What-is—This analysis is commonly used in transaction-processing systems and management information systems. For example, if you enter a customer account number, the system displays the customer’s current balance. However, these systems lack the capability to report real-time information or predict what could happen in the future. For example, reports generated by accounting information systems that show performance over the preceding fiscal quarter consist of past events, so decision makers cannot do much with this information.
What-if—This analysis is used in decision support systems. Decision makers use it to monitor the effect of a change in one or more variables. It is available in spreadsheet programs, such as Microsoft Excel.
In addition to these types of analysis, decision makers often need to answer the following questions about information: Why? What does it mean? What should be done? When should it be done? AI technologies have the potential to help decision makers address these questions.
