In this tough market, the target of this study, Company W, is the leading producer of digital camera, is bound to streamline its supply chain management to reduce inventory costs, in order to sustain its competitiveness.
This study attempts to tackle the inventory problem faced by Company, in particular, the JIT and VMI inventory. Preliminary analysis reveals managerial issues, including inefficient JIT operations, passive VMI operations and lack of coordination with the supply chain information system. This study proposes to reengineer its JIT, VMI, PLM, SCM and BPI operations, and introduce more integration among various job functions. These enable Company W to reduce its inventory costs down to a reasonable level. In addition, these changes have to be institutionalized into its SOP, to ensure smooth JIT and VMI operations, and to prevent human errors resulting in improper inventory levels.
Furthermore, this study also suggests changes in the supplier evaluation process for better management of the supply chain. For inclusion into the new suppliers list, these include the willingness and support capacity and in computerization of the operations. For existing suppliers, quarterly evaluation has to be conducted properly, emphasizing impartiality and objective data, in order to assess their ability to undertake the development of new models. Suppliers with poor performance would be discontinued. The JIT and VMI operations for Company W are expected to improve through implementing the proposal.
