Logistics and Supply Chain Management




                    Notes          functions as a single entity. Supply chain synchronization is the ability to coordinate, organize
                                   and manage end-to-end supply chain  flows – including products,  services, information and
                                   financials – in such a way that the supply chain functions as a single entity. In other words, it is
                                   a shared objective for supply chain members who are willing to work together to determine
                                   how best to perform the overall activities and tasks that are required to meet customer demand.
                                   With synchronized supply chains, the overall goal is the same as with traditional supply chain
                                   management.
                                   There are three key differences, however. One is that companies work with their vendors in
                                   order to coordinate their processes and to achieve simultaneous production. Another difference
                                   is that the Internet and other types of technology are incorporated into the process to make those
                                   processes run smoother and more efficiently. Finally, the buying organization will need to hire,
                                   train, and restructure their workforce in order to be able to accommodate this type of supply
                                   chain management.

                                   Synchronization enables companies to anticipate demand disruptions and anomalies in a timely
                                   manner in order to mitigate the infamous bullwhip effect. It helps firms move to a demand-
                                   driven environment  that is better equipped to deal with uncertainty. Typically supply chain
                                   managers handle uncertainty through buffering – i.e., it maintains pools of inventory at multiple
                                   places in the supply chain. A synchronized supply chain operates by separating baseline demand
                                   from demand surges and then using strategic points in the supply chain for the placement and
                                   use of capacity and inventory.
                                   Firms that aren’t synchronized often find that they have higher costs than firms and supply
                                   chains that have some degree of synchronization in their supply chain. The higher costs can
                                   result from  inefficiencies in  everything  from  manufacturing change  orders to  expedited
                                   transportation costs. A cost that is not often known due to the lack of synchronization, however,
                                   is the total cost due to excess inventory carried by supply chain members in an attempt to cover
                                   their exposure to risk.

                                   Simply recognizing that a firm is operating in a reactive mode does not guarantee that necessary
                                   changes will be made. That is, firms will not necessarily make the needed investment in improving
                                   synchronization unless organizational behaviour, management  processes and  technological
                                   infrastructure issues are addressed. Changes to these areas will not happen unless management
                                   is convinced that doing otherwise would be detrimental to the wellbeing of the firm. To achieve
                                   the ideal state of synchronization, a firm must consider an even broader perspective. It is not just
                                   what is good for the firm, but rather what is best for the many members of the entire supply
                                   chain.

                                   2.6.1 Performance Cycle Structure

                                   The performance cycle represents  the elements  of work  necessary to complete the  logistics
                                   related to market distribution, manufacturing, or support procurement. It consists of specific
                                   work ranging from  identification of  requirements to  product delivery.  Because it  integrates
                                   various aspects of work,  the performance cycle is  the primary unit of analysis for logistical
                                   synchronization. At a basic level, information and transportation must link all firms functioning
                                   in a supply chain. The operational locations that are linked by information and transportation
                                   are referred to as nodes. In addition to supply chain nodes and links, performance cycles involve
                                   inventory  assets. Inventory is measured in terms  of the asset investment  level allocated  to
                                   support operations at a node or while a product or material is in transit. Inventory committed to
                                   supply chain nodes consists of base stock and safety stock. Base stock is inventory held at a node
                                   and is typically one-half of the average shipment size received. Safety stock exists to protect
                                   against variance in demand or operational lead time. It is at and between supply chain nodes
