I am on a project building a new enterprise resource planning system. My supplier is every part of the business that wants to supply the new system with data to be used, for example the Planning organisation. They want to be able to put an order into the system, which will trigger the product to be made and shipped. The customer of this system could be a function in the business like manufacturing, who will receive planning’s request for an order and use that to know what to make. Additionally, traceability is a customer who will use the data embedded in the system to support regulatory requirements. All this underpins the ability to supply patients with medicine, as the system will be a repository of data for all global processes.
