An MIS has three components: (a) an internal records
system, which includes information on the order-topayment
cycle and sales information systems; (b) a
marketing intelligence system, a set of procedures
and sources used by managers to obtain everyday information
about pertinent developments in the marketing
environment; and (c) a marketing research system
that allows for the systematic design, collection,
analysis, and reporting of data and findings relevant to
a specific marketing situation.
