Western Europe Top 10 IT Services Vendors, 2015: Growth of the New, Decline of the OldThis IDC study analyzes the 2015 revenues of the 10 largest IT services vendors and compares them against market trends. Furthermore, this study looks at the top 10 vendors' market shares in the total IT services market as well as in project-oriented services, outsourcing, and support services (including IT education and training). "The top 10 IT services vendors with a large share of project services — specifically application services — performed better than the average in 2015," said Mette Ahorlu, research director, IDC European Services. "Accenture and Deloitte both had double-digit growth, which merited Deloitte's entrance to the top 10 this year. Vendors with high exposure to the slow-growth infrastructure services market generally performed poorly. The combined market share of the top 10 dropped 0.4 percentage points — in net terms, this market share loss was captured by the India-based vendors (India Inc.), which continue to take market share from the top 10 and the vendors just below the top 10."
