6.2  Lowest Price Technically Acceptable (LPTA).

The LPTA process is appropriate when best value is expected to result from selection of the technically acceptable proposal with the lowest evaluated price.  

Past performance does not have to be an evaluation factor in LPTA, as with other types of source selection processes, if the contracting officer documents the file pursuant to FAR 15.304(c)(3)(iv).  The contracting officer, requirements personnel and legal, if applicable, should thoroughly discuss the evaluation of past performance in a LPTA source selection.  Since award made to the lowest price technically acceptable offeror, past performance normally becomes a part of the contracting officer's responsibility determination under FAR 9.1.
