Technology readiness levels (TRL) are a method of estimating technology maturity of Critical Technology Elements (CTE) of a program during the acquisition process. They are determined during a Technology Readiness Assessment (TRA) that examines program concepts, technology requirements, and demonstrated technology capabilities. TRL are based on a scale from 1 to 9 with 9 being the most mature technology. The use of TRLs enables consistent, uniform discussions of technical maturity across different types of technology. A comprehensive approach and discussion about TRLs has been published by the European Association of Research and Technology Organisations (EARTO). Extensive criticism of the adoption of TRL scale by the European Union was published in The Innovation Journal, in that "concreteness and sophistication of the TRL scale gradually diminished as its usage spread outside its original context (space programs)".

Definitions
Different definitions are used. Although they are conceptually similar, significant differences exist in terms of maturity at a given technology readiness level.
U.S. Department of Defense (DoD) definitions
Related DoD definitions
The DoD uses similar definitions for the following specialized areas:
- Software Technology Readiness Levels
- Biomedical Technology Readiness Levels
- Manufacturing Readiness Level
NASA definitions
ESA definition
Instruments and spacecraft sub-systems technical maturity with respect to a specific space application are classified according to a "Technology Readiness Level" (TRL) on a scale of 1 to 9. ESA is utilising the ISO standard 16290 Space systems - Definition of the Technology Readiness Levels (TRLs) and their criteria assessment.
European Commission definition
Oil and gas industry (API 17N)
The following definition is based on API recommended practice and is used in the oil and gas industry.
Other definitions and uses
The Build in Canada Innovation Program administered by Public Services and Procurement Canada provides assistance by awarding contracts to entrepreneurs with pre-commercial innovations, provided the innovation has a TRL between 7 and 9.
The Federal Aviation Administration (FAA) references technology readiness levels in some of their documents, and seems to rely on the NASA definitions.
The United States Department of Energy (DOE) uses the following guidelines throughout the department in conducting Technology Readiness Assessments (TRAs) and developing Technology Maturation Plans (TMPs).

Brief history
Technology Readiness Levels were originally conceived at NASA in 1974 and formally defined in 1989. The original definition included seven levels, but in the 1990s NASA adopted the current nine-level scale that subsequently gained widespread acceptance.
Original NASA TRL Definitions (1989)
- Level 1 - Basic Principles Observed and Reported
- Level 2 - Potential Application Validated
- Level 3 - Proof-of-Concept Demonstrated, Analytically and/or Experimentally
- Level 4 - Component and/or Breadboard Laboratory Validated
- Level 5 - Component and/or Breadboard Validated in Simulated or Realspace Environment
- Level 6 - System Adequacy Validated in Simulated Environment
- Level 7 - System Adequacy Validated in Space
The TRL methodology was originated by Stan Sadin at NASA Headquarters in 1974. At that time, Ray Chase was the JPL Propulsion Division representative on the Jupiter Orbiter design team. At the suggestion of Stan Sadin, Mr Chase used this methodology to assess the technology readiness of the proposed JPL Jupiter Orbiter spacecraft design. Later Mr Chase spent a year at NASA Headquarters helping Mr Sadin institutionalize the TRL methodology. Mr Chase joined ANSER in 1978, where he used the TRL methodology to evaluate the technology readiness of proposed Air Force development programs. He published several articles during the 1980s and 90s on reusable launch vehicles utilizing the TRL methodology. These documented an expanded version of the methodology that included design tools, test facilities, and manufacturing readiness on the Air Force Have Not program. The Have Not program manager, Greg Jenkins, and Ray Chase published the expanded version of the TRL methodology, which included design and manufacturing. Leon McKinney and Mr Chase used the expanded version to assess the technology readiness of the ANSER team's Highly Reusable Space Transportation ("HRST") concept. ANSER also created an adapted version of the TRL methodology for proposed Homeland Security Agency programs.
The United States Air Force adopted the use of Technology Readiness Levels in the 1990s.
In 1995, John C. Mankins, NASA, wrote a paper that discussed NASA's use of TRLs and proposed expanded descriptions for each TRL. In 1999, the United States General Accounting Office produced an influential report that examined the differences in technology transition between the DOD and private industry. It concluded that the DOD takes greater risks and attempts to transition emerging technologies at lesser degrees of maturity than does private industry. The GAO concluded that use of immature technology increased overall program risk. The GAO recommended that the DOD make wider use of Technology Readiness Levels as a means of assessing technology maturity prior to transition. In 2001, the Deputy Under Secretary of Defense for Science and Technology issued a memorandum that endorsed use of TRLs in new major programs. Guidance for assessing technology maturity was incorporated into the Defense Acquisition Guidebook. Subsequently, the DOD developed detailed guidance for using TRLs in the 2003 DOD Technology Readiness Assessment Deskbook.
TRL in the European Union
The European Space Agency adopted the TRL scale in the mid-2000s. Its handbook closely follows the NASA definition of TRLs. The universal usage of TRL in EU policy was proposed in the final report of the first High Level Expert Group on Key Enabling Technologies, and it was indeed implemented in the subsequent EU framework program, called H2020, running from 2013 to 2020. This means not only space and weapons programs, but everything from nanotechnology to informatics and communication technology.
Assessment tools
A Technology Readiness Level Calculator was developed by the United States Air Force. This tool is a standard set of questions implemented in Microsoft Excel that produces a graphical display of the TRLs achieved. This tool is intended to provide a snapshot of technology maturity at a given point in time.
The Technology Program Management Model was developed by the United States Army. The TPMM is a TRL-gated high-fidelity activity model that provides a flexible management tool to assist Technology Managers in planning, managing, and assessing their technologies for successful technology transition. The model provides a core set of activities including systems engineering and program management tasks that are tailored to the technology development and management goals. This approach is comprehensive, yet it consolidates the complex activities that are relevant to the development and transition of a specific technology program into one integrated model.
Uses
The primary purpose of using technology readiness levels is to help management in making decisions concerning the development and transitioning of technology. It should be viewed as one of several tools that are needed to manage the progress of research and development activity within an organization.
Among the advantages of TRLs:
- Provides a common understanding of technology status
- Risk management
- Used to make decisions concerning technology funding
- Used to make decisions concerning transition of technology
Some of the characteristics of TRLs that limit their utility:
- Readiness does not necessarily fit with appropriateness or technology maturity
- A mature product may possess a greater or lesser degree of readiness for use in a particular system context than one of lower maturity
- Numerous factors must be considered, including the relevance of the products' operational environment to the system at hand, as well as the product-system architectural mismatch
Current TRL models tend to disregard negative and obsolescence factors. There have been suggestions made for incorporating such factors into assessments.
