Which of the following are types of responsibility member functions in responsibility management?

The designation of operational purchaser as a type of responsibility member function in responsibility management is accurate because operational purchasers are primarily involved in the day-to-day procurement activities. They handle tasks such as order processing, supplier communication, and ensuring materials are available for production needs. This role is crucial in maintaining the flow of necessary goods and services, making it a specific responsibility within the procurement function.

In contrast, while the other choices represent various roles or categorizations within procurement, they do not specifically align with the concept of a responsibility member function. Purchasing group 002 and material group L002 refer to organizational structures or classifications within the purchasing process, rather than individual roles focused on specific operational tasks. Strategic purchasing usually relates to long-term planning and supplier relationship management, which is distinct from the operational focus of an operational purchaser. Hence, these roles, while important in their own right, do not represent a type of responsibility member function within the context of responsibility management.
