Voice of the Customer What do the letters in the Six Sigma acronym DMAIC stand for? Define, Measure, Analyze, Improve, Control To what does SIPOC refer? A process model Quality characteristics that fall under the heading of conforming or nonconforming. Attributes Quality characteristics that are measurable to any degree of subdivision. Continuous Variables Quality characteristics that are measurable, but are restricted to certain values. Discrete Variables If a measuring instrument is precise, but not accurate, it means that the measurements: Are grouped tightly together, but do not reflect the "true" reading The "Greatest Possible Error (gpe) is: Equal to 1/2 of the Precision Which of the following answers has the correct number of significant figures (assuming 12 is not a counting number)? 25.369 / 12.0 = 2.11 Which of the following answers has the correct number of significant figures (assuming 12 is not a counting number)? 25.369 + 12.00 = 37.37 What is the mode of the following series of numbers: 1, 1, 2, 2, 2, 3, 4, 5, 5 2 Data that have a skewness value of -0.5 and a leptokurtuc distribution have a: long tail to the left and a more peaked than normal distribution The best method to assess if sample data fit a normal distribution, assuming a minimum sample size of 125 is available, is: A chi square goodness of fit test In general, variation due to inspection should be less than the other four sources of variation. Approximately how much less? 1/10 What terms did Dr. W. Edwards Deming use when referring to "chance" and "assignable" causes of variation? "common" and "special" The text suggests that control limits are usually established at plus/minus how many standard deviations from the central line? 3 The frequency with which an operator inspects a product at a particular work center is determined by: the quality of the product Variables control charts provide information. Which of the following is NOT a potential objective of such control charts? To determine an appropriate acceptance sampling plan A rational subgroup is one in which: the variation within the group is due only to chance causes Regardless of the scheme used to obtain rational subgroups, the lots from which the subgroups are chosen must be: homogeneous When the subgroup size exceeds a certain number (rule-of-thumb), the "s" chart should be used instead of the "R" chart for control of dispersion. What is that number? 10 What is the minimum number of subgroups recommended by the text to provide a sufficient amount of data for the accurate computation of the central line and control limits? 25 What is the definition of a Type I error? A chance cause is present and the plotted point is outside the control limits The plotted points for an X-bar group control chart are: the highest averages AND the lowest averages, that is both (a) and (b) above When there are eight streams plotted on a group control chart, how many times in succession would the same stream have to give the highest or lowest value to be considered out of control? 4 Statistical Process Control of batches has two forms. What are they? between batch and within batch The standard deviation used in a specification chart is calculated from: a formula based on an assumed Cp and the tolerance The center line on a deviation chart for individuals is: always zero The upper control limit of a W chart is: D4 An MW chart plots the moving range of the: "Z" value Precontrol lines are located __________ between the nominal value and the outside limits of the tolerance. 1/2 of the way A PTPCC chart is essentially a combination of: a Z chart and precontrol In gage control, reproducibility is due to: inspector variation
