The Peter Principle is a management/organizational theory that says employees who perform well are promoted until they reach a job level for which they are no longer competent. In other words, people tend to rise “to their level of incompetence”: competence in one role leads to promotion, but success in a prior role does not guarantee the skills required for the next role.
Key Takeaways
– The Peter Principle explains why capable individual contributors can become ineffective managers after promotion.
– Promotions based on past output (rather than the skills needed for the new role) are a core driver.
– The result can be layers of management that lack the abilities required for their positions, harming productivity and morale.
– Organizations can reduce the effect by assessing role-specific competencies, using training and trial periods, and creating career paths that don’t force everyone into management.

History
– Origin: Coined by Dr. Laurence J. Peter in his 1968–1969 book The Peter Principle. Peter joked that “the cream rises until it sours,” arguing that promotion systems reward demonstrable competence in a role—without testing whether the promoted person has the different skills required in the next role.
– Empirical work: Recent economic research (e.g., Benson, Li, and Shue, Quarterly Journal of Economics, 2018) analyzed real firm promotion practices and found evidence consistent with the Peter Principle: firms tend to promote top performers based on past sales performance, and many become poorer-performing managers.
Productivity and Morale
– Misaligned skills: When promoted employees lack managerial, strategic, or communication skills required by the new role, they may make poor decisions, provide insufficient guidance, or mishandle personnel issues.
– Knock-on effects: Poor leadership increases errors, reduces team effectiveness, and can heighten churn among high performers reporting to ineffective managers.
– Morale and fairness: Employees who see promotions landing people ill-suited for leadership roles may feel demotivated or resentful—especially if promotion criteria are opaque or perceived as unfair.
How Companies Avoid the Peter Principle (Practical Steps)
Organizations can reduce the risk of promoting people into roles they cannot perform. Key, practical steps include:
1. Define role-specific competencies
– Create clear competency models for each role (technical, managerial, interpersonal, strategic thinking). Promotions should require evidence of those competencies, not only past output.
2. Use structured promotion assessments
– Assessment centers, work samples, case exercises, situational judgment tests, and behavioral interviews that simulate the promoted role’s challenges.
3. Invest in training and development before and after promotion
– Management training, coaching, and mentoring programs specifically focused on skills new managers need (e.g., performance coaching, delegation, conflict resolution).
4. Create alternative career ladders
– Offer dual tracks (technical/specialist vs. managerial) so high-performing contributors can advance and be rewarded without being forced into people-management roles.
5. Trial/transition periods with measurable milestones
– Use trial leadership assignments, acting roles, or probationary periods with clear goals and metrics. If there’s a mismatch, offer alternatives rather than forcing permanence.
6. Use 360-degree feedback and objective metrics
– Gather input from peers, direct reports, and supervisors to assess a new manager’s effectiveness; tie evaluation to demonstrable, time-bound improvement plans.
7. Promote lateral moves and job rotations
– Rotations expose candidates to a wider set of duties and better reveal whether they have the skills for leadership or other roles.
8. Consider external hiring for critical leadership roles
– For some jobs, hiring experienced managers from outside can be preferable to promoting based only on prior internal performance.
9. Make promotion criteria transparent and equitable
– Clear expectations reduce perceptions of unfairness and allow employees to prepare for roles they want.
10. Design jobs to reduce single-person failure points
– Use matrix teams, shared leadership, or distributed decision-making so a single incompetent manager cannot cause system-wide failure.
Important (Limitations and Interpretations)
– Not a universal law: The Peter Principle is a descriptive heuristic, not a determinative law. Many organizations successfully promote leaders who adapt and grow.
– Context matters: Some skills transfer well (technical expertise to technical leadership), but others don’t (high individual sales performance doesn’t necessarily predict managerial skill).
– Trade-offs: Rigidly preventing technical stars from entering management can create retention issues; organizations should offer attractive alternatives and rewards.
Example (Illustrative Scenario)
– A top-performing software developer is promoted to Engineering Manager because of coding excellence. Managerial duties (people management, hiring, prioritization, cross-team coordination) require different skills. The new manager struggles with delegation and giving feedback; team velocity and morale fall. With earlier assessment, management training, or a parallel senior-engineer track, the company could have avoided or mitigated that outcome.
What Is the Corollary to the Peter Principle?
– Peter’s Corollary: Over time, every position in a hierarchy will be filled by someone incompetent to perform its duties. If promotion continues without corrective measures, incompetence accumulates across levels, worsening organizational performance.
What Is the Dilbert Principle?
– Coined by Scott Adams (creator of the Dilbert comic), the Dilbert Principle is a satirical counterpart: companies promote their least-competent employees to management so they are less likely to interfere with productive work. While the Peter Principle explains incompetence in management as the result of promoting the competent, the Dilbert Principle suggests intentional promotion of incompetence to reduce harm to core production. Both offer different—one more empirical, one more cynical—explanations for poor leadership.
What Government Agency Monitors a Company’s Employment Practices?
– In the United States, the primary federal agency for enforcing workplace anti-discrimination law is the Equal Employment Opportunity Commission (EEOC). The EEOC enforces laws prohibiting employment discrimination in hiring, firing, promotions, harassment, and related practices.
– Other U.S. agencies with employment-related oversight:
– U.S. Department of Labor (DOL): wage and hour, workplace posting requirements, family and medical leave rules.
– Occupational Safety and Health Administration (OSHA): workplace safety and health.
– State labor departments and civil rights agencies also enforce state-level employment laws.
The Bottom Line
The Peter Principle highlights a common organizational failure mode: rewarding past performance with promotions to roles requiring different skills can produce ineffective leadership. Organizations can minimize this effect by defining role-specific competencies, assessing candidates for the skills a position actually requires, offering alternative career tracks, and supporting promoted employees with training, trial periods, and clear performance metrics. Thoughtful promotion policies protect productivity, reduce turnover, and help organizations keep the “cream” from souring.
