Better quality – Very defined setup processes ? Lower cost – Less scrap and inventory ? Better flexibility – Rapidly change from product to product ? Better worker utilization – Less time spent on setup or waiting for the run to start ? Shorter lead time and more capacity ? Less process variability 15 ? It is a customerdriven requirement. Customers are demanding: – Product and service diversity – Lower costs – Higher reliability and quality. ? So anizations must: – Produce smaller lots, more frequently. – Expand the scope and diversity of products – Reduce quality defects. 16 ? Setup is given and fixed ? Therefore, – Use highly skilled setup personnel – Minimize product variety – Combine lots – Make large batches 17 ? Setups CAN be improved! ? Small lot production REQUIRES short setups ? Setup time reduction of 90% and more is mon 18 1. Preparation – Ensures that all the tools are working properly and
