What decision this helps you make: Whether to single-source for a lower price, and how much backup and buffer stock to keep.

What this topic is

Supplier concentration is depending on one supplier for a critical input — a part, material, or service. It is the mirror image of customer concentration: this time the power sits with whoever you buy from.

Why it matters

A single supplier who raises prices, has a disruption, or fails can halt your production or force you onto their terms. One weak link in the supply chain can stop an otherwise healthy business cold.

Who should learn it

Anyone who makes or resells a product built from bought-in inputs — manufacturers, brands, restaurants, and anyone reliant on one platform or vendor to operate.

What you will understand

  • See how a single-supplier dependency can halt a whole business
  • Weigh the cheaper price of single-sourcing against its hidden risk
  • Use backup suppliers and buffer stock to bridge a disruption
  • Spot concentration in your supply chain before it bites

Prerequisites

Common misconception

"One reliable supplier at a great price is the smart, lean choice." Cheaper per unit, yes — but a single source means a single point of failure. The savings can be erased many times over by one disruption you could not absorb.
