Design an end-to-end SOP for last-mile dispatch in [Region] for a [NetworkType] operation, optimizing for service and cost. Output format: 1) SIPOC (Suppliers, Inputs, Process, Outputs, Customers). 2) Standard Work Instructions with takt/touch times for planner, dispatcher, and driver roles. 3) Exception Playbooks for failed delivery, address issues, capacity shortfall, and on-road incidents. 4) Visual Management Pack (kanban, andon/escalation triggers, control charts for [KPI1] and [KPI2]). 5) RACI Matrix by role. 6) Change Control Checklist and training/competency sign-off. Calibrate staffing using arrival patterns and route density; define batching windows, cut-off times, and driver start wave logic. Specify system checkpoints in TMS/driver app (geo-fence events, proof of delivery, photo capture). Provide measurable acceptance criteria and an embedded audit checklist aligned to safety/regulatory constraints.
