SPC - Statistical Process Control

SPC is used in most if not all quality programs including six sigma and ISO.

For additional details on control limits and their usage, see our Statistical Process Control Overview page and X Bar and Range Control Charts.

The act of gathering data or a sample, sometimes using stratified sampling, and almost always using random samples, that then is analyzing to monitor processes, identify performance, and determine variability and/or capability typically using special control charts like X-Bar, R-Bar, and/or distribution or histogram charts and a variety or other statistical tools. Use WECO rules or similar with the X-Bar and R-Bar charts to monitor trending.

Date types used are attribute or discrete and variable, (real number), data types. Different types of sampling can use different data types and attribute data uses different control charts than variable data types.

For an example of a X Bar and R Bar charts see our ZeroRejects features page. It makes doing statistical process control charts easy. And at only $150.00, (USD), our software can get you going quickly.
