# Peter Principle > "People in a hierarchy tend to rise to a level of respective incompetence." > — Laurence J. Peter, 1969 ## The core idea In most organizations, people are promoted based on performance in their current role. But the skills that make someone excellent in role N are often different from the skills required in role N+1. The result: people keep getting promoted until they reach a role they're not good at — and then they stay there. Everyone ends up at their level of incompetence. ## Why this happens **Promotion criteria look backward, not forward.** We promote people for what they've done, not what they can do next. A brilliant individual contributor gets promoted to tech lead because they write great code — but tech lead requires communication, delegation, and conflict resolution, not just coding skill. **Different roles require genuinely different skills.** Engineering and management are different jobs. Coding and architecture are different jobs. Building a product and running a product organization are different jobs. The skills don't automatically transfer. **There's no graceful way back.** Once promoted, stepping down feels like failure — for the person and for the organization. So people stay in roles they're not suited for, often becoming unhappy and underperforming. **Organizations often have no alternative path.** If the only path to higher compensation is management, your best individual contributors will keep getting promoted into management
