Information technology consulting (IT consulting, Computer consultancy, Computing consultancy, technology 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.
The IT consulting industry can be viewed as a Four-tier system:
Professional services firms which maintain large professional workforces and command high bill rates.
Staffing firms, which place technologists with businesses on a temporary basis, typically in response to employee absences, temporary skill shortages and technical projects.
Independent consultants, who function as employees of staffing firms (for US tax purposes, employed on “W-2″), or as independent contractors in their own right (for US tax purposes, on “1099″).

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 information systems while management consultants often have degrees in accounting, economics, Industrial Engineering, finance, or a generalized MBA (Masters in Business Administration).
According to the Institute for Partner Education & Development, IT consultants’ revenues come predominantly from design and planning based consulting with a mixture of IT and Business Consulting. This is different from a Systems Integrator in that you do not normally take title to product. Their value comes from their ability to integrate and support technologies as well as determining product and brands.
