Consulting is about helping organisations in the private, public and social sector solve big problems and improve their performance.
This might involve businesses figuring out how to grow, governments figuring out how to scale and humanitarian organisations figuring out how to deliver impact.
Traditionally the large strategy consulting firms (McKinsey, BCG and Bain (collectively referred to as MBB)) focused heavily on strategy. However, now the industry has shifted to encompass data analytics, design work, implementation and transformation, and restructuring distressed companies.
