- 3.2 Sources of project requests
| 3.1 Introduction The first step in the system development life cycle is the identification of a need. This is a user’s request to change, improve or enhance an existing system. Because there is likely to be a stream of such requests, standard procedures must be established to deal with them. The objective of project selection is to determine whether the request is valid and feasible before a recommendation is reached to do nothing, improve or modify the existing system or build anew one. The user’s request form should specify the following 1. User – assigned title of work requested. 2. Nature of work requested 3. Problem definition 4. Date request was submitted 5. Date job should be completed 6. Job objectives – purpose of job requested 7. Expected benefits to be derived from proposed change 8. Input / output description – quantity and frequency of inputs and outputs of proposed change. 9. Requester’s signature, title, department etc. 10. Signature, title, department etc, of person approving the request. The user request identifies the need for change and authorizes the initial investigation. It may undergo several modifications before it becomes final. The success of a system depends largely on how accurately a problem is defined. The user’s request must be communicated if the organization’s personnel and other resources are to be successfully mobilized to build and maintain a viable information system plan. 3.2 Sources of project requests There are four primary sources of project requests. The requesters inside the organization are department managers, senior executives, and systems analysts. In addition, government agencies outside the organization may request information systems projects. Depending on the origin of the request and the reason for it, requesters may seek either completely new applications or changes in existing ones. Download 0.94 Mb. Share with your friends:
