Based on hardness assurance (HA) cost trade studies conducted on a low-cost/high-volume tactical military system with moderate radiation environments, conventional strategies for design hardening and HA can result in higher life-cycle costs (LCC) than alternate approaches. The trade studies used variables designed to investigate LCC as a function of several critical parameters, including semiconductor procurement option, system quantity, HA testing option, and other variables. An LCC model and sample problem are included to illustrate the key results. Following the results of the trade studies, limitations of the simplified cost model are presented, the relationship of these results to current procurement practices are discussed, and the application of the results to modern military and commercial systems is discussed
