Eliminating the WastesValue Added
Typically 95% of all lead time is non-value added
1. Overproduction2. Waiting3. Transportation4. Non-Value Added Processing5. Excess Inventory/Material6. Defects7. Excess Motion8. Underutilized People
Non-Value Added

The 8th WasteNot utilizing operators to their full potential
Lack of cross-functional trainingOver relying on a select few while others are Inadequately trained
Operators are unable to rotate and help each other out to balance the work-load
High overtime, increased pressure stress
ProcessValue Added
Adds value to the output and
customer is willing to pay
for.
Optimize
Non-Value Added
Does not add value to the output, and
customer isn’t willing to pay
for.
Eliminate
Business-Value Added
Does not add value to output, customer will not pay for, but
is necessary.(Legal, Safety, Etc.)

•What operation controls the cycle?•How can you relieve the bottleneck?
Basic Lean Concepts
• Maintain buffer in front of bottleneck – (never starve the bottleneck !)
• Improve bottleneck operation• Cross train on bottleneck
–Creates a visual work place–Continuous Improvement–Cell Support–Balance activities / operations
