Hi Srinivasan, 

 

I presume you are referring to something like productivity. If that is the case, it is not feasible to have upper control limit but you may not have an upper specification limit. Specification limit is a value beyond which the outcome is called defective. 

 

Hope this helps. 

Mr VK,

 

Yes, it is about the training batch output %.i am trying improve the output % for more man power for the production floor and initiating a GB project on the same.

 

Thank you for the explanation.
