What Is The PAEI Model? The PAEI Model In A Nutshell

The PAEI model was developed by Yugoslavian-American business consultant Dr. Ichak Adizes in the 1970s. The PAEI model is a framework defining four management roles that perform key functions within an organization through four roles: the producer, the administrator, the entrepreneur, and the integrator.

Understanding the PAEI model

Adizes argued no single manager could properly meet the needs of their organization or department. In other words, it was impossible for a leader – no matter how great – to embody multiple roles at the same time.

Instead, Adizes suggested effective management required a team of leaders working in harmony and using their collective knowledge to tackle the most complex issues or challenges.

The PAEI model helps leaders benefit from their natural strengths while identifying areas for improvement.

Furthermore, it increases collaboration as leaders learn to communicate more effectively with those embodying different leadership styles.

The four roles of the PAEI model

The PAEI model is an acronym of four management roles specified by Adizes and critical to organizational success:

The Producer

Organizations exist to produce results aligned with meeting customer needs.

The Producer tends to be highly delivery-focused, working long hours in the belief that hard work is the answer to everything.

Since they consider themselves irreplaceable, they have a hard time delegating responsibility to others.

The Administrator

While the Producer focuses on what to do, the Administrator is concerned with how things get done.

They tend to focus on controlling, organizing, planning, and scheduling activities by focusing on processes, procedures, and systems.

The Entrepreneur

As the name suggests, the Entrepreneur is a visionary and innovative thinker that inspires those around them.

They are less risk-averse than other management roles because they believe in their vision and are comfortable with uncertainty. 

The Integrator

These leaders are warm, caring, trustworthy, and reliable.

They are more concerned with developing people and teams to make the organization more efficient and enhance company culture.

Advantages of the PAEI model

Management styles have been studied for over a century, producing a diverse range of management frameworks.

However, the PAEI model has some distinct advantages:


The model is simple, concise, easily understood, and can be applied by every member of an organization – regardless of whether they are a frontline worker or CEO.


The model can be used to assess or analyze a leader, group, or company.

It can also be incorporated into project and product management.


Practitioners of the PAEI model note that it encapsulates an accurate representation of how leaders function or behave in the workplace.

Key takeaways:

  • The PAEI model is a framework defining four management roles that perform key functions within an organization. It was developed by business consultant Dr. Ichak Adizes in the 1970s.
  • The PAEI model is an acronym of four management roles: the Producer, the Administrator, the Entrepreneur, and the Integrator. Organizational success can only occur when leaders embodying one style learn to communicate with those embodying a different style.
  • The PAEI model is one of many management frameworks. However, practitioners enjoy the model because it is simple to understand, versatile, and accurate.
