Decision support systems are interactive software-based systems intended to help managers in decision making by accessing large volume of information generated from various related information systems involved in organizational business processes, like, office automation system, transaction processing system etc.
DSS uses the summary information, exceptions, patterns and trends using the analytical models. Decision Support System helps in decision making but does not always give a decision itself. The decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.
Programmed and Non-programmed Decisions
There are two types of decisions - programmed and non-programmed decisions.
Programmed decisions are basically automated processes, general routine work, where:
These decisions have been taken several times
These decisions follow some guidelines or rules
For example, selecting a reorder level for inventories, is a programmed decision
Non-programmed decisions occur in unusual and non-addressed situations, so:
It would be a new decision
There will not be any rules to follow
These decisions are made based on available information
These decisions are based on the manger's discretion, instinct, perception and judgment
For example,investing in a new technology is a non-programmed decision
Decision support systems generally involve non-programmed decisions.Therefore,there will be no exact report,content or format
