In category management, grouping is most effective when based on similar usage characteristics . This means materials or services are categorised by how they are used within the organisation, rather than simply by spend or supplier. For example, in healthcare, personal protective equipment (PPE) forms one category, while surgical instruments or bedding may be separate categories. This approach ensures that category managers have a clear understanding of functional requirements, demand patterns, and value drivers. Grouping only by spend might overlook strategic importance, while grouping by supplier or geography can miss opportunities for cross-functional efficiencies. Usage-based categorisation allows for tailored procurement strategies that align with business objectives and ensure effective stakeholder engagement. It also enables organisations to identify synergies across business units and improve supplier management. By aligning categories to organisational needs rather than just financial or structural dimensions, procurement creates more value and achieves better alignment with corporate strategy.
