BU395 Chapter Notes - Chapter 15: Shingo Prize For Operational Excellence, Lean Manufacturing, Operations Management
Document Summary
Little just-in-time (jit) is a production system in which processing and movement of parts/modules/work-in-process occur just as they are needed, usually in small batches. Big jit, also called lean production is a philosophy of waste reduction and continuous improvement. Mrp controls the work centre capacities, whereas jit controls the inventory (through kanbans). The main benefits of jit/lean can be discerned from the results section of shingo prize: quality (internal quality, quality to the customer), delivery (lower lead time, on-time delivery), cost/productivity (labour productivity, inventory turns, etc. As an example, consider flex-n-gate, toyota trucks bumper manufacturer (see the mh. Flex-n-gate became more flexible: more easily meeting toyota"s changing orders; became more productive: reduced its die set up times and wip inventories; and improved its employees" morale: worker involvement. The principles of shingo prize are fundamental rules or guidelines for becoming lean (i. e. , its implementation), whereas goals of jit/lean are its objectives.
