15/25

Introduction

The more information you have, based on internal experiences or from external source

s, the better your decisions. Business executives are faced with the same dilemmas when they make decisions. They need the best tools available to help them.


16/25

Decision ma,ers to ma,e -ualit" decisions should$ to the

.est of their a.ilities:

1. thoroughly check a wide range of alternatives2. gather full range of goals and implications of choices

. weigh costs and risks of both positive and negative conse!uences

". intensively search for new information for evaluating alternatives

#. take all new information into account, even when it doesn$t support 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 contingency plans for known risks


17/25

ecision Support Systems (SS$

help executives make better decisions by using historical and current data from internal Information Systems and external sources. By combining massive amounts of d

ata with sophisticated analytical models and tools, and by making the system easy to use, they provide a much better source of information to use in the decision-makingprocess.
