TPS ATA FOR MIS APPLICATIONS
Decision Support S"stem
How managers can enhance their decision making
Introduction
•
The more information you have, based on i
nternal experiences or from external source
s, the better your decisions. Business execu
tives are faced with the same dilemmas wh
en they make decisions. They need the bes
t tools available to help them.
Decision ma,ers to ma,e -ualit" decisions should$ to the
.est of their a.ilities:
1. thoroughly check a wide range of alternatives
2. gather full range of goals and implications of choices
. weigh costs and risks of both positive and negative conse!u
ences
". intensively search for new information for evaluating alterna
tives
#. take all new information into account, even when it doesn$t s
upport initial course of action
%. re&examine positive and negative conse!uences of all altern
atives, including initially re'ected ones
(. make detailed provisions for implementation, including conti
ngency plans for known risks
(ecision Support Systems ((SS$
help executives make better decisions b
y using historical and current data from int
ernal Information Systems and external so
urces. By combining massive amounts of d
ata with sophisticated analytical models a
nd tools, and by making the system easy t
o use, they provide a much better source o
f information to use in the decision-making
process.
