After the successful completion and implementation of the first four phases of DMAIC, the control phase should be completed by which of the following?

1. The black belt alone; the project has been successfully completed
2. The process owner alone; it is his/her responsibility to take the project from here
3. The process owner and black belt together
4. The complete team is the most desirable option

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?

1. At the beginning of Process B
2. At each machine in Process A
3. At the end of Process B
4. At the beginning of Process A

Which of the following would be a device associated with the visual factory?

1. Standard work
2. Andon board
3. Queue time
4. Work cell
