Abstract
The Information Systems Development Life Cycle (ISDLC) is usually treated as a rigid sequence of activities. This article asserts that differences in the nature of development projects should affect the planning of the ISDLC. Two classes of factors affecting the ISDLC are identified: factors relating to the environment and factors relating to the development effort (e.g., inhouse development vs. canned software package). Each step along the ISDLC is decomposed into several dimensions relating to the activities that should be performed, the degree of control that should be exerted, to human resources, to other resources, and to the time factor. The relationship between the six dimensions and the two classes of factors are explained. Finally, a practical approach to ISDLC planning is suggested based on a structured procedure and a number of working forms. It assists in preliminary planning of the development process as well as in periodic reviews and revisions whenever the project reaches a certain milestone.
Journal Information
The editorial objective of the MIS Quarterly is the enhancement and communication of knowledge concerning the development of IT-based services, the management of IT resources, and the use, impact, and economics of IT with managerial, organizational, and societal implications. Professional issues affecting the IS field as a whole are also in the purview of the journal.
Publisher Information
Established in 1968, the University of Minnesota Management Information Systems Research Center promotes research in MIS topics by bridging the gap between the corporate and academic MIS worlds through the events in the MISRC Associates Program.
