Use of TRL in the systems engineering toolbox

Abstract. Technology Readiness Level (TRL) is used to evaluate the maturity of the Critical Technology Elements (CTE) in a project or program and indicates an assumed level of the remaining technical risks for each independent technology. This paper presents results of a literature review exploring the diversity of definitions applied to TRL. Survey results explore whether and how TRLs are used. Based on these results the authors assess to what degree TRL evaluations are suitable for organizations without separately trained and skilled readiness assessment personnel.
