The RFP is a specification that states what type of Product and/or Service is being communicated to the prospective suppliers. Proposals must be delivered by the stated means and normally by e-mail on the specified day and time. The same is true for any questions about the RFP and the answers may then encourage the prospects to respond with acceptable Proposals or it may cause them to withdraw. This helps to identify who will be the suppliers and the timeline and cost of the deliverables requested. RFPs are used by all sizes of organisations that require Products or Services from outside suppliers. This is the normal way for businesses to transact and reach agreement on the delievrables. It also helps the parties to understand each others needs and wants and how they can then establish relationships with each other and build up their knowledgebase which helps them to fine tune future RFPs and Proposals. Therefore is form of communication is important for all businesses to work to gether and establish ongoing relationships.
