The consulting industry can be segmented accordingly: 1) Management consulting firms (eg McKinsey, Bain, BCG â MBB) 2) One-stop-shop and technology-focused consulting firms (eg Accenture, Deloitte) 3) Niche/boutique consulting firms (eg Mercer HR, Kurt Salmon) 4) Independent consultants (self explanatory)
The top four largest consulting firms, all with a heritage in the accountancy sector, known as the Big Four (Deloitte, PwC, EY and KPMG), hold a combined 40% of the total consulting market. Compared to a decade ago the Big Four firms have significantly increased their market share, through organic growth and dozens of acquisitions.
