This multiple-case-based dissertation contributes to the stream of literature on the organizational innovation process by examining Critical Chain Project Management (CCPM) as an innovation with the potential to address an important schedule planning and execution performance gap in DOD weapon system development programs. The contextually different Integrated Product Team case studies in DOD’s F/A-22 fighter aircraft weapons system acquisition program are: manufacturing assembly, manufacturing process, test operations, and supplier product development. Rich descriptions of the case studies are developed by the author, a senior Lockheed Martin Aeronautics Company systems engineer in a role that merged participant, observer, change agent and champion (POCAC). Analysis distinguishes between Program and Operational levels of organizational structure and focuses on the innovation process through use of the author-designed Casey Hybrid Innovation Process (CHIP) model based on Rogers’ stages heuristic.
