Build a Decision Support Matrix
A decision support matrix is an anti-surprise tool. It prevents the “we must decide now but we didn’t prepare” failure mode.
Steps
-
List decision points. Identify 5–15 points where a commander must choose among options.
-
Define the trigger. For each decision point, define an observable trigger that indicates the decision must be made.
-
Define the decision authority. Who decides if the commander is unavailable? Make delegation explicit.
-
Define information requirements. What must be known to decide? Keep it short; avoid wish lists.
-
Define the action. What is the pre-planned action if the trigger occurs?
-
Tie to collection and reporting. Ensure someone is responsible for detecting triggers and reporting them in time.
Output
A DSM table with columns:
- Decision point
- Trigger
- Decision authority
- Information required
- Action
- Who reports / when
Stress-test
Pick the three highest-risk decision points and ask: if communications are degraded, how late can the trigger be detected before the decision becomes useless?
