Technology Readiness Levels

Understanding the level of a product’s maturity is key in determining the future steps towards commercialisation. Programmes will be designed to satisfy market requirements in terms of performance, quality, robustness and piece price. Agreeing the concept’s initial status allows appropriate plans to be developed.

The TRL scale is a metric for describing the maturity of a technology.

The acronym stands for Technology Readiness Level. The scale consists of up to 10 levels. Each level characterises the progress in the development of a technology, from the idea (level 1) to the full deployment of the product in multiple marketplaces and multiple applications (level 10).

The APC can help organisations working in a consortium when the technology has reached TRL 6 where a prototype has been verified, and this is defined in the Automotive Council document ‘Automotive Technology and Manufacturing Readiness Levels – A guide to recognised stages of development within the Automotive Industry‘, specifically:

  • A model or prototype of the technology system or subsystem has been demonstrated as part of a vehicle that can simulate and validate all system specifications within a test house, test track or similar operational environment.
  • Performance results validate the technology’s viability for a specific vehicle class.
