Generally, SC Major System Projects do not require a Technology Readiness Assessment (TRA), and technical readiness is asssessed by technical sub-committees in reviewing Design Reports and in an IPR.  Where a significant critical technology element modification occurs subsequent to CD-2, however, a Technology Readiness Assessment may be appropriate.  

The TRA model evaluates technology maturity using the Technology Readiness Level (TRL) scale. TRAs and associated Technology Maturation Plans are used as a project management tool to reduce the technical and cost risks associated with the introduction of new technologies. Where technological readiness is a significant concern, TRAs should be considered for alternatives under consideration.

Major System Projects, or first-of-a-kind engineering endeavors, must be assessed prior to each CD using the Technology Readiness Assessment and should achieve the following minimum TRL scores for each critical technology item or system as determined by an independent review team outside of the project team before that CD can be approved. The higher the TRL at CD-2, the lower the risk to the project. The following represents the minimum TRL at each CD:

• CD-1: TRL 4

• CD-2: TRL 7

For Major System Projects where new critical technologies are being deployed, the TRA shall be conducted and the associated Technology Maturation Plan developed prior to CD-2. On those projects where a significant critical technology element modification occurs subsequent to CD-2, conduct another TRA prior to CD-3. It is strongly encouraged for use by projects with a TPC less than $750M.
