TLDR;
This TEDx talk outlines a three-step process for effective decision-making, applicable to both professional and personal scenarios. It emphasises challenging constraints, conducting a "premortem" to anticipate potential failures, and meticulously checking basic details. The talk uses real-world examples, including a Stanford experiment, the "cobra effect" in colonial India, the Mars Climate Orbiter failure, and the "Miracle on the Hudson," to illustrate these principles.
- Challenge the constraints to foster innovative thinking.
- Embrace a premortem to anticipate and mitigate potential failures.
- Check the basics to prevent small details from derailing your decisions.
The $5 Challenge: Challenging Constraints [0:01]
A Stanford University entrepreneurship class was given a challenge: teams received $5 and had a short time to make as much money as possible. The winning team didn't use the money; instead, they sold presentation rights to a company wanting to recruit Stanford students. This highlights the importance of challenging constraints, in this case, the $5, to identify the real opportunity. The speaker argues that constraints often stifle innovative ideas, and the first step to better decision-making is to question these limitations.
The Power of Premortems: Learning from the Cobra Effect [3:23]
The speaker introduces the concept of a "premortem," which involves considering potential failures before making a decision. He contrasts this with the common practice of postmortems, where reflection occurs after an event. To illustrate this, he tells the story of the "cobra effect" in colonial India, where a bounty on dead cobras led to cobra breeding, ultimately worsening the problem when the bounty was removed. This demonstrates how a premortem could have identified the unintended consequences of the British government's policy.
Checking the Basics: The Mars Climate Orbiter [6:24]
The third step in effective decision-making is to check the basics. The speaker uses the example of the 1999 NASA Mars Climate Orbiter mission, which failed because one team used the metric system while another used imperial units, leading to a navigational error. This preventable mistake, made by highly intelligent individuals, underscores the importance of not overlooking fundamental details, even when dealing with complex strategic plans.
The Miracle on the Hudson: Applying All Three Steps [9:25]
The speaker concludes with the story of US Airways Flight 1549, the "Miracle on the Hudson," where Captain Sully Sullenberger safely landed a plane on the Hudson River after a bird strike disabled both engines. Sully challenged the constraints by considering the Hudson River as a landing option, conducted a premortem by assessing the aircraft's floatation time and the feasibility of a water rescue, and checked the basics by having his co-pilot confirm airspeed and altitude. Even after landing, he ensured all passengers were off the plane. This example encapsulates all three steps of effective decision-making.
