The B4 organization at National Security Agency (NSA) prepares all of the Independent Cost Estimates for major NSA Acquisitions. NSA has been developing most of its software utilizing Agile development practices since approximately 2005. Around 2014 the development processes began to transition to a DevOps process. This change has required changes to the estimation workflows and processes that B4 had been utilizing for the estimation of Agile projects. This presentation will first provide a brief discussion of what Agile and DevOps are. Where they are the same and what the differences are. It will then discuss what changes to the estimation workflow and processes have been required to support DevOps estimation. Finally, the implications these changes will have on the once and future COCOMO models: Size inputs, Tools, Activity and Resource models, Testing.
