Executive support systems (ESSs) are specialized deci-
sion support systems designed to meet the needs of senior
management. They serve to indicate issues of importance to
the organization, indicate new directions the company might
take, and help executives monitor the company's progress.
ESSs are typically easy to use, offer a wide range of computer
resources, and handle a variety of internal and external data.
In addition, the ESS performs sophisticated data analysis,
offers a high degree of specialization, and provides flexibility
and comprehensive communications capabilities. An ESS
also supports individual decision-making styles. Some of the
major decision-making areas that can be supported through
an ESS are providing an overall vision, strategic planning and
organizing, strategic control, and crisis management.
