Information technology consulting (IT consulting or business and technology services) is a field that focuses on advising businesses on how best to use information technology to meet their business objectives. In addition to providing advice, IT consultancies often implement, deploy, and administer IT systems on businesses' behalf. This article does not cite its references or sources. ... Outsourcing entered the business lexicon in the 1980s and often refers to the delegation of non-core operations from internal production to an external entity specializing in the management of that operation. ...

The IT consulting industry can be viewed as a three-tier system:

• Professional services firms which maintain large professional workforces and command high bill rates. These firms are increasingly sourcing their employees from low-cost nations.
• Staffing firms, which place technologists in businesses on a temporary basis. These firms are pejoratively known as "body shops". While they are geographically limited by their customers, they can exploit global cost differences by bringing guest workers to their host country. Body Shops are typically distinguished from Consultancies by their commercial practice of pricing service by the day (the input), rather than by the results of their work (the outputs, or deliverables).
• Independent consultants, who function as contractors (also known as "1099"), employees of staffing firms (also known as "W-2"), or as subcontractors in their own right (also known as "Corp-to-corp").

There is a relatively unclear line between management consulting and IT consulting. There are sometimes overlaps between the two fields, but IT consultants often have degrees in computer science, electronics, technology or management of information systems while management consultants often have degrees in accounting, economics, finance or a generalized MBA (Masters in Business Administration). Professional Services are infrequent, technical, or unique functions performed by independent contractors or consultant whose occupation is the rendering of such services. ...
