The Schedule as Independent Variable (SAIV) Process for Acquisition Software-Intensive Systems

In this article, we show how you can use the MBASE process framework to generate a family of acquisition process models for delivering user-satisfactory systems under schedule, cost, and quality constraints. We present the six major steps of the Schedule/Cost/Schedule-Cost-Quality as Independent Variable (SAIV/CAIV/SCQAIV) process using SAIV and a representative Department of Defense (DoD) Command, Control, and Communications Interoperability application as context. We then summarize our experience in using SAIV on 26 University of Southern California electronic services projects, followed by discussions of SAIV/CAIV/SCQAIV application in the commercial and defense sectors, of model application within the DoD acquisition framework, and of the resulting conclusions.
