1.) What is the process capability ratio (Cp)?

• Compares acceptable tolerances (normally set by engineers) with the process actual variation so you can assess the process ability to achieve required quality levels
• Process used to fill orders for quantities less than a full case requiring orders to be picked from a case or similar container
• Reduces the process variation to achieve near-flawless quality
• Measures the variation in output and sets control limits based on observations of variations arising from common causes
• None of the above

2.) Which of the following indicate that a process is out of control?

• A single point plots outside the control limits
• Two out of the three successive points are on the same side of the centerline and farther and 2 from it
• A run of eight in a row are on the same side of the centerline
• Any consistent or persistent pattern
• All of the above

3.) A control chart that is constructed using a range is called a/an

• x chart
• R-chart
• p-chart
• s-chart
• None of the above

4.) Which of the following are potential sources of variation in the Ishikawa cause-and-effect diagram?

• a. Materials
• b. Measurements
• c. Environment
• d. Prices
• e. All of the above
• f. Only a, b, and c
