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 80+ 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.) Observations (millimeters) 91 8 7.6 82 9.1 9 8.2 7.9 82 10 8.1 92 10.1 &2 9 7.5 8.9 7.8 93 9.1 9.3 101 88 88 10.8 87 10 (A) What is the process capability ratio (C.)? (B) What is the process capability index (Cx)? (C) is the process capable of producing three sigma quality? (D) of management wanted to improve the current process, should they first focus on reducing variability or centering the process
