This logistics data flow diagram depicts the processes and sub-processes required for goods to travel through an organization to the customer step-by-step. Logistics processes should be well-documented, defined, and regularly reviewed to achieve cost-effectiveness and meet SLAs for customer delivery. The use of logistics data flow diagrams and process modeling can benefit each sub-process throughout the logistics management function. Flow charts and workflows can be useful in various areas, including logistics planning, transportation, fleet management, and last mile logistics. Modeling these processes is a great place to start when it comes to improving logistics management productivity and efficiency, which usually results in lower costs and happier customers.
