Learning to see notes

##What do you typically see?

  • 80 – 90% of total steps are waste from standpoint of end customer
  • 99.9% of throughput time is wasted time
  • Demand becomes more and more erratic as it moves upstream, imposing major inventory, capacity, and management costs at every level
  • Quality becomes worse and worse as we move upstream, imposing major costs downstream
  • Most managers and many production associates expend the majority of their efforts on hand-offs, work-arounds, and logistical complexity

##Objective

  • Correct specification of value
  • Elimination of wasteful steps
  • “Flow where you can”
  • “Pull where you can’t”
  • Management toward perfection

##Process

  1. Select one value stream - a product family
  2. Walk the physical flow of material – no data collection
  3. Walk the flow again, collecting data
  4. Draw the Current State Map
  5. Identify opportunities to eliminate waste and create flow
  6. Draw the Future State Map
  7. Generate a Value Stream Plan
  8. Start making the improvements
  9. Conduct Value Stream Reviews
  10. Repeat the cycle

Begin at shipping and work upstream. Prevents idealist walk of the stream - trace the contributing actions backwards. If you hit a block work from upstream downwards.

##Waste

  • Overproduction
  • Waiting
  • Transportation
  • Unnecessary Processing
  • Inventory
  • Unnecessary Motion
  • Correction
