In nature two similar things are difficult to obtain. If at all we come across exactly similar things, it must be only by chance. This fact holds good for production process as well. No Production process is good enough to produce all items of products exactly alike. Every production process is subjected to some degree of natural variability for which chance and assignable causes are there .A control chart is a graphical representation of the collected information. It detects the variation in processing and warns if there is any departure from the specified tolerance limits. The control limits disclose the variability causes i.e Chance and Assignable. The Control Charts described in this paper gives the details about need, types & procedure of implementation.
