The management consulting business has been growing 25-30% for all firms in the last two years. At the Big Four, the total number of partners engaged in strategy, operations, and the top end of digital advisory — areas typically dominated by firms like McKinsey, BCG and Bain — stands close to 300, with consultant numbers at 5,500-6,000. However, the varying number of digital consultants each firm adds to management consulting complicates direct comparisons.
