Software development methodologies and traditional and modern information systems

Abstract

Considerable discussion exists about the proper methodology for developing software. Some individuals favor a strict step-by-step approach, while others favor rapid prototyping. The extra dimensions of newer information systems such as Decision Support Systems and Expert Systems add to the confusion. Many individuals believe that new systems need new methodologies.This paper surveys the literature to determine current philosophies concerning traditional and modern information systems. Then, a typology which integrates the philosophies into a model useful for selecting an appropriate methodology for the information system task at hand is proposed.
