• Scenario Generation and Goal Seeking With a DSS
1. What-If Mode- Developing scenarios for solution with the assistance of information systems DSS
2. Goal-Seeking Mode- Establishing the input factors necessary to achieve specified goals
DSS
Capabilities of Decision Support Systems Capabilities of Decision Support Systems
• Using DSS in the Decision Making Process 1. Intelligence- A search of the environment is made
to find and define the problem or an opportunity 2. Design- Several alternative solutions are
developed 3. Choice- Alternatives are compared
4. Implementation- Solution is implemented and
tracked, and improvements made • Note: Each of these steps may require backing up
to a preceding one to redefined the problem or select a better solution

• Features of DSS 1. Support decision making in ill-structured
situations when problems are not able to be computerized
2. Help to rapidly obtain quantitative results needed to reach a decision
3. Operate in the ad hoc mode to meet the needs of the user
4. Support modification of the models 5. Foster high quality decision making

6. Facilitate the implementation of decisions 7. Support group decision making
8. Be user friendly 9. Give managers the opportunity to better
understand their business

• Limitations of Using Spreadsheets as DSS Models 1. Limited in data handling capabilities
2. Cannot work with large databases 3. Don not allow for the construction of more
complex models 4. Modifications are difficult to keep updated when
used by numerous people Can lock the worksheet to solve this problem
