Technology Readiness Level

What Is Technology Readiness Level?

Technology readiness levels (TRLs) are used to assess the maturity of a particular technology. TRL is a nine-point scale system from TRL 1, which denotes the fundamental idea, to TRL 9, which denotes proven field operation. An overview of the TRL scale is shown in the figure below. A TRL number is assigned once the technology accomplishes the specifications of that TRL.

Engineers and scientists use TRL because:

  • It measures the maturity of a technology at a given point of time in the technology development cycle.
  • It provides guidance in further developing the maturity of a technology.
  • It provides a framework for technology transfer with industry-academia collaboration.

Model-Based Design using MATLAB®, Simulink®, and Stateflow® supports technology development stages from early-stage feasibility through in-service operation as defined by TRLs.

Using Model-Based Design in the technology development process offers the following benefits:
