Abstract:
Legacy programs have historic ‘baggage’ from years (if not decades) of Integration and Verification (I&V) efforts.  Quite often as new features and functions are added to a legacy system, the new testing is just added to the existing testing backlog and little is rarely done to clean out the testing backlog and approach the I&V efforts more holistically.  Recently on the Cooperative Engagement Capability Program, we analyzed our current processes and using the tenets of Agile (like ‘Continuous Deployment’ and ‘Development Pipeline’) and DevSecOps we redistributed I&V throughout the program development life cycle.  This article provides insight into the five fundamental changes we made to our system to increase test coverage while decreasing overall life cycle cost.  This is not a paper about a revolutionary new Agile process, but it is about how legacy systems can be transformed through the application of Agile concepts and processes.
