According to the customer’s specification given to the manufacturer, the length of a shoe should not
deviate from the correct size by more than 1 mm. In the manufacturing process, the standard deviation
of this length is 0.32 mm and the mean is equal to the correct size. Find the capability ratio of this
process for three standard deviations. Is this process capable?
Correct!
1.04; yes
0.52; yes
1.04; no
0.52; no
The capability ratio is calculated as the upper specification limit (USL) - the lower specification limit (LSL)
divided by 6 (sigma). The deviation from the correct size (mean) is 1 mm on each side. Cp = [(X-bar +1)
— (X-bar -1)]/6sigma = 2/(6 x 0.32) = 1.04 > 1, which indicates that the process is capable.
Question 2
10/ 10 pts
The four main categories associated with a cause-and-effect diagram are:
Correct!
Manpower, machines, materials, and methods.
Person, machines, technology, and quality.
Materials, machines, methods, and money.
Person, place, methods, and materials.
None of these answers.
The cause-and-effect diagram, also known as an Ishikawa or fishbone diagram, is a way to identify
potential root causes for a quality problem. The four general categories associated with the diagram are
manpower, machines, methods, and materials. Through brainstorming, potential root causes are
identified for each area.
