Statistical process control (SPC), despite sounding esoteric, is a subject that every process owner and worker should – and can – understand, at least at a high level. Knowing whether a process is in control and stable is paramount to producing a product or service that meets customer needs.
In this hour-long Minitab training course that took place in Seattle, Eduardo Santiago covers many useful topics related to SPC, including:
- The difference between common-cause and special-cause variation (1:28)
- Rational subgroups and why they are necessary when collecting data (8:30)
- Two separate phases for running control charts (30:00)
- Determining when a process is in control and out of statistical process control (31:00)
- The eight tests for identifying special causes of variation (36:27)
- Stages of statistical process control (56:47)
