Without supply chain our lives today would hardly be the same. Companies and organizations profit from higher cost efficiency and turnover, consumers profit from more affordable products and services to name just a few of the advantages supply chain brings. There are many different business processes in the supply chain which work together to achieve these advantages. This booklet provides an overall explanation of the business processes in the supply chain and how they are interlinked with each other. It is a guide for everyone who wants to understand the supply chain in its completeness. The business process diagrams of the processes described are available for download at www.criticalea.com/supplychain.
