Which document authorizes the purchasing department to buy specified materials in specified quantities within a specified time?

• A. Purchase order
• B. Purchase requisition
• C. Quality costs
• D. Quick changeover

Answer: (B)

In procurement, the document that internally authorizes buying is the purchase requisition. It comes from a department needs to the purchasing function and specifies what materials are needed, in what quantity, and by when. Once this internal request is approved, the purchasing department can issue a purchase order to a supplier to actually place the purchase. The purchase order is the outward contract with the supplier, not the internal authorization. The other options don’t fit the authorization role: a work-order or quality cost topic aren’t about authorizing purchases, and quick changeover relates to manufacturing setup, not procurement authorization.
