PART 2: Process Capability
Bobcat Manufacturing is also concerned if the process is capable of producing the part at the customer requested three-sigma quality level. The potential customer’s specifications for the part are 8.0 ± 3.0 millimeters. Use the “Process Capability” solver in OM Explorer [Note: The table below is the same data as Part 1; combined and formatted for process capability solver.]
(C) If management wanted to improve the current process, should they first focus on reducing variability or centering the process?
BONUS QUESTION (optional): Notice all of the samples fall within the customer’s specifications of 8.0 ± 3.0. How does this make sense considering your answer to Part 2 (C)?
