Which category of spend item would be most suitable to purchase through an e-auction?

Leverage items, as defined by the Kraljic purchasing portfolio matrix, are characterised by high profit impact and low supply risk. This means they represent a significant portion of expenditure but are available from a competitive market with multiple qualified suppliers. E-auctions are most effective in such scenarios. They create a highly competitive, price-transparent environment where suppliers bid against each other, allowing the buying organisation to leverage its purchasing power to achieve the best possible price. The clear specifications and ample supply base for leverage items make them ideal for the price-focused, competitive nature of an e-auction.

A. Bottleneck: These items have high supply risk and few suppliers. Using an e-auction would be counterproductive, potentially alienating the limited supply base and jeopardising supply continuity.
C. Strategic: These items are critical and involve long-term, collaborative supplier relationships. An e-auction's focus on price can damage the trust and partnership essential for managing strategic items.
D. Non-critical: While an e-auction is possible, the low profit impact of these items means the potential cost savings may not justify the administrative effort and resources required to run the event.

In the section on portfolio analysis, it outlines that the appropriate strategy for leverage items is to exploit purchasing power through competitive bidding, for which e-auctions are a primary tool (typically discussed in Chapter 2).

2. van Weele, A. J. (2018). Purchasing and Supply Chain Management (7th ed.). Cengage. Chapter 5, "Purchasing Portfolio Analysis," details the Kraljic matrix. It explicitly links the 'Leverage Quadrant' to sourcing strategies such as "competitive bidding" and "e-auctions" to exploit the buyer's power in a market with many suppliers (pp. 168-170).

Leverage items are defined as those where the "balance of power" favours the buyer, making competitive pressure tactics, like auctions, a logical approach.
