Abstract
Publisher Summary This chapter describes a spiral model of software development and enhancement. The spiral model of the software process has been evolving for several years, based on experience with various refinements of the waterfall model as applied to large government software projects. The spiral model can accommodate most previous models as special cases and further provides guidance as to which combination of previous models best fits a given software situation. Development of the TRW Software Productivity System (TRW-SPS) is its most complete application to date. The chapter illustrates the radial dimension that represents the cumulative cost incurred in accomplishing the steps to date and the angular dimension that represents the progress made in completing each cycle of the spiral.
