3-5: Concepts proven, software solution to be proven. Any external release for a period of less than 2 years. Any subsequent release would be Production. |
|
Beta |
6-7: Proven software solution with ongoing development, collecting user feedback or satisfying Preproduction requirement. External release follows lifecycle plan. Any subsequent release would be on Production. |
|
Production |
8-9: Proven software solution being developed. External release follows lifecycle plan. |
Refer to the Technology Readiness Levels (TRLs) table for complete list of TRLs as used at EPRI.
Note: EPRI developed software which has not previously been released to EPRI Members is required to be initially submitted to SQA as "Preproduction" (Prototype, Proof-of-Concept, Beta) unless an exemption is provided. If your software has previously been released, the "Preproduction" submittal is optional for all future releases.
