Unnecessary effort (production or communication) which adds no value to a product or service. Doing more than the minimum to transform material into product to meet customer expectation.

Causes for Extra Processing:

Ø Processing design decisions made at inappropriate levels
Ø Poorly documented processes
Ø Lack of customer input concerning requirements
Ø Poor configuration control
Ø Bogus quality standards (Not related to customer)
Ø No estimation of Voice of Customer
Ø Undue reference to old designs
Ø Wrong version

Solution for this waste:

Ø Think “small is beautiful”.
Ø Smaller machines avoid bottlenecks, improve flow lengths.
Ø Generate Voice of Customer
Ø Account all operations with the customer requirements
