Selecting and Weighting Evaluation Factors and Subfactors

You must clearly state in the solicitation and source selection plan all the evaluation factors and subfactors that you will consider in making the source selection and their relative importance or weight. These factors and subfactors inform offerors of all the significant considerations in selecting the best value source and the relative importance the Government attaches to each of these considerations. Offerors should understand the basis upon which their proposals will be evaluated and how they can best prepare their proposals. The evaluation factors will be cost, past performance, and non-cost, by nature.

Structure evaluation factors and subfactors and their relative order of importance to clearly reflect the Government's need and facilitate preparation of proposals that best satisfy that need.

A multi-disciplined team chooses the evaluation factors and subfactors based on user requirements, acquisition objectives, perceived risks, and thorough market research. Thorough research of the market helps the team identify the capabilities of different industry sectors and where those capabilities are most likely to differ among potential offerors. The team then selects only those factors that will help differentiate among offerors and surface the most advantageous offer.

Evaluation factors and subfactors must be limited to those areas which will reveal substantive differences or risk levels among competing offers.

Best Practices

Selecting the right evaluation factors is one of the most important decisions you will make in designing your evaluation process. We are often faced with the triple problems of less time, less funds, and fewer available personnel to devote to source selections. If you do not concentrate on what is important in selecting the best value offeror you could end up with a large evaluation team wasting a lot of time and effort looking at issues that do not differentiate between offerors and a weak evaluation that does not give the source selection authority the information needed to make a good selection.

There are certain factors that you must consider in any competitive source selection. Price/cost is an automatic factor that you always have to consider. You also have to consider past performance in your evaluation process unless the contracting officer documents why it is not appropriate for the specific circumstances of the acquisition . From here you add other factors and subfactors that are important to deciding which is the most advantageous offer. Remember, not everything that the offeror has to do under the contract is really a discriminator that will help you decide which offer will result in the best value. Consider what you are buying and what will really discriminate between offers.

How to select the additional factors/subfactors? Consider the following methodology:

  1. Research the market for what you are buying and your probable universe of offerors.
  2. Form a team and brainstorm critical factors and subfactors.
  3. Select only those factors and subfactors likely to surface the most advantageous offers.
  4. Define the key discriminators and prioritize the list.
  5. Get source selection authority approval of the list of factors/subfactors.
  6. Clearly and concisely tell offerors in the solicitation what the factors/subfactors are and their relative importance.
  7. Listen carefully to industry feedback from presolicitation exchanges to see if your choices are right. If necessary, change the factors/subfactors before solicitation.

Weighting the Factors and Subfactors

After determining the evaluation factors and subfactors, their relative importance to each other must be established. The relative importance of factors and subfactors must be consistent with the stated solicitation requirements. If their relative importance does not accurately reflect the Government's requirements and objectives, the source selection authority may later award to an offeror whose proposal may not be most advantageous to the Government. As a general rule, the higher the technical or performance risk, the greater the emphasis on non-cost factors. The relative importance between all non-cost factors combined and cost or price must also be described using the terms significantly more important, approximately equal, or significantly less important. This relative ranking must be reflected in both the solicitation and the weights or priority statements in the source selection plan.

The relative importance of evaluation factors and subfactors is usually established by priority or tradeoff statements, numerical weighting, or a combination of these.

Although numerical weights may be used in making the tradeoff analysis and decision the weights themselves may, but need not be disclosed in the solicitation. If you do not disclose the numerical weights themselves in the solicitation, they must be described in terms of priority or tradeoff statements.

Cost/price as an evaluation factor is never scored or rated as part of the evaluation. But, just like all the other factors and subfactors, cost/price has to be weighted to indicate its importance relative to the other evaluation factors and subfactors and the overall evaluation. The weight given to cost/price reflects its relative importance in selecting the best proposal for award. The circumstances of your particular acquisition will indicate how important cost/price is in satisfying your requirement.
