Application of selected software cost estimating models to a tactical communications switching system: tentative analysis of model applicability to an ongoing development program

Abstract

This study analyzes the applicability of software cost estimating models to a tactical information processing system. In particular, the Boehm and Putnam models are used to obtain predictions which are compared to contractor estimates for the TRI-TAC AN/TTC-42 Unite Level Circuit Switch. Factors affecting model performance are also examined. Conclusion address the requirement for more accurate estimation of software project scope and clarification of model input parameter definitions.
