Mintzberg's Organizational Structures
Also known as: Mintzberg's Configurations, Five Organizational Forms
A typology of five (later seven) organizational configurations — Simple Structure, Machine Bureaucracy, Professional Bureaucracy, Divisionalized Form, and Adhocracy — based on how organizations coordinate work and which part of the organization dominates.
Quick Reference
Memory Aid
Five structures: Boss decides (Simple), Rules decide (Machine), Pros decide (Professional), Divisions decide (Divisionalized), Teams decide (Adhocracy).
TL;DR
Match your organizational structure to your coordination needs: direct supervision for simple work, standardized processes for efficiency, professional skills for expertise, outputs for diversity, mutual adjustment for innovation.
What Is Mintzberg's Organizational Structures?
Mintzberg identified five basic ways organizations can be structured, each suited to different environments. A startup is a Simple Structure. A factory is a Machine Bureaucracy. A hospital is a Professional Bureaucracy. A conglomerate is Divisionalized. An innovation lab is an Adhocracy.
Against Management Fashion
Management is a curious phenomenon. It is generously paid, enormously influential, and significantly devoid of common sense.
— Henry Mintzberg, Managing
Every organization consists of five parts: the Strategic Apex (top management), Middle Line (middle managers), Operating Core (people doing the work), Technostructure (analysts who standardize), and Support Staff. Different configurations emerge based on which part dominates and which coordination mechanism is primary. The right configuration depends on the organization's age, size, environment, and technology.

Origin & Context
Published in 'The Structuring of Organizations' and later refined in 'Structure in Fives.' Mintzberg synthesized decades of organizational theory into a practical typology.
Core Components
Simple Structure
Direct supervision from the top. Small, flexible, centralized.
Example
A founder-led startup where the CEO makes most decisions directly.
Machine Bureaucracy
Standardized work processes. Large, efficient, formal.
Example
McDonald's: every process is standardized, documented, and repeatable worldwide.
Professional Bureaucracy
Standardized skills. Professionals with high autonomy.
Example
A hospital: doctors, nurses, and specialists trained through standardized education, then given autonomy in practice.
Divisionalized Form
Standardized outputs. Semi-autonomous divisions with corporate oversight.
Example
Procter & Gamble: each brand operates semi-independently, measured on financial outputs.
Adhocracy
Mutual adjustment. Organic, innovative, project-based.
Example
A design consultancy like IDEO: flexible teams forming around projects, dissolving when done.
Mintzberg originally identified five configurations in 1979, but later expanded to seven by adding the Missionary Organization (driven by ideology and shared beliefs, like some nonprofits and religious organizations) and the Political Organization (driven by internal power struggles with no dominant coordination mechanism).
When to Use Mintzberg's Organizational Structures
Organizational redesign
Problem it solves: Helps leaders choose the right organizational structure based on their strategy and environment.
Real-World Application
A company transitioning from a single product to a multi-product portfolio used Mintzberg to recognize it needed to shift from Machine Bureaucracy to a Divisionalized Form.
Diagnosing structural dysfunction
Problem it solves: Identifies when the organizational structure doesn't fit the work being done.
Real-World Application
A software company with Machine Bureaucracy processes (heavy approvals, standardized workflows) struggled to innovate. Mintzberg's framework helped them see they needed Adhocracy structures for their R&D teams.
Most organizations are hybrids. Use Mintzberg's types as diagnostic lenses, not rigid categories. Ask: which configuration does each part of our organization most resemble?
How to Apply Mintzberg's Organizational Structures: Step by Step
Before You Start
- →Understanding of the organization's strategy and environment
- →Knowledge of how work is actually coordinated (vs. how the org chart says it should be)
Identify the Dominant Configuration
Assess which of the five configurations most closely matches your current organization.
Tips
- ✓Look at how work is actually coordinated, not how the org chart is drawn
Common Mistakes
- ✗Confusing the formal structure with the actual coordination mechanism
Assess Fit with Strategy and Environment
Determine whether the current configuration fits your strategic needs.
Tips
- ✓Stable environments suit bureaucracies; dynamic environments suit adhocracies
Common Mistakes
- ✗Assuming one configuration is universally 'best'
Identify Structural Tensions
Look for mismatches between the configuration and the work requirements.
Tips
- ✓Different parts of the organization may need different configurations
Common Mistakes
- ✗Applying one configuration to the entire organization
Design the Target Structure
Choose the configuration that best fits your strategy and design accordingly.
Tips
- ✓Consider hybrid structures where different units use different configurations
Common Mistakes
- ✗Copying another organization's structure without considering context
Value & Outcomes
Primary Benefit
Provides a clear typology for understanding which organizational structure fits which strategic context.
Additional Benefits
- ✓Explains why structural changes fail when they don't fit the coordination mechanism
- ✓Helps leaders design hybrid structures for complex organizations
What You'll Learn
- →How different coordination mechanisms create different organizational forms
- →How to match organizational structure to strategy and environment
Typical Outcomes
Best Practices
📋 Preparation
- •Study how work is actually coordinated, not just the formal structure
- •Assess the environment's stability and complexity
🚀 Execution
- •Consider hybrid configurations for different units
- •Align coordination mechanisms with the type of work being done
🔄 Follow-Up
- •Monitor for drift toward Machine Bureaucracy
- •Adjust structure as strategy and environment evolve
💎 Pro Tips
- •The best organizations deliberately use different configurations for different parts: Adhocracy for R&D, Machine Bureaucracy for operations, Professional Bureaucracy for specialized services
Organizations naturally drift toward Machine Bureaucracy as they age and grow. Leaders must consciously resist this drift if their strategy requires innovation and flexibility.
NASA's Structural Evolution
NASA's history illustrates Mintzberg's configurations in action. During the Apollo era, it operated as an Adhocracy — flexible project teams innovating under intense pressure. As it matured, it drifted toward Machine Bureaucracy with standardized processes and heavy documentation. The Challenger and Columbia disasters were partly attributed to this bureaucratic drift stifling the open communication that had characterized the Adhocracy years.
Limitations & Pitfalls
Typology is simplistic for complex, modern organizations
Mitigation: Use as a diagnostic starting point and combine with other organizational design tools
Does not address digital and networked organizational forms
Mitigation: Extend with platform and ecosystem thinking for modern contexts
