Sketchplanations - A weekly explanation in a sketch

Given a capable and intelligent person or group of people, errors rarely originate in the execution of a plan, though the plan itself may fail. Instead, errors occur in the principles underlying the development of the plan. Therefore, it's important to base a plan or a framework on the correct principles.

Peter Principle — “The selection of a candidate for a position is based on the candidate’s performance in their current role, rather than on abilities relevant to the intended role. Thus, employees only stop being promoted once they can no longer perform effectively, and ‘managers rise to the level of their incompetence.’”
