In his 1968 book The Peter Principle, Canadian educational scholar and sociologist Dr. Laurence J. Peter introduced the theory, suggesting that an employee’s failure to meet the demands of a promoted position may not stem from overall incompetence, but rather from the fact that the new role requires different skills than the employee has. For instance, an employee who excels at assembly tasks may be promoted to a leadership role without having demonstrated the necessary skills to be an effective leader first.
When newly promoted managers are inadequately suited to their roles, their ability to provide effective leadership and guidance to their teams may be compromised. This can result in a higher incidence of errors or defects, particularly if their new responsibilities involve quality control. These challenges can cascade throughout the organization, as employees under sub-optimal management may also experience a rise in mistakes. Additionally, the continuous promotion of lower-level workers who lack the necessary skills or training for managerial positions can lead to multiple layers of ineffective management. This situation can further undermine employee morale, as the remaining workforce may develop resentment towards their deficient leadership. The Peter Principle is not simply a mistake, but rather an unavoidable outcome of any system that promotes people based on their performance in a current role. When companies understand this, they can adjust their strategies to minimize its effects. Typically, businesses counteract the Peter Principle by raising the standards required for promotion. This is especially necessary when temporary factors—such as luck or short-term performance—play a significant role in someone's success, rather than long-term ability or consistent performance. The greater the influence of these temporary factors, the more the company needs to increase the criteria for promotion to avoid promoting someone beyond their true capabilities.
How to avoid?
Promotions should be based on the skills required for the next role, not just the employee’s success in their current position. For example, a great technician may not necessarily be a great manager, so it is important to evaluate whether the person has the right skills for the next level.
Organizations should aim to promote a culture of continuous learning, particularly focusing on leadership and management skills. Employees who show promise in their roles should be encouraged to participate in training or mentorship programs to develop the necessary skills for leadership positions, such as communication, decision-making, and conflict resolution. It would also be beneficial for companies to set clear, role-specific criteria for promotions that go beyond just performance metrics in the current role. This could include creating skill matrices or assessments that consider not only technical skills but also soft skills (e.g., leadership, team collaboration, strategic thinking) that are required for the next role. Additionally, organizations should consider conducting regular skill assessments to monitor employees’ readiness for higher-level roles. This could include performance reviews, 360-degree feedback, or management assessments to ensure employees are developing the necessary skills at each career stage.

Implementing job rotation programs could also be valuable. These programs allow employees to experience different roles within the company before being promoted into one, helping them develop a broader range of skills and providing the organization with a better understanding of the employee's strengths and weaknesses. This can prevent employees from becoming stuck in a role that doesn’t suit them. Furthermore, promotions should be based on long-term, consistent performance rather than short-term success or luck. Companies should take into account an employee’s growth over time, their ability to handle challenges, and their consistency in delivering results when considering a promotion.
Finally, when employees are promoted to managerial positions, organizations should ensure they have a strong support system in place. This may include mentoring from experienced leaders or leadership training programs, which can help new managers feel more confident and avoid being left to figure things out on their own.
