Graph Out Loud
A graphical method for Categorical X and Continuous Y. This graph can be stratified into groups for comparison.
What is a Histogram?
A hypothesis that is a statement of no effect or no difference. It is abbreviated as Ho.
What is the Null Hypothesis?
Any gap between actual current state performance and an existing/new standard or target condition. A matter or situation regarded as unwelcome, harmful, and needing to be dealt with or overcome.
What is a problem?
An idea generating technique that helps the team question what is taken for granted, breaks the team out of traditional and logical thinking patterns, and generate bold new ideas.
What is Provocation and Movement?
The 2 components of variation.
What are Common Cause and Special Cause variation?
A plot type for Categorical X and Continuous Y, it include confidence intervals about the mean that are calculated based on the sample mean, population, sample size, and degree of confidence desired. Non-overlapping intervals indicate that a statistical test will determine the means are different with the state degree of confidence.
What is an interval plot?
A hypothesis about our population that we want strong evidence to be able to prove. Abbreviated as Ha.
What is the Alternate Hypothesis?
Prevents flow, and does not add value.
What is waste?
The DMAIC phase is where the solution is implemented.
What is the improve phase?
A control chart that is a simple running record of a process characteristic over time. It can show cycles, shift, drift, or special causes/outliers.
What is a Run Chart or Time Series Plot?
A graphical tool for Categorical X and Continuous Y. These plots show each data point, similar to scatterplots but with Discrete X's.
What is an Individual Value Plot?
A type of error that is rejecting the Null Hypothesis when it is, in fact, true.
What is a Type I error?
Each letter meaning in 6S.
What is Sort, Set In Order, Shine, Standardize, Sustain, Safety?
A solution selection tool that groups similar ideas together to help prioritize potential solutions.
What is the affinity diagram?
A control chart that shows the individual data points over time on the top chart, and the range from data point to data point on the bottom chart.
What is an individual moving range chart? I-MR chart.
A graphical method used with Continuous X & Continuous Y, this plot type is for paired combinations of X & Y. Continuous X's and Y's can be in either numeric or date-time format in Minitab.
What is a scatterplot?
A type of error that is accepting the null hypothesis when it is, in fact, false.
What is a Type II error?
5 kinds of human errors.
1.Forgetfulness 2.Errors due to misunderstanding 3.Errors in identification 4.Errors made by amateurs 5.Willful errors 6.Inadvertent errors 7.Errors due to slowness 8.Errors due to lack of standards/supervision 9.Surprise errors 10.Intentional errors
Each letter's meaning in the SCAMPER idea generating technique acronym.
What is Substitute, Combine, Adapt, Modify/Mirror/Distort, Put to other purposes/uses, Eliminate, Rearrange/Reverse?
A document that is used to tie in all of the control actions within the scope of the project
What is a control plan?
A graphical tool for Categorical X's and Continuous Y. This plot shows 2 X's on the same plot, and show the non-additive effects of 2 input factors. On this type of plot, parallel lines would indicate no interaction effect.
What is an Interaction Plot?
A hypothesis test used to compare the variances (spreads) of two populations. The null and alternate hypotheses for this test are: Ho: Var(1) = Var(2), Ha: Var(1) ≠ Var(2).
What is the 2-Variance test or 2-Sample Variance Test?
A level of quality or attainment. An idea or thing used as a measure, norm, or model in comparative evaluations.
What is a standard?
A brainstorming technique that includes generating and sharing ideas in writing, differing from traditional brainstorming where ideas are shared verbally. The silent nature of the process increases the likelihood that everyone will participate and build on each other’s ideas.
What is Brain Writing 6-3-5?
A control chart that uses rational subgrouping to group data together based on common shared conditions.
What is an Xbar and R Chart?
