Programs are generally unaware of risks for a material obsolescence lurking within the supply chain and by the time that the issue impacts an item, precious time may have been lost. This presentation will discuss several steps that a program can take to: (1) identify critical materials of concern; (2) involve all stakeholders in the subject; (3) locate information on the critical material(s) in question; and (4) apply the information collected to improve the obsolescence risk determination.
