Unformatted text preview: Alphonza Simpson May 2, 2008 Final Exam Mgmt 640 1. • A decision support system (DSS) or tool is one specifically designed to allow business end users (people at all levels of the company below the executive level) to perform computer-generated analyses of data on their own. This system supports exception reporting, stop light reporting, standard repository, data analysis and rule-based analysis. • Model-Driven DSS emphasize access to and manipulation of a model, for example, statistical, financial, optimization and/or simulation models. While data-driven DSS emphasizes access to and manipulation of a time-series of internal company data and sometimes external data. Simple file systems accessed by query and retrieval tools provide the most elementary level of functionality. • Complete Decision Support System: *Note: A problem that is too complex to be solved by only one tool must be broken down. The breaking is down repeatedly until the apparition of sub-problems can be solved by one tool. *NOTE: THE DSS DATABASE IS A COLLECTION OF CURRENT OR HISTORICAL DATA FROM A NUMBER OF APPLICATIONS OR GROUPS DSS DATABASE *Note: In order to design a DSS, we need to know the human decision process. At this stage we can determine either qualitative or quantitative decision-making tools and also determine our problem. Analysis of problem : This breaks down into sub-problems and solutions. Should FSU open a new location in another part of the state? Specification of DSS (with knowledge of existing components): This phase includes the study and consideration of functional requirements.

The questions asked will reflect a sensitivity analysis. *Note: It is the users (decision maker) responsibility to choose the business components to use amongst various tools in the above stage. User Interface *Note: In the above step, the information requested would now be transferred to the user interface in a way that is easily accessed by the user. Remember it is important for the DSS to be adaptive to the user....
