  21. Attribute Control Chart ASQ Presentation 4/15/08 Andy Lauber alauber@att.net

  22. How to implement and use SPC • Evaluate current process • Determine if process is in control • Common cause variation • Special cause variation • Involve people • Only chart what you can handle • Immediate action to out of control conditions ASQ Presentation 4/15/08 Andy Lauber alauber@att.net
