The correct answer is 'No- a reverse e-auction would be more suitable as it will secure the lowest price'. An E-auction is something like eBay- where bids go up in price. If David wants to secure a lower price, he should use a Reverse E-Auction- where suppliers bid lower than the previous bid in order to win. For example, Supplier 1 offers to fulfil the contract at £50k per year, Supplier 2 can offer to beat this price by bidding £48k per year. Although Reverse E-Auctions may ensure cheaper prices, there are a lot of disadvantages to using this method. See p.21 and p.76 for more information

Effective cost modelling is a process that helps in understanding the cost structure of a product or service. It involves:
* Data gathering:Collecting relevant data related to materials, labor, overheads, and other cost drivers.
* Analysis of facts:Evaluating the collected data to understand cost behaviors and identify areas for cost reduction.
Supplier negotiation and issuing a request for quotation are subsequent steps that may utilize the insights gained from cost modelling but are not part of the modelling process itself.
