Understanding Statistical Process Control (SPC)

Having reviewed feedback from visitors to our website we have found that we get a lot of requests for information on Statistical Process Control (SPC).

We will be launching a series of articles during the next couple of weeks that aim to provide a foundation understanding of SPC and it's application, this will hopefully help you make an informed choice about whether SPC is the correct tool for you!

Our intention is to provide a solid foundation for understanding SPC, the terminology, metrics and uses of SPC along with  useful resources which can be downloaded and customised to suit your specific requirements, the first of which (X-bar and R chart) is available below.

My job takes me into all types of business, and I often find SPC charts being displayed, but when I ask the client they are either not correctly used or not correctly interpreted.

The articles will be broken down into small bite size offerings that can be used for future reference. We will also be making available the relevant resources, including an SPC chart, calculation sheets and a table of constants along with some recommended further reading.

The information will be split into the following articles for ease:

• The basic statistics behind SPC (for variable data)
• Probability and SPC
• Collecting and plotting data (using the X-bar and R chart)
• Interpreting the chart, including the seven points rule
• Understanding capability
• Applying SPC

The article structure will be on our website so if there is something that interests you, keep an eye out!  You can sign up to receive notifications to our Blogs here and our Facebook page can be found here.

If there are any SPC questions we haven't answered, or for any queries or feedback, let us know either via the contact form here or by emailing julie.camp@resultsresults.co.uk
