Sorry, jargon: https://en.m.wikipedia.org/wiki/Technology_readiness_level https://en.m.wikipedia.org/wiki/Technology_readiness_level Funny thing, the wiki page explicitly cites horizon2020 (which one of the GPs criticized): "The European Commission advised EU-funded research and innovation projects to adopt the scale in 2010.[1] TRLs were consequently used in 2014 in the EU Horizon 2020 program. In 2013, the TRL scale was further canonized by the ISO 16290:2013 standard.[1] A comprehensive approach and discussion of TRLs has been published by the European Association of Research and Technology Organisations (EARTO).[3] Extensive criticism of the adoption of TRL scale by the European Union was published in The Innovation Journal, stating that the "concreteness and sophistication of the TRL scale gradually diminished as its usage spread outside its original context (space programs)"."
