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

  1. List decision points. Identify 5–15 points where a commander must choose among options.

  2. Define the trigger. For each decision point, define an observable trigger that indicates the decision must be made.

  3. Define the decision authority. Who decides if the commander is unavailable? Make delegation explicit.

  4. Define information requirements. What must be known to decide? Keep it short; avoid wish lists.

  5. Define the action. What is the pre-planned action if the trigger occurs?

  6. 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?
