Obsolescence issues in complex product lifecycles can cause disruptions in projects, leading to delays in project schedules, significant costs, and loss of prestige, particularly in defense companies. This article aims to address the obsolescence management issues of electronic components in complex product lifecycles in the defense industry with a new framework called the "Shell Structure". The Shell Structure acts as a shield that safeguards and reinforces electronic components involved in every phase of the product lifecycle from obsolescence problems. The Shell Structure consists of five main processes: project management, research and development, manufacturing and services, supply chain management, and the new obsolescence management process. A new overarching obsolescence management process integrated into these main processes have been designed, specifically tailored for a large-scale defense industry company, using a process map example. The main obsolescence management process encompasses three subprocesses: the development of obsolescence management plan, the development of obsolescence management strategies, and the monitoring of obsolescence management plan. These processes interact in real-time, ensuring that electronic component data flows seamlessly in the context of digitalization utilizing Complex Event Processing System architecture. The obsolescence management-focused framework fosters interdisciplinary collaboration among the main processes of defense companies through the Shell Structure.
