IT consulting is an industry classification with different functions including strategy consulting, architecture consulting and operation consulting, and IT consulting firms can come from various “tiers” (MBB, Big 4, boutique, etc.).
IT consultants can work as an independent consultant or at consulting firms with others. These firms can range from small, boutique firms that specialize in healthcare to a global network with specific divisions handling the IT industry.
