7. Selection Procedure No TBD’s in document
October 2009
Selection Procedure
No TBD’s in document
In 09/935r3, presentation of new techniques occur prior to presentation of complete proposals
Main issue raised in September was allowing time after presentation of complete proposals to present new techniques
