How do order, warehouse and transport responsibilities differ?
Order management covers routing and fulfillment coordination. Warehouse management concerns inventory and warehouse execution. Transport management covers carrier, serviceability and delivery coordination. Your operating model determines the handoffs between them.
What should we bring to a fulfillment walkthrough?
Bring a typical order and an exception, such as unavailable stock or a failed delivery. Show the teams, systems and status updates involved so the proposed workflow can be assessed against actual work.
Can existing fulfillment systems remain in the plan?
Include them in the requirements. Map their responsibilities, interfaces and status definitions, then assess which connections are needed and which changes would be required before committing to a rollout approach.
