A team has been asked to reduce the cycle time for a process. The team decides to collect baseline data. It will do this by:

Calculate the main effect of factor A (i. e. A+ – A– ).

(Refer to the previous problem) The variance of the five replications for each run is calculated. Most of these variances are approximately equal but two are significantly lower than the others. The experimenters would be especially interested in those two runs if they want to optimize:

An experiment has seven factors with two levels each. The experiment has eight runs. This experimental design is called:

The operators of a manufacturing cell work out a more orderly arrangement for tool storage and establish a schedule to maintain cleanliness on a daily basis. These improvements are best described by which approach to problem solving?

The quality leader responsible for the term Total Quality Management (TQM):

SCENARIO

A Six Sigma team is measuring the moisture content of corn starch as it leaves the conveyer belt of a dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locations labeled A, B, C, and D across the end of the belt. See the diagram below.

After some more work on the dryer, additional data are collected which when plotted looks like this:

Which type of variation dominates?

The preferred method for determining statistically whether factor A or B is significant requires what additional information?

A machine tool vender wants to sell an injection molding machine. The current machine produces 3.2% defectives. A sample of 1100 from the vender’s machine has 2.9% defective. Do these numbers indicate that the proposed machine has a lower rate of defectives?

The word “champion” in the context of Six Sigma projects refers to:
