12 Operational Excellence When each and every employee can see the flow of value to the customer, and fix that flow before it breaks down. SM Kevin J. Duggan

13 The Eight Steps to Achieve Operational Excellence 1. Design a lean flow using lean guidelines. 2. Implement a lean flow. 3. Make the lean flow visual. 4. Create standard work for the lean flow. 5. Make abnormal flow visual. 6. Create standard work for the abnormal flow. 7. Teach employees to maintain and improve the flow to the customer. 8. Free management to work on offense.

23 Welcome to EMC Supply Co. In today s class we will visit the Electro-Motion Control (EMC) Supply Co. EMC Supply Co. builds a wide variety of products for the motion control and electronics industries. They supply distributors and end users. They also build custom products to order. The management at EMC Supply Co. have stated that want to achieve self-healing value stream flow in their high mix environment.

39 Interval for the Mix In a mix environment we must define the Interval in which the pacemaker will run the mix of products. The concept of the interval must be clearly understood. You may have hear the term EPEI which stands for Every Product Every Interval.

40 The Interval

41 The Interval 1 Week

42 1 Day The Interval

43 Is there Enough Time for Changeovers? We would compare the total time needed to the effective working time per interval. Any left over time can be used for changeovers. Time left for changeovers 100 min. 10 Products in the Family Max C/O time = 10 min. Time Machine station Effective working time per interval 900 min. Total time needed per interval 800 min.

51 Balancing Flow for the Mix Since the labor content varies and not all products can be balanced to takt time, we must decide the best way to balance the products based on our business. Let s look at balancing options

52 Option # 1: Discrete Parts Low Demand Variation High Volume # Operators always constant Output varies based on work content Level mix, sequence orders based on work content and pull signals Pacemaker seconds Balancing Examples Level the schedule and keep labor constant, build products in order: A C B A C B A C B FIFO Seconds Test Ship

53 Option # 2: Discrete Parts Custom Parts High Demand Variation Short Lead Times Build to demand as much as possible Output constant, labor varies A C B C C B Pacemaker 110 seconds Balancing Examples Balance to the takt time and add labor when a product exceeds the takt time. Try to build products to demand. FIFO Prod Control Test s AWCT=110s FIFO Ship Customer demand Small overflow of main products when mix is exceeded

57 By Standard Work we mean that any operator following a prescribed method, with a proper workstation, and proper tools, should be able to perform the amount of work required in the same amount of time, without risk to health or safety. Creating Standard Work

59 Pitch is targeted to be: Takt time x something (ex. Pack size) Establishing Pitch How can we create pitch when the pack size is different for each product?
