As someone who has spent some hours around Contracting Officers I can attest to this. Based on the conversation I had with a "CO" he was informing me that they're getting away from "LPTA" because its attracting the wrong kind of contractors which usually means that the contractor will fall short of the "SOW" and either they can fulfill the Contract or it results in a change order outside of the agreed price. He explicitly stated the key things they look for is "ability to understand the contract" "people can have the lowest price, but if their proposal isn't any good we skip right over it." So my take away is, focus more on creating a professional concrete proposal and all of your business marketing, websites etc to back up who you say you are.
