4. Design and Development of DSS
The development process of DSS relates with the long-term business plans of the organizations. DSS requires resources like capital, time and capacity. The end result is information in the form of reports. Most of the organizations do not recognize information as a resource. They see information as a routine necessity. As an organization grows, the information also increases manifold. The DSS plans are developed concurrent to the business plans. An organization of any size deals with numerous pieces of information.

The Decision Support System (DSS) may be developed using following ways:
1. Prototype method
2. Life cycle approach
In the prototype method, initial methods are developed first. Once implemented, the system is refined and modified as per new specifications. This iterative process is followed till the system is accepted by the user.
In life cycle approach, the DSS development is carried out through different phases. The phases are:
Intelligence, Design, Choice, Implementation and Monitoring. The choice of DSS design is decided on the basis of nature of the system and its applications.
