Definition: Supplier segmentation
Supplier segmentation describes the systematic division and classification of suppliers into different categories based on defined evaluation criteria.
Basic segmentation approaches
Classification is typically based on several dimensions that take into account both quantitative and qualitative factors. Key evaluation criteria include:
- Strategic importance and business volume
- Supplier performance and quality level
- Risk potential and degree of dependency
- Innovative strength and development potential
Supplier segmentation vs. supplier classification
While supplier classification is primarily based on static characteristics, segmentation takes dynamic aspects of the business relationship into account. Segmentation enables a more strategic approach to supplier management.
Importance of supplier segmentation in Procurement
As the basis for strategic purchasing decisions, segmentation enables targeted resource allocation and differentiated management approaches. It forms the foundation for effective supplier strategies and optimized business relationships.
Methods and procedures
Supplier segmentation is implemented in practice using structured evaluation procedures and established classification models.
Portfolio matrix approach
The classic approach uses a two-dimensional matrix that classifies suppliers according to procurement volume and strategic importance. Typical segments include strategic partners, development suppliers, volume suppliers and standard suppliers. This method enables a clear visualization of the supplier base and supports strategic decisions.
Multi-criteria evaluation models
Advanced segmentation approaches take multiple evaluation dimensions into account using weighted scoring models. Supplier evaluation is based on defined criteria such as quality, delivery reliability, innovation and cost position. Regular re-evaluations ensure that the segmentation is up to date.
Data-based segmentation methods
Modern approaches use analytics and AI-supported processes for automated segmentation. These methods analyze large amounts of data from ERP systems and supplier portals for objective classification and continuous monitoring of segment changes.

Key figures for managing supplier segmentation
Effective KPI systems enable the measurement and continuous optimization of segmentation quality and effectiveness.
Segmentation quality and stability
The segmentation quality is evaluated using key figures such as segment change rate, classification accuracy and evaluation consistency. A low segment change rate indicates stable classifications, while frequent changes can indicate evaluation problems. The documentation of segment changes supports the continuous improvement of supplier evaluation.
Allocation of resources by segment
The allocation of purchasing resources to different supplier segments is measured by key figures such as support intensity per segment, development effort and management time. These metrics show whether the distribution of resources corresponds to the strategic importance of the segments and support optimization decisions in supplier relationship management.
Segment-specific key performance indicators
Differentiated KPIs for different supplier segments enable targeted performance measurement. Strategic partners, for example, are evaluated on the basis of innovation contributions and cost savings, while standard suppliers are primarily assessed according to price-performance ratio. The segment-specific application of PPM targets supports differentiated performance management.
Risks, dependencies and countermeasures
The implementation and application of supplier segmentation entails various risks that can be minimized by taking appropriate measures.
Static segmentation and outdated classifications
One of the greatest dangers lies in the inadequate updating of segmentations. Outdated classifications lead to suboptimal management decisions and inefficient allocation of resources. Regular reviews and automated monitoring systems are essential. The integration of supplier scorecards supports continuous evaluation processes.
Subjectivity in evaluation criteria
Unclear or subjective evaluation criteria can lead to inconsistent segmentation results. Standardized supplier evaluation criteria and objective metrics reduce these risks. Training for evaluation teams and clear guidelines ensure uniform application of the segmentation logic.
Overcomplexity and resource expenditure
Segmentation models that are too detailed can increase the administrative workload disproportionately. A balance between level of detail and practicability is crucial. Focusing on key evaluation dimensions and using digital tools for supplier master data maintenance optimizes the cost-benefit ratio.
