Despite the availability of numerous "Design for X (DfX)" concepts/methods, their application is challenging for two reasons: • because methods have been developed with different foci (e.g., manufacturing vs. quality), it is difficult to know how different methods complement each other • in what sequence and where at the design stage they should be applied. We address this challenge with a review of DfX methods with recommended design stages for their use from the published literature. We also provide a thematic clustering for their application along with a maturity index for each DfX concept.

“…The DMSMS type obsolescence problem is especially prevalent in 'sustainment-dominated' systems where the cost of sustaining (maintaining) the system over its support life far exceeds the cost of manufacturing or procuring the system (Sandborn and Myers, 2008). Sustainment in this paper refers to three things: keeping the system operational, continuing to manufacture and install versions of the original system that satisfy the original requirements, and finally the ability to manufacture and install versions of the original system that satisfy new and evolving requirements.…”

Technology obsolescence also known as diminishing manufacturing sources and material shortages (DMSMS) is a significant problem for systems whose operational life is much longer than the procurement lifetimes of their constitute components. The most severely affected systems are sustainment-dominated, which means their long-term sustainment (lifecycle) costs significantly exceed the procurement cost of the system. Unlike high-volume commercial products, these sustainment-dominated systems may require design refreshes to simply remain manufacturable and supportable. Design refresh planning (DRP) is a strategic method for reducing the lifecycle cost impact of DMSMS and increasing system availability. The objective of DRP is to determine when a design refresh should occur (or what the frequency of refreshes should be) and how to manage the system components that are obsolete or soon to be obsolete at the design refreshes. This paper describes the formulation and implementation of constraints in the DRP process for systems impacted by DMSMS type obsolescence and proposes a method of transforming an implicit system limitation into an explicit DRP constraint. These constraints can reflect technology roadmap requirements, obsolescence management realities, logistics limitations, budget limitations and management policy.

When an original equipment manufacturer no longer supplies and/or supports a product then the product is considered to be obsolete. Obsolescence is a significant problem for systems whose operational and support life is much longer than the procurement lifetimes of their constituent components. Unlike high-volume, commercial products, which are quickly evolved, long field life, low-volume systems, such as aircraft may require updates of their components and technology called design refreshes to simply remain manufacturable and supportable. However these systems can’t perform design refreshes all the time due to the high nonrecurring and re-qualification costs. One approach to optimally managing this problem is to use DRP (Design Refresh Planning), which is a strategic method for scheduling design refreshes such that the life cycle cost impact of obsolescence is minimized. The planning of these design refreshes is restricted by various constraints, which need to be implemented into the DRP process. These constraints can reflect technology roadmap requirements, obsolescence management realities, logistical restrictions, budget ceilings and management policy. In this paper, constraints imposed on the DRP process are explored, classified within a taxonomy, and implemented in the planning process. A communications system design example is included.
