ENABLING ORGANIZATION - DECISION MAKING

Assalamualaikum peeps. We meet again. For today's post I will talk about decision making system. But first we need to know what is a MODEL? 

A model is a simplified representation or abstraction of reality. Decision making information systems work by building models out of organizational information to lend insight into important business issues and opportunities. There are 3 common types of decision making information system used in organization today.

The first is transaction processing system which the basic business system that serves the operational level in an organization. The most common example of TPS is an operational accounting system such as payroll system. 

Next is decision support system, such as BostonCoach's,models information to support managers and business professionals during decision making process. Three quantitative models are typically used by this system, which is sensitivity analysis, what-if analysis, and goal-seeking analysis. 

The last decision making system is executive information systems which is a specialized DSS that supports senior-level executives within organization. Consolidation, drill down, and slice and dice are a few of the capabilities offered by this system.
