Issues Inv0lvii1g Uhcebiainiies in Defense Acquisitiok and a Method for Dealing with Them

This paper analyzes two work processes involved in defense acquisition which are replete with uncertainties. These are the proposal phase and the architectural design phase. Both phases involve a vendor designing alternative system in response to a set of stated (and perceived.) requirements, followed by the government agency's final selection of a preferred system design (and a preferred contractor). Since these efforts many times occur during the preliminary phases of the acquisition process, many uncertainties are present, including: technological uncertainties, uncertainties in the timely availability . " inputs, workload uncertainties, and equipment reliability and maintainability, all of which lead to performance, schedule, and cost uncertainties.
