We can improve our planning. We can fight back against competitor blindness and irrational optimism. Daniel Kahneman recommends an idea developed by Gary Klein called a premortem.
A typical premortem begins after the team has been briefed on the plan. The leader starts the exercise by informing everyone that the project has failed spectacularly. Over the next few minutes those in the room independently write down every reason they can think of for the failure—especially the kinds of things they ordinarily wouldn’t mention as potential problems, for fear of being impolitic. For example, in a session held at one Fortune 50–size company, an executive suggested that a billion-dollar environmental sustainability project had “failed” because interest waned when the CEO retired. Another pinned the failure on a dilution of the business case after a government agency revised its policies.
Next the leader asks each team member, starting with the project manager, to read one reason from his or her list; everyone states a different reason until all have been recorded. After the session is over, the project manager reviews the list, looking for ways to strengthen the plan.
