Cummings Aerospace has tailored our Scrum process to address the more formal waterfall design documentation needs of the typical Department of Defense customer. We determined an acceptable level of tailoring that allows us to deliver robust design documentation while still adhering to the spirit of Scrum methodology. Our Scrum process design modifications were driven by the basic question: What is the purpose of the design document? Let us share our vision of how formal design products and the agility of Scrum can work together to satisfy contractual needs, while facilitating communication across engineering disciplines and software development teams.
