Silent Risk Generation: 10 min
Silently list every factor that led to the total failure
Round Robin Failure Sharing: 10 min
Share items around the room one by one without discussion
Risk Categorization and Priority: 10 min
Cluster similar risks and rank them by severity and likelihood

About this routine

Cognitive psychologist Gary Klein developed the pre-mortem technique in 2007 as a way to overcome groupthink and overconfidence during project planning. Unlike a standard post-mortem that analyzes what went wrong after a project fails, a Gary Klein pre-mortem operates in reverse. The team gathers before launch and assumes the project has already failed completely, using prospective hindsight to uncover hidden risks.

Research shows that imagining an outcome as already accomplished increases people ability to correctly identify reasons for future events by 30 percent. During the audit, team members silently write down every imaginable cause for catastrophe, from subtle operational gaps to major market shifts. By making it safe and expected to voice concerns, the session turns potential whistleblowers into helpful analysts.

The session concludes by sorting vulnerabilities into actionable categories and assigning owners to build preventive measures. Running this 45 minute review with a visual schedule before major milestones helps teams protect investments, refine timelines, and address silent doubts early.

Why this routine works

Reduces overconfidence and optimism bias prior to project execution.
Encourages candid input from team members who usually hold back concerns.
Converts vague anxiety into concrete preventive tasks with clear ownership.

FAQ

What is a Gary Klein pre-mortem?

A pre-mortem is a project management exercise developed by Gary Klein where a team assumes a project has failed before it starts, working backward to identify and prevent potential risks.

How long does a pre-mortem audit take?

A complete Gary Klein pre-mortem failure audit takes 45 minutes, divided into setup, silent risk generation, sharing, and mitigation planning.

How does a pre-mortem differ from a post-mortem?

A post-mortem analyzes why a project failed after the event occurs. A pre-mortem takes place before launch, using hypothetical failure to prevent disasters in advance.
