Control Chart Analysis Reaction

Systematic Variables

3.ACT

Decide on appropriate action and implement it.

Identify on the control chart

The cause of the problem

The action taken

As far as possible,eliminate the possibility of the special cause happening again.

4. CONTINUE MONITORING

Plotting should continue against the existing limits

The effects of the process intervention should become visible. If not, it should be investigated.

Where control chart analysis highlights an improvement in performance, the effect should be researched in order that:

Its operation can become integral to the process

Its application can be applied to other processes where appropriate

Control limits should be recalculated when out of control periods for which special causes have been found have been eliminated from the process.

The control limits are recalculated excluding the data plotted for the out of control period. A suitable sample size is also necessary.

On completion of the recalculation, you will need to check that all plots lie within the new limits
