Runner, Repeater, Stranger Event

Which inventory should you stock? How much, of each type, should you store in raw materials, work in process, and finished goods? How often should you schedule production? What is your stocking strategy? 

These were the questions posed to a manufacturing company during a recent Runner, Repeater, Stranger Inventory Analysis engagement.

  • Have enough inventory to ship, consistently, to customers
  • Improve transparency of data and accuracy of information
  • Build more trust in the process and create a system they can all utilize and build
  • Increase profitability
  • More independence from factory orders

  • Lean overview training
  • Increased refresh rates for both inventory & spare parts from every 24 hours to every hour
  • Reviewed info inventory codes
