>It's just I note this is a DOD document, and I don't think we should be designing jet fighters in 2 week sprints. Airframes probably can't be modified like that. So it follows that, within a waterfall project, the flight software shouldn't be developed agile either. There are some linked documents at the end of the OP, and this one with link "to be added"[0]. It addresses your exact point, in that hardware development and software development have to move in completely different processes. Their first example is the DoD 5000 process[1] and how it is a total fail for software: "The DoD 5000 process , depicted on the left, provides a detailed DoD process for setting requirements for complex systems and ensuring that delivered systems are compliant with those requirements. The DoD’s “one size fits all” approach to acquisition has attempted to apply this model to software systems, where it is wholly inappropriate. Software is different than hardware. Modern software methods make use of a much more iterative process, often referred to as “DevOps,” in which development and deployment (operations) are a continuous process, as depicted on the right. A key aspect of DevOps is continuous delivery of improved functionality through interaction with the end user." "DoD 5000 is designed to give OSD, the Services, and Congress some level of visibility and oversight into the development, acquisition, and sustainment of large weapons systems. While this directive may be useful for weapons systems with multi-billion dollar unit costs, it does not make sense for most software systems."
