Supplier Diversification

A supplier you've never ordered from isn't a backup — it's a bookmark. Real diversification is qualified with orders, enabled by portable specs, and built in calm weather.

What decision this helps you make: Which SKUs earn a second source, whether backup or continuous split fits each, and whether your specs are portable enough to make either possible.

What this topic is

Supplier diversification is the operational build of a second source: real-order qualification, portable specs (the prerequisite most sellers lack), and the allocation choice between a qualified backup and a continuous volume split.

Why it matters

The risk lessons said WHY single-sourcing is exposure; this is the HOW — and the how has real costs (split discounts, duplicate tooling, doubled QC) that make selectivity the discipline: diversify the flagged SKUs, not the catalog.

Who should learn it

Anyone whose concentration table flagged a supplier share — and anyone whose "backup supplier" has never actually shipped them anything.

What you will understand

  • Qualification means orders: samples, then production — never first-tried in an emergency
  • Spec portability: why the incumbent's institutional memory is your switching cost
  • Backup vs. split: the allocation decision and its tradeoffs
  • Selectivity: which SKUs earn the dual-sourcing tax

Prerequisites

Common misconception

"We have a backup supplier — I've got three factories bookmarked and one even sent samples." Samples prove a factory can make one careful unit; production proves it can make thousands under deadline. A backup that's never run a real order is a hypothesis wearing a contingency plan's name — its minimums, lead times, true quality, and communication style are all unknowns you'd be discovering during the exact crisis that made you need it.
