BEST VALUE EVALUATION CRITERIA: 1.0 This requirement will be evaluated on a Best Value basis. 2.0 Minimum Requirements Methodology -- Each offeror will be evaluated to determine if their proposal meets the minimum requirements stated in the description/Section C above. This is a Pass/Fail criteria. 3.0 Added Value Methodology -- There are three elements which have added value to the Government. Each of the added value elements is essentially equal in importance. Image Rejection -- (Description Element C.3.f) Exceeds the 60 dBm minimum requirement. IF Rejection -- (Description Element C.3.g) Exceeds the 60 dBm minimum requirement. Warranty -- (Description Element C.10) Exceeds the 1 year minimum. 4.0 Past Performance Each offeror shall provide the name and points of contact of the last five sales to whom they have provided the same or similar equipment. Past performance is essentially two and one-half times as important as the added value elements. Each reference/point of contact will be asked to rate the quality of the product, timeliness of delivery, product support, and cost control. 5.0 Price is not scored in this evaluation and is not considered the most important evaluation factor. The importance of price as an evaluation factor will increase with the degree of equality of the proposals in relation to the remaining evaluation factors. After evaluation of the technical and price proposals, cost may be the deciding factor for selection, depending on whether a highly evaluated technical proposal warrants the evaluated price difference. 6.0 Specific Evaluation Criteria Minimum Requirements -- See Description/Section C above Added Value Items -- There are three added value elements of the description in which exceeding the minimum requirements is an added value to the Government.
