Define decision support system in your own words. Also illustrate the concept using your organizational context.
A decision support system (DSS) is a computer-based information system that supports business or organizational decision-makingactivities. DSSs serve the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance.
DSSs include knowledge-based systems. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from a combination of raw data, documents, personal knowledge, or business models to identify and solve problems and make decisions.
Typical information that a decision support application might gather and present are:
inventories of information assets (including legacy and relational data sources, cubes, data warehouses, and data marts),
comparative sales figures between one period and the next,
projected revenue figures based on product sales assumptions.
Three fundamental components of a DSS architecture are:[5][6][10][11][12]
the database (or knowledge base),
the model (i.e., the decision context and user criteria), and
the user interface.
The users themselves are also important components of the architecture
Development Frameworks
DSS systems are not entirely different from other systems and require a structured approach. Such a framework includes people, technology, and the development approach.
DSS technology levels (of hardware and software) may include:
The actual application that will be used by the user. This is the part of the application that allows the decision maker to make decisions in a particular problem area. The user can act upon that particular problem.
Generator contains Hardware/software environment that allows people to easily develop specific DSS applications. This level makes use of case tools or systems such as Crystal, AIMMS, and iThink.
Tools include lower level hardware/software. DSS generators including special languages, function libraries and linking modules
An iterative developmental approach allows for the DSS to be changed and redesigned at various intervals. Once the system is designed, it
