Thank you Kumar for sharing this step by step guide.
I have never ever worked on SPC and it still remains a mystery for me. Your document is very helpful in understanding the basic steps and it will definitely a helpful for me whenever I get to work in this.
I was able to understand most of the content but couldn't understand the Control chart type logic. How do we get to know what type is needed? I have no idea ! I expect a single statement response because you know, its not the place to start a discussion 🙂
