Statistical Process Control involves different types of actions. To sum up in short way, while applying SPC to company’s real process the following actions was taken:
- Taking actions on the process. This comprises the Voice of the Process identification by using Control Charts. It can be considered as a first step to process improvement as it recognize assignable causes of variation.
- Taking actions on the process outcomes. This involves the Voice of the Customer identification. Here a person needs to separate acceptable outcomes from unacceptable.
- Taking actions to align the two voices. As a result of two previous actions, now a person seeks to compare the voice of the process with voice of the customer.
To my mind, this is a basis of SPC and those simple actions can be applied to almost any process. Now, I can easily understand those people in the companies, who put every action on control charts – I try to do the same with all figures that I find.
