Supplier segmentation groups suppliers into management categories using factors such as business impact, supply risk, substitutability, innovation potential and relationship complexity. It helps a company decide which suppliers need transactional oversight, active performance management, development or strategic governance.
Which factors are used?
Common inputs include spend, criticality, switching time, market concentration, operational dependency, data access, regulatory exposure, performance and future value. Spend alone should not determine the segment.
How are segments defined?
Each segment should have an explicit purpose and management model. For example, a critical supplier may require continuity planning and executive reviews, while a routine supplier may be managed through standard service measures.
How is segmentation performed?
Normalize the supplier record, assess the approved criteria, review edge cases with business owners and assign the segment with evidence. Record effective date and reviewer.
How does segmentation affect supplier management?
The segment can determine review frequency, scorecard depth, risk monitoring, contract attention, improvement activity and relationship ownership.
When should a segment change?
Reassess after major demand, contract, ownership, performance or market changes. Avoid permanent labels that no longer reflect the dependency.
