An Invitation to Tender (ITT) is typically used for complex, high-value procurements where the quality and specific features of the goods or services are of paramount importance. This approach ensures that ethical and responsible sourcing criteria are met, aligning with best practices in procuring specialised goods or services.

ISO 20400 is sustainable procurement.
14000 is environment
9001 is quality management
27001 is information security

Expenditure analysis by category/supplier enables buyers to track trends over time (A), supporting benchmarking and financial control. It also identifies opportunities for negotiation (C) by highlighting concentration of spend and potential leverage with suppliers. Marketing strategy, production scheduling, and stock disposal are outside procurement's primary scope. Responsible sourcing relies on robust spend analysis to identify efficiency opportunities, reduce wasteful expenditure, and support supplier relationship management strategies, all while aligning with sustainability and compliance goals.

total life-cycle costs include; acquisition costs, maintenance and training.
Added value and functional fit are quality criteria that should also be evaluated when selecting a supplier, but do not fall under total life-cycle costs.
Note: total life cycle costs and whole life asset management are the same thing. You may see both terms used in the exam. I think CIPS is moving more towards Whole Life Asset Management now as the preferred vocabulary but they're the same thing.

The EXW (Ex Works) term means the seller's responsibility ends once goods are made available at their premises. The buyer must take on costs and risks from that point, including loading, transport, and export clearance. Because the seller is not responsible for logistics, the quoted price is lower. In contrast, FCA includes delivery to a carrier, FOB covers loading onto a vessel, and CIP includes carriage and insurance arranged by the seller. By accepting these responsibilities, the buyer leveraged cost savings, demonstrating knowledge of Incoterms and alignment with efficient sourcing practices.
