Control Charts are Smart Charts!

Control charts not only display your data, but they analyze it too.

Control charts calculate a center line and control limits. As your data is compared to the control limits, built-in rules pinpoint performance problems.

These points and trends are highlighted and should be investigated.

Since QI Macros can create control charts for you in seconds, there's no reason to settle for primitive line and run charts. Use the "advanced technology" of control charts and spend time analyzing your data, not just drawing charts.
