Difference between Tolerances and Control Limits (PMBOK Page 250)
Quite confusing. Are they not the same? Could you please give a example so that i can visualize?
Thanks,

Quality Management - Control Quality
Re: Quality Management - Control Quality
I think this is pretty straight forward. Basically both are limits but intended for 2 different things
Tolerance - This is to make sure the product produced is with in limits defined. For example, screw's specification limits foo gauge may be
Control limit - this is to make sure the process is within specified limit. E.g. the screws produced today is all within control limits. So our manufacturing process is quite stable.
So the key is one is for product and other for process
