Delivery Delay Issue Tree

Delivery delay issue tree

This issue tree breaks late deliveries into supply and fulfilment. Supply covers whether materials arrive in time for production. Fulfilment covers whether completed orders are picked, packed, dispatched, and carried to the customer on time. The split makes it easier to assign owners and find the constraint instead of treating a late delivery as one undifferentiated problem. Use timestamps from purchase order, production, warehouse, dispatch, and proof of delivery to test the branches. Add order-entry quality if incorrect promises or address problems are frequent. The leaves should be measurable operational hypotheses, not broad labels. It gives readers a concise reference they can reuse when discussing the result with colleagues.
