Mintzberg identified different organizational configurations that mix the five building blocks, suggesting the most suitable configuration depends on the complexity of the work.

• Simple Structure
• Machine Bureaucracy
• Divisionalized Form
• Adhocracy

1. Simple Structure
   • Found in entrepreneurial companies.
   • The strategic apex exercises direct control over the operating core, with no middle line.
   • There is little or no support staff or technostructure.
   • This structure is very flexible and can react quickly to changes because the strategic apex controls the operating core directly.
2. Machine Bureaucracy
   • The technostructure is the dominant element.
   • The entity is controlled and regulated by the bureaucracy, with an emphasis on control through regulations.
   • It is difficult for this type of organization to react quickly to environmental changes, making it more suitable for stable business environments.
3. Divisionalized Form
   • The middle line is dominant, characterized by powerful executive managers.
   • The organization structure is divisionalized, each division led by a divisional manager.
   • Divisional managers can be powerful and restrict the influence of the strategic apex on decision-making.
4. Adhocracy
   • This type of organization has a complex, disordered structure, using teamwork and project-based work.
   • It is found in complex, dynamic environments where innovation is essential for success.
   • External consultancies and experts may play a role, making the support staff element very important.

Differences Between Configurations:
The differences between these four organizational configurations can be highlighted as follows:

Each configuration supports the change management process differently, depending on how it coordinates its processes and responds to environmental factors.
