A technology for an element intended for an application reaches the maturity level, corresponding to TRL 9, when it is well-defined by a set of reproducible processes for the design, manufacture, test and operation of the element and when, in addition, the element meets a set of performance requirements in the actual operational environment.
The element under consideration is assumed to be a physical part of a system. Systems are generally subdivided into sub-systems with potentially several sub-levels. The element can be any part of the system and is not necessarily a specific sub-system or at a specific sub-level.
A prerequisite for TRL assessment is the identification of the element that is subject to the assessment.
Higher TRLs further require the definition of the performance requirements, and therefore require the knowledge of the mission and the system where the element is intended to be used and its operational environment. Performance requirements can be preliminary and targeting several missions at low TRLs, then progressively refined and verified at higher levels.
The entire TRL scale applies for a given element. Therefore, there is no gradation in the element complexity when moving from low to high TRLS.
Higher TRLs also imply that the element is in its final form and is being integrated into a system for validation or use. Therefore, the TRL of a given element may be downgraded if this same element is used in a different system, unless all environment and interface requirements for the element in the new system can be demonstrated to be equally or less demanding than for the original system.
A TRL assessment is valid for a given element and at a given point in time. It may evolve if the conditions that prevailed at the time of the assessment are no longer valid. Such a situation may lead to TRL reassessment and degradation, which can occur in particular when the re-build/re-use of an element is envisioned. Examples are when the obsolescence of the electronics requires modifications or when the production involves a specific knowledge that has been lost.
The time or effort to move from one TRL to another are technology dependent and are not linearly connected to the TRL scale. Experience shows that they can vary widely depending on the element and mission under consideration. Therefore, while the TRL scale is an appropriate tool for assessing the technology maturity status at a given point in time, it gives no indication of the effort and cost to be spent for reaching the next level.ISO 16290 pdf download.
