CEO’s Question:
Why do great performers sometimes fail when promoted to a managerial position?
Why This Question Matters
Most CEOs can point to at least one example. A high performer is promoted with the best of intentions. They know the work. They deliver results. They are respected by their peers.
And then the promotion does not work.
Performance declines. Frustration increases. The organization hesitates, hoping things will improve. Sometimes they do. Often they do not.
This pattern is so common it has a name.
The Peter Principle
The Peter Principle was first described by Laurence J. Peter, who observed that people tend to be promoted based on success in their current role until they reach a role where they are no longer effective.
In simple terms, people are promoted to their level of incompetence.
This is not because people suddenly become less capable or less committed. It happens because the complexity of the work increases, and the capability required to do that work also increases.
As long as someone continues to perform well, they are promoted. Eventually, they reach a level where the complexity of the role exceeds their problem-solving capability. At that point, they struggle.
In very large organizations, people can sit at that level for years, doing suboptimal work. Smaller and owner-led organizations cannot afford that. Every role matters too much.
The good news is that the Peter Principle is not inevitable.
Fit to Role Is Not One Thing
The reason the Peter Principle persists is that organizations oversimplify what fit to role really means.
Fit to role has three distinct dimensions, and all three must be present at the same time for someone to be effective.
When even one is missing, performance suffers.
Dimension 1: Problem-Solving Capability
Problem-solving capability is about a person’s ability to handle the complexity of work in the role.
As we explored in earlier articles, complexity increases as the time horizon extends and as problems become less structured. Moving from individual contributor work into a management of former peers always requires a step change in how problems are processed.
This is why strong performers often struggle after promotion. They are still capable, but their capability may be well matched to their previous role, not the new one.
This is the core mechanism behind the Peter Principle.
Dimension 2: Skills and Knowledge
Skills and knowledge are the most visible and easiest dimension to assess.
This includes technical expertise, professional training, and learned managerial skills. Organizations tend to rely heavily on this dimension when making promotion decisions because it feels objective and measurable.
But skills and knowledge alone are not enough. Someone can be highly skilled and still fail if they lack the capability to deal with the level of complexity in the role, or if they do not apply themselves fully to the work.
Skills and knowledge have three distinct aspects.
The first is knowledge, which includes understanding the business, the systems, and the context in which the work is done.
The second is technical skills, which are the learned abilities required to apply that knowledge effectively, whether that involves analysis, planning, financial acumen, or operational expertise. one can think of this as the demonstrated capability to apply knowledge in an effective way.
The third is social processing skills, which enable a manager to work through others by communicating clearly, listening well, resolving conflict, and building alignment. All three are necessary.
Strong knowledge without technical skill limits execution, technical skill without social processing limits leadership, and social skill without sufficient knowledge undermines credibility.
Dimension 3: Application and Valuing the Work
This dimension is often overlooked.
Application is about whether a person values the work of the role. Some people genuinely enjoy managerial work. Others do not.
Someone may be capable of managing and have the required skills, but if they do not value planning, coaching, delegation, and accountability, they will avoid those activities. They may retreat into technical work, micromanage, or disengage.
When people do not value the work, they do not apply their full capability to it.
This is not a character flaw. It is a mismatch between the person and the role.
Solving the Peter Principle in Practice
Solving the Peter Principle requires changing how organizations think about promotion.
Promotion should not be a reward for past performance. It is a decision about future work.
That decision must consider:
- The level of complexity in the role
- The person’s problem-solving capability
- Their skills and knowledge
- Whether they value the work and will apply themselves to it
When all three dimensions align, people thrive. When they do not, performance declines, regardless of good intentions.
What This Means for CEOs
Fit to role is not a people problem. It is a system design issue.
CEOs are accountable for ensuring that roles are clearly defined and that promotion decisions are made with all three dimensions in mind. When this discipline is in place, organizations avoid costly missteps, build stronger leadership pipelines, and dramatically improve execution.
The Peter Principle is not a law of nature. It is a symptom of poor role design and incomplete assessment.
A Final Thought
Great performers do not fail because they were promoted. They fail because the organization did not fully understand what the next role required.
I explore this concept in much greater depth in my book, The Effective CEO: The Balancing Act that Drives Sustainable Performance, where I outline practical ways to design roles, assess fit, and build organizations that work.
