Explain why it is important to update the control charts as soon as new data become available.
Answer 1: It is important to update the control charts as soon as we have new data to see whether this resulting data is indicating that the process has changed and if action is required. Another reason is that some assignable causes can get into the system and make it work with lower efficiency. The system always has to be up to date and whenever we have new information, it should be updated into the control charts, this in the long run can prevent system breakdowns.
