The Custom Consulting Company (CCC) places temporary computer
professionals in companies that request such employees. CCC's business
can be explained as follows:
CCC keeps a list of professionals willing to work or currently working on a
temporary assignment. A professional may have up to three qualifications,
including programmer, senior programmer, analyst, tester, designer, and so
on. A company always requests a professional with a single specific quali-
fication. CCC keeps a list of all its clients (that is, a list of other companies)
and their current needs. If CCC can find a match, a professional with the
required qualification is assigned to a specific opening at one of CCC's
clients.
