1. Chartered Institute of Procurement & Supply (CIPS). (2019). Commercial Contracting (L4M3) Study Guide. Profex Publishing. In the section covering sourcing processes (typically Chapter 2)
the guide explains that an RFQ is used for straightforward
low-value requirements where the specification is clear. It emphasizes that because the requirement is well-defined
the award decision is usually based on the lowest price from a supplier capable of meeting the terms.

'Sourcing'
the text distinguishes between different sourcing documents
stating
"A request for quotation (RFQ) is an invitation to suppliers to bid on specific products or services... The RFQ is primarily a price-focused document" (p. 315). It also supports the use of approved supplier lists for efficiency and risk reduction.

'Supplier Evaluation and Selection'
clarifies that an RFQ is used when "the buyer is seeking bids for a simple requirement where the specifications are known and not open to variation... the award is typically made to the lowest-priced bidder" (p. 268).
