Manufacturing 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 MRL scale is a metric for describing the maturity of a technology.

The acronym stands for Manufacturing 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 MRL 4 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:

  • Capability exists to produce the technology in a laboratory or prototype environment.
  • Series production requirements, such as in manufacturing technology development, have been identified.
  • Processes to ensure manufacturability, producibility and quality are in place and are sufficient to produce demonstrators.
  • Manufacturing risks have been identified for prototype build.
  • Cost drivers have been confirmed.
  • Design concepts have been optimised for production.
  • APQP processes have been scoped and are initiated.
