Supplier segmentation

Definition

Supplier segmentation classifies the supply base, often along spend and supply-risk axes (Kraljic-style), into categories such as strategic, leverage, bottleneck and routine. The segment dictates the sourcing approach, contract type and relationship intensity, so scarce procurement attention goes where it adds most value.

Example

A single-source bottleneck supplier gets a continuity plan and buffer stock, while routine office supplies move to a self-service catalogue.

Why this is a business risk

Treating all suppliers identically wastes procurement capacity on low-value relationships while under-governing critical dependencies. A single-source strategic supplier that fails or is poorly managed can halt production, yet organisations without segmentation often discover this exposure only when a disruption is already underway.

How to manage it

• Plot suppliers on a spend-versus-risk matrix and assign each a segment before allocating governance effort.
• Define a distinct management approach for each segment: strategic suppliers get regular executive reviews, routine suppliers get a catalogue.
• Refresh segmentation at least annually and whenever spend patterns or supply risk change materially.
• Build contingency plans and alternative suppliers for bottleneck and strategic segments.
• Use segmentation outputs to set contract type and term length, matching commitment to strategic importance.
