The application of TRL metrics to existing cost prediction models

Technology Readiness Levels (TRLs) have been available for more than 25 years, first developed by the National Aeronautics and Space Administration (NASA) to ensure appropriate technology was reliable enough to be integrated into space systems. The Department of Defense (DoD) now requires their use in assessing both complex weapon system Critical Technology Elements (CTEs) and overarching program maturity. While use for technical readiness is well understood, their application to cost estimating still consists of a fragmented collection of factors and approaches.
