Abstract
Early in the lifecycle of a system development, systems engineers must execute
trade studies to allocate resources between different research and development efforts that are
developing technologies to be deployed into the system, and they must prepare risk
management plans for the selected technologies. We have been developing a statistical model
for schedule and cost uncertainty based on a small number of inputs that are quite objective
and are already integrated with technology readiness assessment. An algorithm that
transforms Technical Maturity (TM) scores from Department of Energy projects into a
Technology Readiness Level (TRL) score was created, allowing us to add data from a US
Department of Energy to an existing set of data from NASA. We statistically tested whether
the two samples (i.e. the DoE and NASA datasets) were randomly drawn from the same
population and concluded that the transition times for developing aerospace and nuclear
technologies are very similar.
