front 1 After the successful completion and implementation of the first four phases of DMAIC, the control phase should be completed by which of the following?
| back 1 d |
front 2 Process A consists of several machines that combine their output into a common stream. Once combined, it is impossible to trace single pieces to specific machines. Process B receives the mixed pieces. A corrective action requires finding the root cause of a defect found in some of these pieces. A team assigned to this problem is thinking of using SQC to detect the source of the problem. Where should SQC be implemented?
| back 2 b |
front 3 Which of the following would be a device associated with the visual factory?
| back 3 b |
front 4 Advantages of control charts include:
| back 4 a |
front 5 Control limits are set at the 3 sigma level because:
| back 5 b |
front 6 A process is checked by inspection of random samples of four shafts after a polishing operation, and X-bar and R charts are maintained. A person making a spot check picks out two shafts, measures them accurately, and plots the average value on the X-bar chart. The point falls just outside the control limits. The department foreman is advised to stop the process. This decision indicates that:
| back 6 d |
front 7 The factor D_4 in X-bar and R control charts is used to:
| back 7 a |
front 8 What is the importance of the reaction plan in a control plan?
| back 8 a |
front 9 The control chart that is most sensitive to variations in a measurement is:
| back 9 d |
front 10 After the successful implementation of an "improve" stage, a DMAIC team is considering control charts to monitor the new gains for a process. Which approach would provide the best results?
| back 10 b |
front 11 Which control chart pattern best represents an in control process?
| back 11 c |
front 12 An R chart is generally used to:
| back 12 c |
front 13 The single most important factor in establishing an effective company training effort is:
| back 13 a |
