What concept is described by people being promoted beyond their level of ability?

The concept described by people being promoted beyond their level of ability is the Peter Principle. This principle posits that individuals within an organization will continue to be promoted until they reach a level at which they are no longer competent. It highlights a critical flaw in many hierarchies, as employees who excel in their roles may be moved up to positions that require different skills or greater responsibilities, ultimately leading to inefficiency and ineffectiveness in those higher roles.

By understanding the Peter Principle, organizations can better assess employee capabilities and implement training or support strategies to ensure that promotions align with an individual's strengths and development. This principle underscores the importance of considering not just past performance but also the unique demands of a new position when making promotion decisions.
