This process group covers how an organisation buys what it needs, from category strategy through to ongoing supplier performance. It starts with sourcing governance: a procurement plan, clarified requirements, contingency cover for materials, matching needs to what the supply base can deliver, spend profiling, efficiency and value opportunities, and joint sourcing work with suppliers. It then covers choosing suppliers, certifying and validating them, negotiating contracts and administering those contracts over their life. Ordering follows, from requisition review and approval through quoting, purchase order issue, expediting, reconciliation and resolution of exceptions. It closes with supplier management: keeping supplier information current, analysing procurement and supplier performance, supporting inventory and production needs, and checking the quality of what is delivered.
