ESS address nonroutine decisions requiring judgment, evaluation, and insight because there
is no agreed-on procedure for arriving at a solution.
ESS provide a generalized computing and communications capacity that can be applied to a
changing array of problems.
ESS are designed to incorporate data about external events, such as new tax laws or
competitors, but they also draw summarized information from internal MIS and DSS.
ESS are designed for ease-of-use and rely heavily on graphical presentations of data.
