- Enterprise-wide DSS
- An enterprise-wide DSS is a DSS that supports a large group of managers in a networked client-server environment with a specialized data warehouse as part of the DSS architecture.
- Evolutionary Design Process
- A systematic process for system development that is recommended for use in creating DSS. A portion of the DSS system is quickly constructed, then tested, improved, and enlarged in systematic steps. This methodology is similar to prototyping and iterative design. See prototyping.
- Exception Reporting
- A reporting philosophy and approach that supports Management by Exception. Reports should be designed to display significant exceptions in results and data. The idea is to "flag" important information and bring it quickly to the attention of managerial users of the report. Exception reporting can be implemented in any type of DSS, but it is particularly useful in Data-Driven DSS and EIS.
- Executive Information Systems (EIS)
- An EIS is a computerized system intended to provide current and appropriate information to support executive decision making for managers using a networked workstation. The emphasis is on graphical displays and an easy to use interface that present information from the corporate database. They are tools to provide canned reports or briefing books to top-level executives. EIS offer strong reporting and drill-down capabilities.
- Executive Support Systems (ESS)
- An ESS is an Executive Information System (EIS) that includes specific decision aiding and/or analysis capabilities.
- Expert Systems
- An expert system is a man-machine system with specialized problem-solving expertise. The "expertise" consists of knowledge about a particular domain, understanding of problems within that domain, and "skill" at solving some of these problems.
