The short answer
Assume the plan failed, privately list plausible reasons, then rank the few risks you can prevent or detect early. A pre-mortem improves a plan when it produces owners and triggers, not merely a longer worry list.
Decision methods work when they expose assumptions, stopping rules and trade-offs. They fail when the framework becomes a way to postpone ownership of the choice.

A realistic decision example
A team planning a launch imagines that the launch failed because testing started late, one owner was unclear and a supplier slipped. Those causes can become actions, owners and warning dates before the plan begins.
Evidence that could change the choice
Collect possible failure causes independently, then look for signals already available: missed milestones, unresolved dependencies, capacity gaps and assumptions with no owner.
A practical decision process
Use this sequence for the choice in front of you. Stop when the remaining uncertainty cannot be reduced by a practical check, conversation or small test.
State the proposed decision and time horizon.
Imagine the outcome clearly failed.
Generate causes independently before discussing them.
Rank probability, impact and detectability.
Assign prevention steps and warning signs.
Record the evidence behind the choice and what remains uncertain. That note makes a later review more useful because it separates the quality of the process from luck in the outcome.

Questions that test the reasoning
Answer these in plain language. If the decision is shared, answer separately before comparing responses; independent answers reduce the pressure to conform too early.
- What failure would surprise the team least?
- What are we reluctant to say aloud?
- Which early signal would justify changing course?
Reasoning mistakes to avoid
Watch for these patterns while working through this particular choice:
- Using the exercise to veto every plan
- Listing vague risks with no owner
- Ignoring success conditions
Compare these failure patterns with the other decision-making guides before applying the same method elsewhere.
A framework should make judgment more visible, not manufacture certainty. Where the choice involves safety, health, legal rights or significant financial consequences, take the organized questions to a qualified professional who can evaluate your circumstances.
Use the Decision Matrix tool
A decision matrix makes priorities visible by multiplying each factor's importance by each option's score. The arithmetic organizes judgment; it does not make the inputs objective.
