Abstract:

This paper summarizes the experiences of the software requirements team on the Command Center Processing and Display System Replacement CCPDS-R program. The CCPDS-R program involves the development of large amount of command and control software while using a new approach to the entire software development process. The major challenges that the software requirements team faced include performance constraints, dealing with uncertainty in a fixed price development environment, and incompatibility of the required deliverable documentation as specified in DOD-STD-2167 with real project needs. The techniques included a small team with good tools, concurrent software development, extensive prototyping and performance modeling, and DID tailoring. The focus of this paper is on the process, techniques and tools that supported the critical front end of a successful large scale Ada development program.
