What is PAEI? 

The PAEI model, proposed by Adizes, describes the four key roles which make up a successful management team:

• Producer
• Administrator
• Entrepreneur
• Integrator

And is a method to evaluate the contribution and areas of strength of each member of a team. 

What are the Situational Factors? 

The importance of each role in the PAEI model is determined by situational factors, such as:

• Organization type,
• Size of the organization,
• External environment of the organization,
• Stage of development of the organization.
