Top 10 IT Consulting Firms

What does an IT consulting firm do? An IT consulting firm advises businesses about how to best use information technology to optimize processes and create value. Firms also recommend how to carry out digital transformations that bring the technological capabilities of a company up to speed.

IT consulting firms can be divided into three groups: the major international players that specialize in IT consulting, the large generalist firms that have an IT consulting practice internally, and niche firms that focus on a specific market or discipline. Working in IT consulting, consultants often confer with staff across the client organization, analyze data, determine information system requirements, define project objectives, and make recommendations for appropriate software and hardware systems. Career progression for IT consultants follows a traditional consulting structure: Associate > Consultant > Manager > Partner.
