The document discusses the successful implementation of the Dynamic Systems Development Method (DSDM) in the Combat Identification Server (CIDS) project by General Dynamics UK, which resulted in on-time and on-budget delivery within a complex defense environment. The use of DSDM facilitated effective project management by allowing for incremental delivery, requirement trading, and enhancing collaboration among team members, thus bridging traditional divides between customers and suppliers. Lessons learned from the project suggest that such agile project management techniques could inform future projects within the defense sector.
