Technology Readiness Level (TRL)
Technology Readiness Level is a nine-point scale, originally from NASA and now widely used by defence and deep-tech funding bodies, that describes how mature a technology is - from TRL-1 (basic principles observed) through TRL-9 (proven in operational use). TRL-4 denotes a technology validated in a laboratory or controlled environment: the components work and the concept has been demonstrated, but it has not yet been proven in the field at operational scale. Stating a TRL honestly signals to technical reviewers exactly what has and has not been demonstrated.
