##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
- Select one value stream - a product family
- Walk the physical flow of material – no data collection
- Walk the flow again, collecting data
- Draw the Current State Map
- Identify opportunities to eliminate waste and create flow
- Draw the Future State Map
- Generate a Value Stream Plan
- Start making the improvements
- Conduct Value Stream Reviews
- 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
