Process and economic model of component-based software development: a study from Software CALS Next Generation Software Engineering program

This article overviews the Next-Generation Software Engineering program of the Software CALS (Continuous Acquisition and Lifecycle Support) project (SCALS) in Japan and discusses the component-based software process model and its economic model, based on the early study of the project. With this model, it is estimated that component-based software development could reduce the cost by between 50 and 70%.
