What primary factor increases competition when responding to a draft RFP?

Providing timely information is crucial in increasing competition when responding to a draft RFP because it ensures that all potential bidders have equal access to the information they need to prepare their proposals. When information is disseminated promptly, it allows enough time for respondents to thoroughly understand the requirements and address any questions or concerns they may have.

Timely information can lead to a more informed pool of bidders, as they can make necessary adjustments to their proposals based on the latest updates and insights. This facilitates better alignment with the RFP's objectives and enhances the quality of the proposals received. In turn, a well-informed and prepared bidder base typically results in a more competitive environment.

The other options, while relevant in the context of RFPs, do not directly facilitate increased participation and competitiveness in the same way that timely information does. For instance, the number of amendments might create confusion or uncertainty, the complexity of the RFP could deter potential respondents from participating, and the cost of proposals can influence the willingness of bidders to compete but doesn't inherently enhance competition itself.
