Statistical Process Control (SPC) allows for real-time process adjustments before product characteristics are out of specification. Understanding the charts, the rules and some theory can help operators make better decisions during production, and thus reduce waste. Module I focuses on the average-range chart, importance of accurate data, and interpreting for control conditions. Module II continues with more theory, more charts and understanding capability indices.
Calculate average and range and accurately plot and read graphs
Distinguish spec limits from control limits
Describe common rules for in-control
Identify potential causes for chart conditions shown
Describe normal distribution and capability
