Use fictional or approved information. Do not put secrets in this worksheet.

## Learning objectives
- Separate requirements, assumptions, and observations in a decision.
- Compare realistic alternatives against the same scope.
- Specify a review trigger that can change the decision.

## Exercise
Write a one-page decision for the fictional contract application in this lesson. Compare three options. Include one reason to reject your preferred option, one unresolved assumption, and a measurable review trigger.

## Your response
- Scenario and scope:
- Assumptions and open questions:
- Proposed answer or decision, with reasons:

## Verify your response
| Claim or criterion | Evidence or test | Result or gap | Owner |
| --- | --- | --- | --- |
| | | | |
| | | | |
| | | | |

## Next action
- Action, owner, and date:
- When will you review this response?

## Principle to retain
A decision record explains why an option fits the current evidence and when that conclusion must be reviewed.
