Lean six sigma eliminates non-value added activities in the organization. Should it be considered a core requirement/ prerequisite for professionals?

Lean six sigma principles are usef for many years to improve the business processes. It is an effective way to eliminate wastes (muda) Here you can find information related with it

I think lean six sigma eliminates non value added activies in the organization because if these non value added activities are eliminated it creates

• Value
• Indentifies the value system
• Makes the flow efficiently by removing the unwanted steps
• Gives enough time(Buffer) for the critical path
• Final outcome will be perfect.(that Is it may be Final Product, Time to be completed etc.)

I think Lean management skill will definitely added advantage for the professional in a production environment, not only production, it will be helpful in refining the process by cut short or eliminating the unwanted things so that to proceed with the things in a efficient manner. I think it is considered to be a requirement.  Thanks.
