SAD13-Needs Identification

The success of a system depends largely on how accurately a problem is defined, thoroughly investigated and properly carried out through the choice of solution. Needs identification and analysis are concerned with what the user needs rather than what she wants. The analyst starts to think of the solution for the problem only after it has been identified, defined and evaluated. This helps the user and the analyst understand the real problem rather than its symptoms.

The user or the analyst may identify the need for a candidate system or enhancements in the existing system. The user initiates an investigation by filling out a request form for information. The request contains the objectives and expected benefits. (See figure  – A sample user’s request form). Thus for the design of a successful system, a clear knowledge of the system is essential. This information is given out in needs identification.
