What is it?

Premortem is an analytical / thought experiment technique, which is frequently used for risk management, strategic or product decision evaluation.

The method originates from Gary Klein (HBR article) and was made popular by. The Nobel winner Daniel Kahneman in his book “Thinking Fast and Slow”.

The approach is really simple and transports the team in the distant future in which the product would be launched and failed miserably. The team is asked to describe the reasons, the root causes really behind the notorious failure.

The practice is very similar to the black hat in the Six Thinking Hats brainstorming approach or the News Headlines. The News Headlines is a really a variation of the premortem practice using visual facilitation.

Why use it?

The method is simple, fast and cheap to execute. You do not need to prime the group or invest in any upfront training.

It is a great way to identify risks and threats, which can be later addressed, e.g. through early experiments or other actions.

The benefits of this method when making important product decisions:

  • Eliminates groupthink
  • Overcomes blind spots - as planning far ahead tends to introduce risks of overlooking details
  • A psychologically safe way to surface disagreements on important details of the product design - often in lack of psychological safety, people would not point out gaps or deficiencies in the design to avoid appearing as pessimists or getting in a debate over the relevance of their concerns

This practice complements nicely Start at the End, Whole Product Plotting, Design the box, News Headlines and any other product design practice.

It can provide a good approach for retrospectives too.
