The 5 Principles of Lean Thinking

  • Define value from the customer perspective

    • How do we define value?

      Must pass all three criteria;

      • Customer has to care (willing to pay for)

      • Must change the thing,

      • Done right the first time.

  • 95% Waste


Seven Forms of WasteAdd Costs but Not Value!

  • Transportation

  • Inventory (Unnecessary)

  • Motion (Unnecessary)

  • Waiting

  • Overproduction

  • Overprocessing (Inappropriate)

  • Defects
