Instruct operators to perform more than one operation in a product flow-oriented setup (see illustration). Operators should be trained to operate different types of machines (such as benders AND crimpers AND testers) so they can guide products through cell setups (also called cross-training ).

An example of performing multiple operations. The operator operates different types of machines in a cell:
