Have you seen "Best Value with LPTA" used before? If so, can you explain the rationale for what appears to be contradictory evaluation criteria? When I was trained, it was Best Value or LPTA, indicating the priority of the evaluation. If the priority was brand-name, delivery schedule, or quality you would use best value. LPTA was the simplest expression of "we need this particular widget, cheapest offer wins".
I'm still not sure how combining those two really makes sense. Perhaps our resident philosopher may have some insight....
