The obsolescence and diminishing manufacturing sources and material shortages, O/DMSMS in short, have consequences on the products architecture and on their desirability, usefulness, or usability. Different strategies are used to mitigate these risks. This paper relies on the possible sources of obsolescence for a focal company. The O/DMSMS could be originated within the company, its supply chain or its environment. The key idea is to explore the propagation of obsolescence and DMSMS throughout the product architecture and its supporting supply chain. By distinguishing obsolescence from DMSMS, it becomes possible to define solutions to deploy to reduce as much as possible their propagation, making the product and its supporting supply chain more resilient. These solutions are the barriers that can be subdivided into Design-for-Resilience and Control-for-Resilience. These concepts are discussed and illustrated through examples. Some conclusions and perspectives are discussed at the end of the paper.
