Discuss one (1) project where you used a problem-solving approach to address what turned out to be common-cause variation, or where you used a process improvement approach to deal with a special cause.

If you do not have a personal experience that echoes either of these situations, you may use Internet to search for a case that reflects either of these situations.

Examples:

• one's personal investment strategy since 2008
• reducing waiting times at the local hospital or emergency room
• reducing difficulties trying to connect to a Wi-Fi Internet provider

Answer the following questions in the space provided below:

• Describe the experience in the project.
• What were the solutions used to address the problem?
• Was the case you described a special-cause or common-cause?
• Do you feel the solution or approach used appropriate for the cause?
• What would you do if you could do it again?
