- What does the phrase “in control” mean with respect to
processes?
- An in-control process is one in which the output falls within the specification limits.
- An in-control process is statistically stable; it is free of assignable or non-random variation
- An in-control process is one in which the process width (i.e., 6σ) is substantially wider than the specification width (i.e., the upper specification limit minus the lower specification limit)
- None of these is correct
Homework Answers
The correct option is B. An in-control process is statistically stable; it is free of assignable or non-random variation as in control processes are under control limits and are stable.

Samples of n = 6 items are taken from a manufacturing process at regular intervals. A normally distributed quality characteristic is measured and ?̅ and S values are calculated for each sample. After 50 subgroups have been analyzed, we have : ∑ ?? ̅50 ?=1 = 1000 and ∑ ?? 50 ?=1 = 75 (a) Compute control limits for the ?̅ and S control charts. (b) Assume that all points on both charts plot within the control limits. What are...

A certain process is under statistical control and has a mean value of 130 and a standard deviation of 8. The specifications for the process are: a. USL (upper specification limit) = 150 b. LSL(lower specification limit) =100 a. Calculate the cp and cpk b. Which of these indices is a better measure of process capability and why? c. Assuminng a normal distribution what percentage of output is expected to fall ourside the specification. Why is it important to know...

1 - Almost all processes, regardless on whether they are goods or services, exhibit some type of variation in their output. For example, a box of cereal may say that it contains 16 ounces, but in reality, it may be a little bit more, or a little bit less. The machine pouring the cereal into the box may not be adjusted properly, and it may only put 15.8 ounces in each box, on the average. This would be considered an...

The Operations manager at a large widget factory is complaining that since the company has changed to a cheaper supplier for one of the raw materials used for widgets, the quality of their widget has changed. In fact, he has one of the final widgets that has a strength testing below their spec.
