Unfortunately, the evaluator reads your proposal next, and you didn't include a risk analysis. In spite of the evaluation criteria, evaluators now recognize that proposal number three is superior and that the company understands the project. That vendor has succeeded in altering the evaluation process and having its proposal adopted as the standard. Evaluators don't like promises without a description of how you plan to keep them. Ensure that your proposals are specific, the plan is detailed and the deliverables are described.
Evaluators are suspicious by nature.
They have probably been mislead by vendors in the past, and they are aware of the lengths some vendors will go to make a sale. If an RFP states a requirement, evaluators know the vendor will say the solution is available. Names and addresses are provided in the reference section. Easy to follow, well-written proposals receive higher scores. Ensure that your proposal is easily understood by a typical evaluator.
