Supplier segmentation
Supplier tiering
Supplier segmentation is the grouping of suppliers according to criteria such as spend, business impact, supply risk, dependency, innovation potential or strategic importance so that management effort can be proportionate.

Simply put
What it means in ordinary work
It decides which suppliers need close attention and which can be managed through standard processes. The model should reflect the organisation's real exposure, not only spend size.
Why it matters
Managing every supplier the same way wastes effort and leaves critical relationships under-managed. Segmentation helps allocate governance, reviews and development resources.
A hypothetical in practice
A hypothetical manufacturer segments suppliers into strategic, collaborative, transactional and managed-risk groups. The top group receives joint improvement plans and executive reviews, while low-risk suppliers use a catalogue and automated ordering.
Common pitfalls
High spend does not always mean high risk or strategic importance. Include dependency and criticality.
Segments can become labels that are never revisited. Review them when the business or market changes.
