Fast tips to Statistical Process Control
While writing PMA many interesting points came to my mind and contribute to better knowledge of Six Sigma. These are the following thoughts that can be applied to almost any process:
- Identify measures that you daily face with. For example, in fashion retailing company that I was studying, managers were routinely collecting the data, but didn’t know what would happen next – how they would measure the process with that data. Thus, before collecting, identify propose and try to foresee what kind of data you may need for measurement.
- Adapt data. It is vital to filter any noise factors from the process. If you don’t, the process behavior chart will be bias and useless and will show you wrong result.
- Put the data into the context. The process behavior charts will help to consider information globally and see the whole picture of the process.
- After analyzing if the process is under control the voice of the process should be compared with the voice of the customer to find out if the process suits to customers’ expectations.
This is just a small part of SPC – quick tips. I still have lots of questions. But, these basics can be applied not only in terms of Six Sigma project or SPC, they are the rules for business to stay “healthy” and “wealthy” all the time.
