Do you want to learn more about the largest IT consulting companies in the world? These consulting companies continuously innovate to stay at the top of the competitive tech industry.
IT consulting, also known as IT management consulting, helps businesses solve operations and business problems through information technology. Developing a strong tech infrastructure and keeping it consistent with industry standards and consumer preferences takes a lot of work. So, this is where IT consulting companies come in.
The IT space is very broad and encompasses technology strategy, operations, and even architecture consulting. Most large IT consulting companies cater to several industries while having specific divisions dedicated to each industry, like healthcare, manufacturing, and more. Compare this to smaller firms that typically specialize in a specific sector and dedicate all their resources to helping companies in that market succeed.
Some IT consulting firms even work in-house and offer day-to-day maintenance of the company’s technology systems. However, most of the companies on this list operate as third-party consultants, offering high-level strategy and recommendations to improve technology utilization.
Below you’ll find a list of the largest IT consulting companies in the world. The companies featured below have primary offices in the US, Europe, and India, along with satellite offices across the globe.
