In the Plan-Source-Make-Deliver framework, which function is responsible for acquiring materials?

• A. Source
• B. Plan
• C. Deliver
• D. Make

Answer: (A)

The function responsible for acquiring materials is the Source function. In Plan-Source-Make-Deliver, Source covers procurement activities: identifying and selecting suppliers, negotiating contracts, purchasing materials, and bringing inbound materials into the operation. It focuses on obtaining the right materials at the right time and cost, so production can proceed as planned.

Plan handles forecasting, demand and capacity planning, and aligning resources; Make is the production process that converts inputs into finished goods; Deliver handles warehousing, transportation, and getting products to customers. So sourcing specifically deals with obtaining materials, making it the best fit for acquiring inputs.
