What is Technology Readiness Level?
Technology Readiness Level (TRL) is a scale developed by NASA to measure the maturity of a technology. It helps organizations understand how ready a technology is for real-world use, from initial concept to full deployment.
The scale ranges from TRL 1 (basic principles) to TRL 9 (proven system in operational environment).

TRL Phases
Technology Readiness Levels are grouped into three main phases of development:
Research Phase (TRL 1-3)
Focus: Basic research and proof of concept
- TRL 1: Basic principles observed
- TRL 2: Technology concept formulated
- TRL 3: Proof of concept demonstrated
Development Phase (TRL 4-6)
Focus: Component validation and system integration
- TRL 4: Component validation in laboratory
- TRL 5: Component validation in relevant environment
- TRL 6: System/subsystem model demonstrated
Deployment Phase (TRL 7-9)
Focus: System testing and operational deployment
- TRL 7: System prototype in operational environment
- TRL 8: System complete and qualified
- TRL 9: System proven in operational environment
