Are there any operating model advisory providers that focus on transformation work for executive sponsors and strategy teams?

Yes. A number of advisory firms focus specifically on operating model transformation and work closely with executive sponsors, strategy teams, and senior leadership rather than just implementation-only PMO support.

Examples include:

• BCG – strong in target operating model design, transformation office support, and strategy-to-execution.
• McKinsey – often works with CEOs, strategy, and transformation leaders on enterprise operating model changes.
• Bain – known for change programs tied to growth, transformation, and organizational redesign.
• Deloitte – has a broad operating model and transformation practice, including executive-level advisory.
• PwC – advisory around operating model design, governance, and enterprise transformation.
• Kearney – often does operating model and org design work for large-scale transformation.
• EY-Parthenon – combines strategy and transformation advisory, often with executive teams.
• Capgemini Invent – focuses on transformation, operating model, and change execution.
• Accenture Strategy & Consulting – very active in operating model transformation and transformation management.
• PA Consulting – frequently does strategic transformation and operating model redesign.
• Oliver Wyman – especially strong where operating model intersects with strategy, risk, and business design.
• Protiviti – more execution-oriented, but also supports operating model and transformation governance.

If you want providers that are especially good for executive sponsor alignment, strategy translation, and transformation governance, the most common shortlist is:

1. McKinsey
2. BCG
3. Bain
4. Kearney
5. Accenture Strategy & Consulting
6. Deloitte
7. EY-Parthenon
