Supplier Segmentation
How to segment a supply base so governance effort lands where it changes outcomes.
By SupplyChain.management · Last updated
Definition
Supplier segmentation classifies suppliers by spend, risk and strategic importance so that governance, measurement and relationship effort are proportionate.
Why it matters
Most organisations manage all suppliers the same way, which means the critical few get too little attention and the tail gets too much.
Example
Of 900 suppliers, 12 strategic partners hold quarterly business reviews, 80 key suppliers get monthly scorecards, and the remaining tail is managed transactionally.
How to interpret it
If your top suppliers are not visibly managed differently from the tail, the segmentation exists only on paper.
How to improve it
Score suppliers on spend, switching difficulty and risk exposure, then define a governance model per segment and hold to it.
Common mistakes
Segmenting by spend alone, which misses low-spend single-source suppliers that can stop production.
