* Take a look at OCT and determine how many operators would be in the cell if their amount of work was shared between all operators….3 should be the target. * This is how the operator load chart should look after a little kaizen to reduce total OCT from 187 seconds to 174 seconds. * Ask the question and have the class answer, then explain how it is shown on the future-state map. CLICK TO ANIMATE THE CHANGES TO THE MAP IN RED. List the Kaizen events needed to get to one-piece flow. SMED and standard work events would be needed to implement one housing cell. * See how much simpler the map gets by implementing one-piece flow. It reduces the numbers of process boxes and the complexity of information. It takes work to get there in reality, Three Kaizen events are needed to get to that level. * Ask the question and have the class answer, then explain how it is shown on the future-state map. CLICK TO ANIMATE THE CHANGES TO THE MAP IN RED. The pull systems would be at finished goods and a the stamp area. * Ask the question and have the class answer, then explain how it is shown on the future-state map. CLICK TO ANIMATE THE CHANGES TO THE MAP IN RED. The housing cell would pull stamped housings in batches of 60 with a transport card, and the production card would go to stamp. What lot size would stamp want to run? * Ask the question and have the class answer, then explain how it is shown on the future-state map. CLICK TO ANIMATE THE ANSWER. Since stamp has a one hour changeover, it would not be able to support a lot size of only 60 pieces. * Ask the question and have the class answer, then explain how it is shown on the future-state map. CLICK TO ANIMATE THE CHANGES TO THE MAP IN RED. It would work better if a batch of kanban were collected at stamp and when the set-up wheel comes around to that part, the stamp machine would run the required quantity represented by the cards that were collected. * Ask the question and have the class answer, then explain how it is sh
