Focuses on the Customer
► The Customer is the ONLY one who defines the
VALUE of the product.
► Customers support suppliers who best meet their
needs with additional business
► Anything not adding Value to the product is WASTE.
► Ask yourself:
► Would the Customer pay for this?
Waste is:
- anything that takes time, resources or space but
does not add value to the product or service
delivered to the customer.
Lean :
