Technology Readiness Levels (TRLs) have been used extensively from the 1970s, especially in the National Aeronautics and Space Administration (NASA). Their application was recommended by the General Accounting Office in 1999 to be used for major Department of Defense acquisition projects. Manufacturing Readiness Levels (MRLs) have been proposed for improving the way manufacturing risks and readiness are identified; they were introduced to the defense community in 2005, but have not been used as broadly as TRLs. Originally TRLs were used to assess the readiness of a single technology. With the emergence of more complex systems and system of systems, it has been increasingly recognized that TRLs have limitations, especially when considering integration of complex systems. Therefore, it is important to use TRLs in the correct context. Details on TRLs and MRLs are reported in this paper. More recent indices to establish a better understanding of the integrated readiness state of systems are presented. Newer readiness indices, System Readiness Levels (SRLs) and Integration Readiness Levels, are discussed and their limitations and advantages are presented, along with an example of computing SRLs. It is proposed that a modified SRL be considered that explicitly includes the MRLs and a modification of the TRLs to include the Integrated Technology Index (ITI) and/or the Advancement Degree of Difficulty index proposed by NASA. Finally, the use of indices to perform technology assessments are placed into the overall context of technology management, recognizing that factors to transition and manage technology include cost, schedule, manufacturability, integration readiness, and technology maturity.
