# Decision Brief

## Decision

- Decision ID:
- Owner:
- Deadline:
- Decision question:
- Current default action if no new information is acquired:
- Stakes:
- Reversibility: reversible / costly to reverse / irreversible
- Boundary status: undefined / far / near / locked

## Real Options

| Option | Action | Expected benefit | Main risk |
| --- | --- | --- | --- |
| A |  |  |  |
| B |  |  |  |

## Utility and Loss

What is being optimized? What is the cost of choosing badly? Which assumptions drive the option ranking?

## Uncertainty Map

| Uncertainty | Current belief/range | Confidence | Impact if wrong | Could change option ranking? |
| --- | --- | --- | --- | --- |
|  |  |  |  |  |

## Candidate Information Actions

List no more than three. Each action must target one uncertainty and state what signal would change the decision.

| Information action | Target uncertainty | Signal that favors A | Signal that favors B | Cost/delay | Net VOI judgment |
| --- | --- | --- | --- | --- | --- |
|  |  |  |  |  |  |

## Selected Probe

- Action:
- Why this is the smallest high-value probe:
- Sample/evidence gate:
- Owner and due date:

## Stop Rule

Stop collecting information when the preferred action is robust, marginal VOI no longer exceeds cost, the evidence gate or deadline is reached, or remaining uncertainty cannot change action.

## Outcome

- Observed signal:
- Prior:
- Posterior:
- Action before information:
- Action after information:
- Decision changed: yes / no
- Residual uncertainty:
- Stop reason:
- Decision-log reference:
