoint, owner, and decision date.
- State what the team can validate now and what remains unknown.
- Ask leadership to approve the commitment boundary before the message goes out.
- Document the approved boundary so the next update does not get reinterpreted as a delivery promise.
