Progressive Bundle System: Each operation is done by a single worker operating a stationary sewing machine. Each worker receives a bundle of unfinished garment. Worker then performs a single operation on each garment. This system creates high level of Pace and labor productivity. The side effect is creation of huge WIP inventory. 90% of times inventory is sitting for worker to act upon.
Modular Production System: This groups tasks and assigns them to members of a module. Although most operators in the module still spend the majority of their time on a single assembly task, opeators do move to other tasks if work is building up at some other step. Compensation is based on module’s output. Modules are partially self directed and operators determine task assignment, pace and output targets. This systems reduces the buffers between assembly steps.
