At ITF, we use the NASA Technology Readiness Level (TRL) scale
Technology Readiness Levels (TRL) are a type of measurement system used to assess the maturity level of a particular technology. Each technology project is evaluated against the parameters for each technology level and is then assigned a TRL rating based on the projects progress. There are nine technology readiness levels. TRL 1 is the lowest and TRL 9 is the highest.
An overview of each level can be found below:
TRL One - The Idea
Basic principles have been observed. Research begins into possible applications
TRL Two - Invention begins
Technology concept is formulated. Speculative, practical applications suggested
TRL Three - Active R&D is initiated
Analytical studies and experiments validate critical functions and/or components
TRL Four - Components validated in laboratory
Basic technological components are integrated to establish that they work together
TRL Five - Components validated in relevant environment
Basic technological components are integrated and tested in a simulated environment
TRL Six - Advanced prototype tested in relevant environment
More advanced system model or prototype demonstrated in a simulated environment
TRL Seven - Advanced prototype tested in operational environment
Advanced field testing of the actual system prototype in operational environment
TRL Eight - Completed technology proven through test and demonstration
Technology completed and qualified in its final form and under expected conditions
TRL Nine - Completed technology proven through successful commercial operations
Actual application of the technology in its final form and under normal conditions.
If you have any questions regarding the TRL scale please contact the Technology Team in the Aberdeen office.
