This ranking was developed using a structured evaluation approach designed to reflect how government and public-sector leaders assess consulting partners in real-world procurement and transformation environments. Firms were evaluated based on demonstrated public-sector experience, depth of government client work across federal, state, local, and international institutions, and the ability to support complex, multi-stakeholder initiatives.
Additional criteria included execution capability across strategy, operations, technology, and change management, as well as evidence of sustained outcomes rather than one-time advisory engagements.
