System Development and Project Management

Abstract

Nearly all information systems developments follow a structured approach. This is true of all projects. This chapter takes a critical look at both system development and project management. The development of computer systems is a complex process, one with many opportunities for things to go wrong. To try and control this complex process, a methodology was required that would bring more discipline to the computer system development process. There was a need to make more efficient use of the resources that were available. However, the use of accepted methodologies for system development has not guaranteed the successful implementation of information systems. There are still weaknesses in the traditional methodologies. This section examines some relevant current literature regarding the system development process and identifies areas of weakness that could be improved. In the UK the National Computing Centre in Manchester defined the system development process as a number of stages. Seven were identified: feasibility study; systems investigation; systems analysis; systems design; systems development; implementation; and review and maintenance. These stages were later revised but are still generally viewed as the key elements of the computer system development process. This defines the development process as a technical one. Many methodologies that have adopted this type of approach have become grouped under the heading of ‘hard systems methodologies’. This structured approach has proved popular with IS/IT professionals since it caters for their needs as technical staff who view information system development as systematic problem-solving. It is not surprising that some authors have a narrow view of what is entailed in the system development process. Some regard it as simply structuring hardware and software to achieve effective and efficient processing of the information system.
