Technology Readiness Levels explained!

This is a quick-reference app for the Department of Defense and NASA Technology Readiness Levels (TRLs).

It features definitions for both DoD and NASA!

For each TRL, the app includes:

*Supporting information (DoD only)
*SETR Process alignment (DoD only)

Everyone needs a reminder now and then. What's the difference between 5 and 6? Is your invention really a 4 or a 5? What's the difference between 1 and 2?

All ThinChip Software apps are now available free of charge.
