Statistical process control (SPC) is an analytical technique that plots data over time. It helps us understand variation and in so doing guides us to take the most appropriate action.

This tool will enable you to:

• record your data on a daily, weekly or monthly basis and plot it on an SPC chart automatically
• indicate when a process may have changed by automatically applying SPC rules to the data
• annotate your chart and when appropriate apply step changes to your mean and process limits.
