Which of the following is NOT a task in operation procurement?

In the context of operational procurement, the primary focus is on the processes involved in acquiring goods and services necessary for business operations. Tasks typically associated with operational procurement include managing purchase orders, facilitating requisitions through self-service portals, and utilizing analytics to assess procurement performance and identify trends.

Inventory costing, however, is primarily related to the management and valuation of inventory, focusing on how to account for the costs associated with the products held in stock. While inventory costing is a crucial aspect of supply chain management and financial accounting, it is not directly linked to the operational procurement activities which involve the actual buying process, supplier interaction, and procurement strategy implementation. This delineation is what makes inventory costing stand out as not being a task directly related to operational procurement activities.
