The primary key in the decision making process is the amount of data collected and how well this data is interpreted. Nowadays, Managers aren’t satisfied by getting direct answers to their direct questions, Instead due to the market growth and increase of clients their questions became more complicated. Questions are like‖ How much profit from selling our products at our different centers per month‖. A complicated question like this isn’t as simple to be answered directly; it needs analysis to three fields in order to obtain an answer.
The Decision making processes
1. Identify information about the problem
2. Analyze the problem
3. Collect and evaluate the information, and define alternative solutions.
The decision making process exists in the different levels of an organization. The speed and the
simplicity of gathering data and the ability to convert this data into information is the main element in the decision process. That’s why the term Business Intelligence has evolved.
