A procurement professional is negotiating with a supplier on cleaning service. She realises that there are huge cost-saving opportunities if the supplier agrees to reduce its mark-up and unnecessary employee benefits. Supplier's mark-up and employee benefits are examples of which of the following?

Addressable spend is the portion of an organisation's total expenditure that can be realistically influenced or managed by procurement actions to achieve cost savings or value improvements. In this scenario, the supplier's mark-up and employee benefits are components of the total cost that the procurement professional can directly negotiate to reduce. By targeting these specific cost elements, she is working within the addressable spend to generate savings. The other options refer to tools or methods for analysing spend, not a category of spend itself.

A. A spend waterfall is a chart that visualises how savings are achieved against a baseline spend; it is a reporting tool, not a type of spend.
B. A spend cube is a data analysis model that segments spend by category, supplier, and business unit to identify opportunities, not a category of spend.
C. A spend tree is a hierarchical classification system used to categorise spend data for analysis, not a type of spend that can be influenced.
