* What Process improvements will be necessary? Setup HEY, EVER HEAR OF KAIZEN? 这里曾做过改善吗 ？ * Future Value Stream Mapping * Future State Design Concepts理念 What is the Takt time? Will you build to a finished goods supermarket, or directly to shipping? Where can you use continuous flow processing? Where will you need to use supermarket pull systems to control upstream processes? Key Questions * Future State Design Concepts 5. At what point in the production chain will you schedule? (pacemaker标兵) 6. How will you level the production mix at the pacemaker process? 7. What increment增加 of work will you consistently release and move at the pacemaker process? 8. What process improvements will be necessary for the value stream to flow as your future-state design specifies说明? Key Questions * Example of building to a supermarket: Customer Requirement Shipping Assembly Example of building directly to shipping: Customer Requirement Assembly Shipping * Where can we introduce continuous flow? Press Sub Assy 1 Mark Assemble Sub Assy 2 1.5 s 40 s 71 s 54 s 59 s Notes: The press process cycles very quickly and changes over to serve several product lines. So incorporating成为一部份 it into a continuous flow would mean slowing its cycle time and dedicating贡献 its capacity. This would result in an under-utilized press and a need to buy another to serve other product lines. Therefore it makes sense to run the press as a batch operation and control its product with a supermarket-based pull system * Notes: The other operations are not far apart离得很远 in time and near TAKT. They can easily be dedicated贡献 to this product family. This makes continuous flow possible. The desired期望 state would be to place these processes adjacent邻近 to each other, implement one-piece flow and Distribute分配 work elements so that each operator’s work content工作量 is below TAKT Where can we introduce continuous flow?
