Old school: Negotiate the lowest price and break the supplier's arm. New school (fundamental): Total Cost of Ownership (TCO).

The Supply Chain Operations Reference (SCOR) model provides a standard framework for understanding SCM fundamentals:

| Component | Description | Key Activities | |-----------|-------------|----------------| | 1. Plan | The strategic phase. Balancing demand and supply to develop a course of action. | Demand forecasting, supply planning, production scheduling, inventory planning, S&OP (Sales & Operations Planning). | | 2. Source | Procuring raw materials and services needed to create products. | Supplier selection, contract negotiation, purchase order management, supplier evaluation, inbound logistics. | | 3. Make | The manufacturing or transformation process. | Production execution, quality control, packaging, work-in-progress tracking, equipment maintenance. | | 4. Deliver | Managing orders, transportation, and distribution to customers. | Order management, warehouse operations, transportation management (inbound/outbound), delivery scheduling, invoicing. | | 5. Return | Reverse logistics: handling defective, excess, or unwanted products. | Returns authorization, inspection, repair/recycling, disposal, warranty management. |

Every morning, each bakery’s supply chain looked like a simple river:

Le Pain Moderne, run by a talented baker named Elise, believed only the bread mattered. "I am an artist," she said, "not a logistics clerk." She bought flour from whoever had the lowest price that week. She baked as much as she felt like baking. If she ran out of bread by 3 PM, well, that was a good day. If she had too much, she threw it away.

The Golden Oven, run by a quiet man named Amir, saw things differently. "Baking is art," he agreed. "But keeping the art flowing is science." Amir took a course on the Fundamentals of Supply Chain Management.
