Abstract

A project is undertaken to meet specific needs and goals or problems. One most know what the problem is before it can be solved. The basis for a candidates system is recantation of need for improving an information system or a procedure. For example a supervisor may want to investigate the system flow in purchasing, or a bank president has been getting complaints about the long lines in the drive-in. This need leads to system that can solve the problem. It entails looking into the duplication of effort.

If the problem is serious enough, management my want to have an analyst look at a preliminary survey or an initial investigation to determine whether an alternative it is possible. Such an assignment implies a commitment, especially if the analyst is hired from the outside. In the larger environments, where formal procedures are the norm, the analyst's first task is to prepare a statement specifying the scope and the objective of the problems.

The idea for changes originates in the environment or from within the firm. Environment based ideas originate from the customers, vendors, government sources, and the like. For example, new unemployment compensation regulations may make it necessary to change the reporting procedure, format and contents of various reports as well as file structures. Customer complaints about the delivery of orders may prompt an investigation of the delivery schedule, the experience of truck drivers, or the volume of orders to be delivered. When investigated, each of these ideas may lead to a problem definition as a first step in the system life cycle process.
