Tri-Cycle: a prototype methodology for advanced software development

The use of prototyping is considered in the context of advanced military computing projects. One concern is the lack of a formal control process to monitor progress. To address this concern, a software development methodology is proposed that integrates evolutionary prototyping techniques and traditional planning and review activities. The methodology, Tri-Cycle, prescribes a framework that promotes a disciplined approach to better plan, monitor, and evaluate software development without impeding development progress. Early versions of the methodology are being integrated into existing projects. These versions have been well received by customers
