Specializations 

Management consulting refers generally to the provision of business consulting services, but there are numerous specializations, such as information technology consulting, human resource consulting, virtual management consulting and others, many of which overlap, and most of which are offered by the large diversified consultancies listed below. So-called "boutique" consultancies, however, are smaller organizations specializing in one or a few of such specializations. 

Current state of the industry 

Management consulting has grown quickly, with growth rates of the industry exceeding 20% in the 1980s and 1990s. As a business service, consulting remains highly cyclical and linked to overall economic conditions. The consulting industry shrank during the 2001-2003 period, but has been experiencing slowly increasing growth since.
