Design and Improvement of Service Processes—Process Management  347

        may be short, such as a few feet, or extremely long, as in moving items from
        one continent to another. The goals of logistics processes typically are to
        minimize damage and loss of items, to reduce costs involved, and to increase
        the response time for moving items around.


        Typically there are different modes for the transportation aspects of logistics;
        certain items may be moved by air, sea, or over land by truck or rail.
        Depending on the items being transported, these methods each have different
        attributes regarding cost, speed, and damage potential. Process management
        can be very useful in improving the performance of these processes.
        For example, in France, the Minitel system, which resulted from a process
        management study, has reduced logistics and shipping costs through better
        coordination between the different trucking companies. The Minitel system
        helps pair up shipments and trucks so that trucks returning to their original
        point of origin, which may have returned empty, are now being subcon-
        tracted to carry other items, thereby avoiding the need for extra round-trips.

        Logistics and Distribution Processes Performance Metrics

        Shipment Damage or Loss
        Loss or damage of shipped items is clearly a key failure for a logistics and
        distribution process. Loss of items may be caused by poor handling, failure
        in a shipment tracking system, or failure in a sorting process or of equipment.
        Damaged items are mostly due to poor handling or packaging. Clearly, it is
        desirable to reduce shipment damage and loss to a minimum.


        Delivery Delays
        Delivery delay means that the items arrive in a customer’s hands later than
        promised. It clearly makes customers unhappy and damages the shipper’s
        credibility. Delivery delay may be caused by poor handling, poor shipment
        tracking, inadequate shipping capacity, bottleneck resources, and poor
        scheduling.

        Logistic Cost
        Logistic and distribution costs depend on many factors. The important
        factors include scheduling and routing, location and capacity of distribution
