Commercial Readiness Level 

CRL – Commercial Readiness Level is a measure on a scale of 1 to 9 of how ready a technology is to be made commercially available, starting from the belief a new technology could be commercially successful all the way through to full regulatory compliance, commercial availability and wider acceptance within the target market. The definition of each level is defined in the table below.


 CRL Definition
1Basic hypothesis that a new technology would be commercially viable.
2Basic market awareness demonstrated.
3Applications of technology found.
4Identify support needed from supply chain, plus any certification and regulatory requirements.
5Financial model for sales, costs and margins established.
6Confirm exploitation routes; form partnerships across the value chain; and certification and regulatory  requirements underway.
7Financial model/commercial viability validated.
8First commercial system built; route to market established; market assumptions updated.
9Technology has been introduced to market.

The product or technology evaluated could be hardware, software or a system combining both:
  • Hardware: for example a robotic probe manipulator to provide automated inspection data collection.
  • Software: for example a suite of image processing techniques to aid inspection data interpretation.
  • System: for example a collaborative robot (hardware) that uses sophisticated path planning tools (software) to inspect complex materials.

The Research Centre in Nondestructive Evaluation (RCNDE) uses this CRL scale alongside the Technology Readiness Level (TRL) scale (see May’s What the Hec?!) to assist with the efficient development of NDT research projects, where CRL assessment is used to ensure that technologies are fit for end-users and eventual use.
