The paper describes the implementation of process management methodology SCOR in a retail company. The supply chain operations reference model (SCOR) provides process management methodology, including processes, their metrics, benchmarking and diagnostic tools to assist an organisation in enhancing supply chain processes. The model contains multiple sections and is composed of management processes, such as Plan, Source, Make, Deliver, Return and Enable. The model can be used to describe processes of supply chains that are simple or very complex using a common set of definitions. As a result, processes of companies from different industries can be measured against industry peers using the same metrics. The paper summarises important milestones and lessons learnt during implementation of SCOR in a retail company. It explains benefits of SCOR, as well as main challenges in the implementation of new process modelling framework.
