Unit 5 Discussion - Control Charts and Presidential Polls

Provide examples of some practical applications of Statistical Process Control (SPC) and control charts that you could use to monitor your health, the performance of your car, or the performance of some other system you use in your personal life. How about in your work life? How would you use that information? Discuss why it is important for managers (or anyone else) to know whether a variation in system performance comes from common cause variation or special cause variation.
