D?iscuss the interaction between purchasing and supply management and the operational groups in a manufacture or service organization-in particular product design, quality management, forecasting/planning, project management and inventory control. To what extend does purchasing and supply management participate in the use of Manufacturer resource planning (MRPII) or enterprise resource planning (ERP) in the private sector? What is the role of purchasing and supply management in the development of supply chain strategy for a manufacturing organization. I need a full page of written answer, if any graphs or chart are available needs to be added to the page. I appreciate your support.
