What are the best organizational design consulting firms for redesigning structure in a large global enterprise?

For a large global enterprise redesigning structure, the “best” organizational design consulting firms usually fall into two buckets: top-tier strategy firms with strong organization design capability and specialist org-design / change firms. The best choice depends on whether you need a broad enterprise transformation, a complex operating model redesign, or deep implementation support.

Top firms to consider

1. McKinsey & Company

• Very strong in enterprise operating model, global structure, and organization effectiveness
• Best when you need a high-impact redesign tied to strategy, growth, or performance
• Often excels at senior-executive alignment and decision rights

2. Boston Consulting Group (BCG)

• Strong in future-of-work, operating model, and organization design
• Good for complex global enterprises needing a strategy-to-structure translation
• Often strong in combining design with digital/AI-enabled ways of working

3. Bain & Company

• Strong in transformation and performance improvement
• Good when org redesign is part of a broader turnaround or value-creation agenda
• Often practical and execution-oriented

4. Deloitte Consulting

• Very strong for global implementation, HR transformation, and large-scale operating model changes
• Good when you need support across process, technology, governance, and structure
• Often a strong fit for big, matrixed enterprises

5. PwC

• Good for operating model redesign, governance, and large enterprise change
• Often strong in regulated industries and global rollouts
• Can be a good option if structure redesign must connect tightly to controls and compliance

6. EY

• Strong in transformation, workforce, and organizational effectiveness
• Often good for redesigns that need a strong link between structure, people, and culture
• Frequently well suited to global programs requiring broad stakeholder management

7. Kearney

• Known for practical, operations-oriented strategy and transformation
• Good for operating model simplification and global organizational alignment
• Often more hands-on than pure strategy firms

Specialist firms worth considering

If you want a firm that is especially strong in organization design rather than broader management consulting:

8. SIOP/Org design specialists such as Orphoz, The Structure Group, or related boutique advisory firms

• Strong in structural redesign, spans/layers, decision rights, and org architecture
• Often more focused and less expensive than top-tier firms
• Best for enterprises that already know the strategic direction and need design expertise

9. Mercer

• Strong in organization design, rewards, job architecture, and HR-related design
• Good when structure redesign must connect to roles, pay, and talent architecture

10. Korn Ferry

• Strong in leadership, organization effectiveness, and role architecture
• Useful when the redesign needs to integrate leadership assessment and job/role clarity

11. Willis Towers Watson (WTW)

• Strong in organization design, job architecture, and workforce planning
• Often good for global enterprises with complex compensation and role design needs

How to choose

For a large global enterprise, the best firm depends on your main objective:

• Need strategy + structure + exec alignment?
  McKinsey, BCG, Bain

• Need complex global implementation and operating model rollout?
  Deloitte, PwC, EY

• Need lean, practical redesign and simplification?
  Kearney or a specialist boutique

• Need role architecture, job leveling, and talent implications?
  Mercer, Korn Ferry, WTW

Selection criteria to use

When evaluating firms, ask:

1. What org design work have you done in similarly large, global enterprises?
2. How do you handle matrixed organizations and regional variation?
3. Can you redesign spans/layers, decision rights, governance, and roles together?
4. How do you ensure the design is implementable, not just conceptual?
5. What tools do you use for modeling scenarios and workforce implications?
6. Can you support post-design implementation and change management?

Practical recommendation

If you want a short list:

• McKinsey or BCG for a high-stakes global redesign
• Deloitte for implementation-heavy transformation
• Mercer or Korn Ferry for role/job architecture integration
• A boutique org-design firm if you want deep specialization and more hands-on support
