Technology Readiness Levels and Space Program Schedule Change

摘要

IN A paper written by Dubos et al. [1], the authors make several assertions associated with: 1) technology readiness level (TRL) and schedule risk, 2) probability distributions associated with schedule change, and 3) modeling schedule change and risk. Some of these assertions will be briefly examined in this paper along with results obtained from evaluating a sample of 28 NASA programs used by Dubos et al. [1].
