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.
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 are self-employed or who function as employees of staffing firms (for US tax purposes, employed on Form W-2), or as independent contractors in their own right (for US tax purposes, on “1099”).

There are different reasons why consultants are called in:
To gain external, objective advice and recommendations
To gain access to the consultants’ specialized expertise
Temporary help during a one-time project where the hiring of a permanent employee(s) is not required or necessary
To outsource all or part of the IT services from a specific company.
