Therefore for multi-product environments kanban requires substantial inventory to achieve the necessary throughput. Kanban is a tool for realizing just-in-time. For this tool to work well the production process must be managed to flow as much as possible. Other important conditions are levelling production as much as possible and always working in accordance with standard work methods. Some kanban rules are as follows 1. The earlier process produces items in the quantity and sequence indicated by the kanban. 2. The later process picks up the number of items indicated by the kanban at the earlier process. 3. No items are made or transported without a kanban. 4. Always attach a kanban to the goods. 5. Defective products are not sent to the subsequent process. The result is 100 defect-free goods. This method identifies the process making the defectives. 6. Reducing the number of kanban increase their sensitivity. This reveals existing problems and maintains inventory control. The kanban system is most likely to be associated with just-in-time JIT systems and the theory of constraints TOC . The success of kanban systems appears to depend heavily on complete implementation. Even in cases where the implementation is complete kanban systems are unable to cope with product variety and demand fluctuation. It may be that when kanban is used as part of a continuous improvement programme as with JIT philosophy it is likely to produce increased benefits to the user. Bibliography 1.
