IBM Global Business Services

IBM Global Business Services (GBS) is the professional services arm of Global Services, including management consulting, systems integration, and application management services. It is the world's largest IT consultancy Services.GBS is also the highest revenue earning division of IBM.


The beginning of IBM’s involvement in IT services can be traced back at least to 1989 when Eastman Kodak Company and IBM completed an agreement by which IBM designed, built and managed a new state-of-the-art data center for Kodak in Rochester, New York.

Also in 1989, IBM introduced Business Recovery Services, an offering that enables a business to continue operations in the event of an unplanned outage or disaster.

In 2002, IBM Global Services acquired the management consulting and technology services arm of PricewaterhouseCoopers, around the same time the other Big Four accounting firms were selling off their consulting arms (this was from intense pressure to avoid conflicts of interest in light of the Sarbanes-Oxley Act). PwC's consultancy business was sold to IBM for approximately US$3.9 billion in cash and stock. This nearly doubled the number of consultants within IBM Global Services, adding 30,000 consultants in 52 countries.
