TRL is determined during a technology readiness assessment (TRA) that examines program concepts, technology requirements, and demonstrated technology capabilities. TRLs are based on a scale from 1 to 9 with 9 being the most mature technology.

A TRA involves a fundamental metric, the Technology Readiness Level (TRL), first developed at the National Aeronautics and Space Administration (NASA) in the 1970s. In 1999, the Government Accountability Office (GAO) (then General Accounting Office) published an influential report, Best Practices: Better Management of Technology Can

2024年5月2日 · Definition: Technology Readiness Levels (TRL) are a method used to measure and assess the maturity of a particular technology. They allow engineers, managers and project personnel a consistent point of reference for figuring out how a technology is changing. TRL is based on a scale from 1 to 9, with 9 being the most mature technology.

2023年9月27日 · There are nine technology readiness levels. TRL 1 is the lowest and TRL 9 is the highest. When a technology is at TRL 1, scientific research is beginning and those results are being translated into future research and development.

Check out the TRL assessment tool to help you narrow it down. These are the 9 technology readiness levels, with 1 being the least ready and 9 being already used in real-life conditions.

Technology Readiness Levels (TRL) are different points on a scale used to measure the progress or maturity level of a technology. The scale ranges from 1 to 9, where TRL 1 is the lowest and TRL 9 is the highest.

A TRA evaluates technology maturity using the Technology Readiness Level (TRL) scale that was pioneered by the National Aeronautics and Space Administration (NASA) in the 1980s. TRL indicates the maturity of a given technology, as defined in Table 1. Figure 1 provides a schematic of the meaning of the TRLs in the context of DOE EM projects.

2024年8月8日 · The TRL scale assesses the maturity level of a technology from its initial concept to its full integration into an operational system and commercial deployment. It comprises nine levels, each defining a specific stage of technological development.

2010年8月20日 · At NASA, as in the rest of the research community, these grades are called technology readiness levels, or TRLs. Each TRL represents the evolution of an idea from a thought, perhaps written on a cocktail napkin or the back of an envelope, to the full deployment of a product in the marketplace.

Technology Readiness Level (TRL) scale was first employed by NASA in 1974 to evaluate the maturity of technologies for spacecraft design as part of risk assessment. It was demonstrated that transition of emerging technologies at lesser degrees of maturity results in higher overall risk.
