Design Optimization and Manufacturing Transition in Defense Systems: A Case-Oriented Engineering Management Approach

The increasing complexity of defense systems has intensified the need for effective design optimization and seamless transition from engineering development to manufacturing. While advanced design methodologies enable high-performance solutions, the transition to production often reveals gaps related to manufacturability, compliance, and process stability. These challenges are particularly critical in defense environments, where systems must meet stringent reliability, safety, and certification requirements. This study explores the relationship between design optimization and manufacturing transition in defense systems, emphasizing a case-oriented engineering management approach. It examines how optimization strategies, when aligned with production constraints, can enhance system performance while ensuring scalability and compliance. The research highlights the importance of integrating lessons learned, structured decision-making, and cross-functional coordination in managing complex transitions. A key contribution of this paper is the development of an integrated framework that combines optimization methodologies with case-based engineering management practices. This framework enables organizations to bridge the gap between design intent and manufacturing execution, reducing risk and improving efficiency. The findings demonstrate that successful transition processes depend on the alignment of technical, operational, and organizational factors. By adopting a case-oriented approach, organizations can leverage accumulated knowledge to enhance decision-making and achieve more consistent outcomes in defense manufacturing.
