The system engineering function writes a system engineering plan following the SEP document requirements definition, builds it with input from, and the constraints of, project management, product assurance, the engineering disciplines, production, and the operations and logistics teams, and ties it to the lower-level plans so that all of them stay consistent with one another. The plan's content grows with the project: risk and new technology early on, verification and validation later.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
