[Core] How is a buyer different from procurement, sourcing, or supply chain operations?

Example Answer

I separate them by scope and time horizon. A buyer is usually closer to day-to-day execution and supplier follow-through. Procurement is broader and can include sourcing, negotiation, contracts, policy, and internal governance. Strategic sourcing is usually even more market- and category-focused.

Supply chain operations is different again because it tends to focus on planning, inventory, logistics, and fulfillment rather than supplier selection and commercial terms. In smaller companies the lines blur, but that distinction still matters in interviews because I want to describe the work I have actually owned, not just use broad labels.

Common Poor Answer to Avoid

"They are basically all the same thing, just different company titles."

Why it's weak

It treats overlapping titles as proof of identical scope and does not distinguish actual decision ownership.

Why this works

It addresses role boundaries with a practical explanation and without inventing career results.
