Final answer:
The Procurement Specialist is generally responsible for processing purchase requests for leased equipment, ensuring all acquisition procedures are properly followed.
Step-by-step explanation:
In the context of procurement and asset management within an organization, the Procurement Specialist typically processes purchase requests (PR) for leased equipment. While the Medical Equipment Custodian would manage the equipment after acquisition, the Finance Officer oversees budgetary concerns, and the Leasing Manager might negotiate and manage lease terms, it is the Procurement Specialist who is responsible for the acquisition process, including initiating PRs, evaluating suppliers, and ensuring that procurement policies are followed.
