Zero defect is a Nirvana stage.
When there is no waste, no unwanted activities in process of making a product.
No matter how much money you invest, there will always be some waste generated/ some activity that is a not adding any value to the product.
You take any organization with world class equipment,processes, technologies. They are still struggling to achieve Zero Defect, because it is practically impossible.
I am not telling that Organization should stop working to achieve zero defect.
Considering "Zero defect" as a concept is brilliant. It motivates and drives people for continuous improvement.
If Zero defect is possible why do organization struggle to achieve 6sigma level. i.e 3.4 DPMO.
why don't they target higher sigma level where there is 0 DPMO.
six sigma is only one aspect of Zero Defect
