When segmenting suppliers, it's important to define criteria that are tailored to your business goals, challenges, and opportunities. You can use spend, criticality, performance, risk, and innovation as criteria to score and rank your suppliers. Spend refers to the amount spent annually with each supplier, while criticality is the importance of each supplier for core products or services. Performance looks at how well each supplier meets quality, delivery, and service standards. Risk assesses the vulnerability of each supplier to disruptions, compliance issues, or market changes. And innovation evaluates the contribution of each supplier to your innovation and differentiation. Different weighting factors can be used to reflect business priorities and objectives.
