Purchase Request Approval BPMN

A purchase request approval BPMN diagram shows the handoff from the person who needs an item to the manager who approves spending and the buyer who places the order. Lanes make those responsibilities visible. The approval gateway records the point where a request either stops or moves into procurement. Keep the request, review, decision, and order tasks short so people can scan the process during training or process review. Add finance, budget, supplier, or receiving steps only when they reflect the actual process. This is a workflow map, not a purchasing policy or a substitute for delegated approval limits. Keep the posted drawing current whenever the layout, equipment, or approved route changes.
