Question 4: Can we start to introduce SPC without any preparation?

Yes, you can! You can start thinking SPC right away, and that alone can lead to substantial savings. On the other hand the capability index you get, for example if your measurement system is not accurate enough, may not match reality.

Question 5: What is MSA?

MSA stands for Measurement System Analysis; it is a way of evaluating spread in the measurement system in relation to tolerance, or better still in relation to process spread. If the measurement system varies very much compared to the process, there is a great risk of assuming that the process setting has changed, when what you are actually reading is variation in the measurement system.
