Definition: Supplier evaluation criteria
Supplier evaluation criteria are systematically defined benchmarks for the objective assessment of suppliers in various performance dimensions. They serve as the basis for well-founded decisions in supplier selection and continuous performance monitoring.
Core elements of the evaluation criteria
The most important evaluation dimensions include:
- Quality criteria: Product quality, certifications, error rates
- Cost factors: pricing, total cost of ownership, cost development
- Delivery performance: adherence to delivery dates, flexibility, capacities
- Service & support: response times, technical support, communication
- Sustainability: environmental standards, social responsibility, compliance
Differentiation from other valuation methods
In contrast to simple price comparisons, structured supplier evaluation criteria take multiple dimensions into account and enable a holistic view. They differ from ad hoc evaluations due to their standardization and traceability in supplier management.
Importance in strategic Procurement
Professional evaluation criteria reduce procurement risks, improve supplier quality and create transparency for internal stakeholders. They form the basis for supplier development and strategic partnerships.
Methods and procedures
The implementation of effective supplier evaluation criteria requires structured methods and proven procedures. Modern approaches combine quantitative metrics with qualitative assessments.
Weighting models and scoring procedures
Successful evaluation systems use weighted scoring models in which various criteria are evaluated according to their strategic importance. Typical weightings are quality (30%), costs (25%), delivery performance (20%), service (15%) and sustainability (10%). The supplier scorecard documents these evaluations systematically.
Data collection and validation
Reliable assessments are based on valid data sources:
- Quantitative KPIs from ERP systems and incoming goods inspections
- Qualitative assessments through supplier audits and on-site visits
- External data sources such as credit checks and certifications
- Feedback from internal stakeholders and end customers
Continuous evaluation and adjustment
Modern evaluation systems work with regular review cycles and automated alerts in the event of critical deviations. Quarterly business reviews enable criteria to be systematically reviewed and adapted to changing market conditions.

Key figures for controlling supplier evaluation criteria
Effective management of supplier evaluation systems requires meaningful KPIs that measure both the quality of the evaluations and their business impact. These KPIs enable continuous optimization of the evaluation processes.
Valuation quality and consistency
Key performance indicators for measuring evaluation quality include evaluation coverage (proportion of evaluated suppliers), evaluation frequency and consistency between different evaluators. The standard deviation for multiple evaluations of the same supplier shows the objectivity of the system. Audit scores validate the assessment accuracy through independent audits.
Performance correlation and prediction accuracy
The correlation between evaluation results and actual supplier performance measures the predictive power of the system:
- Correlation coefficient between score and delivery performance
- Hit rate for risk forecasts (sensitivity/specificity)
- Stability of the valuations over time
- Deviation between forecast and actual performance
Business impact and ROI of the valuation
Business-oriented KPIs demonstrate the value contribution of systematic supplier evaluation. These include cost savings through optimized supplier selection, reduced downtimes and improved quality indicators. The efficiency of the evaluation process is measured by costs per evaluation and throughput times.
Risks, dependencies and countermeasures
The implementation of supplier evaluation criteria involves various risks that can be minimized by taking appropriate measures. A conscious risk assessment is essential for successful evaluation systems.
Subjectivity and evaluation bias
Unclear criteria or inadequate training can lead to subjective assessments and systematic distortions. Countermeasures include standardized evaluation guidelines, regular calibrations between evaluators and the integration of objective data sources. Supplier audits by trained auditors significantly reduce these risks.
Data quality and availability
Incomplete or outdated data jeopardizes the validity of valuations. Critical dependencies arise due to:
- Poor integration between IT systems
- Delayed data update for suppliers
- Lack of validation of external data sources
- Insufficient documentation of valuation principles
Strategic mistakes due to one-sided focus
Excessive weighting of individual criteria can lead to suboptimal supplier decisions. Risk management requires balanced evaluation models and regular reviews of the criteria weighting. Supplier segmentation helps to develop category-specific evaluation approaches.
