Inversion Thinking, also called a pre-mortem, complements positive visualization by imagining that an initiative has failed and identifying what could have caused the outcome. The critical second stage is response planning: for each meaningful risk, decide what to do if it occurs. This shrinks vague fear into specific, manageable scenarios and creates instructions while judgment is calm. In teams, independent input exposes operational risks that a single leader cannot see. Rehearsal can also build self-efficacy, as demonstrated by Michael Phelps mentally practicing equipment failures and other disruptions before competition. When an adverse event occurs, the person or team can execute a prepared response rather than inventing one while stressed, disappointed, or overwhelmed.
Origin
Shade Zahrai connected project-management pre-mortems with research on goal implementation and Michael Phelps's adverse-scenario visualization. Jasmine Star described applying the method to a new subsidiary launch. Extracted from The Jasmine Star Show.
Core principles
- 01Visualizing success is incomplete without preparing for setbacks.
- 02Anticipated risks become more manageable when paired with responses.
- 03Planning under calm conditions improves execution under stress.
- 04Multiple perspectives reveal risks one person will miss.
- 05Prepared responses build evidence that adversity can be handled.
How to run it
- 1
Define the Mission
State the intended outcome, decision horizon, and important constraints. Ensure participants are analyzing the same initiative.
Pro tip Use a concrete outcome and date rather than a broad aspiration.
Watch out A vague mission produces vague risks.
- 2
Assume Failure
Imagine that the initiative has failed or the performance has been seriously disrupted. Work backward to identify the causes and warning signs.
Pro tip Phrase the prompt in the past tense, as though the failure has already happened.
Watch out Do not stop at emotionally vivid risks while ignoring routine operational failures.
- 3
Collect Independent Risks
Have stakeholders list risks before discussing them together. Combine perspectives from different functions or areas of expertise.
Pro tip Give participants preparation time so the loudest voice does not define the list.
Watch out Group discussion held too early can suppress unusual but valuable concerns.
- 4
Prioritize the Scenarios
Evaluate likelihood, impact, detectability, and reversibility. Focus detailed planning on the scenarios that matter most.
Pro tip Separate existential risks from tolerable inconveniences.
Watch out Trying to eliminate every possible risk can become another form of Failure to Launch.
- 5
Plan the Response
Specify what will happen if each priority scenario occurs, including ownership, triggers, and immediate actions. Prepare resources or fallback routes where practical.
Pro tip Write responses so they remain usable when the team is stressed.
Watch out Risk identification without response planning magnifies fear instead of building readiness.
- 6
Rehearse and Decide
Mentally rehearse or simulate important scenarios, then decide whether to proceed after counting the cost. Update plans when new evidence emerges.
Pro tip Practice the most disruptive scenarios, not only the most likely ones.
Watch out Preparedness does not guarantee that every real event will match the plan.
In the wild
Michael Phelps rehearsed adverse race scenarios, including goggles filling with water. During the 2008 Olympic 200-meter butterfly final, his goggles filled almost immediately, but he relied on prior mental preparation, swam blind for 175 meters, won gold, and broke the world record.
→ Adverse-scenario rehearsal enabled effective execution during an unexpected equipment failure.
Before launching a new subsidiary, Jasmine Star asked each department head to independently list everything that could go wrong. The combined review surfaced risks she had not anticipated, after which the team explicitly counted the cost and chose to proceed.
→ The launch decision became more informed and the team entered execution with shared awareness of the risks.
Common mistakes
Listing Risks Without Responses
Unbounded failure visualization can increase anxiety; each priority risk needs a planned action or acceptance decision.
Relying on One Perspective
Leaders frequently miss risks visible to marketing, fulfillment, customer success, technical, or operational stakeholders.
Using the Pre-Mortem to Avoid Action
The exercise should support a decision and preparation, not justify endless scenario generation.
Is it for you?
Best for
It is best for consequential launches, projects, competitions, and decisions involving uncertainty or multiple stakeholders.
Not ideal for
It is not ideal when severe unmanaged anxiety makes broad failure visualization destabilizing rather than constructive.
From the transcript
“This is called inversion thinking or a pre mortem in the project management world.”
“But then the important second step that you must not forget, which is what you do plan. What will you do if it happens?”
“It reminds you that no matter what happens, you can handle it.”
