What does ISO stand for? - correct answers International Standards Organization How is six sigma defined? - correct answers Customer focused, problem solving methodology with a handful of analytical tools. What is continuous improvement? - correct answers Execution of carefully selected projects. Take small steps forwards, never backwards. What is the purpose of six sigma? - correct answers Better serve customer needs and expectations for increasing value to the customers for repeated business. What is the six sigma approach? - correct answers Statistics as interpretation tools. Changes in culture of the organization. Deep commitment from the highest levels of management. Endlessly questioning the validity. Strategy, not a destination. For six sigma to be effective... - correct answers Must be: 1) processes in place 2) processes controlled statistically 3) processes must be improved (by reducing variation)

What does DMAIIC stand for? - correct answers Define, measure, analyze, improve, implement, control (standardize and validate) The categories of profound knowledge are what? - correct answers 1) Knowledge of systems 2) Knowledge of statistics 3) Knowledge of psychology 4) Knowledge of knowledge Knowledge of systems - correct answers Interdependent components working together for an aim. Management's responsibility Variation: - correct answers Voice of the system. Shows patterns (special and common). Knowledge of Psychology: - correct answers Intrinsic motivation! Knowledge of Knowledge: - correct answers Prediction to observation to either throwing out the model or keeping the illustrations. Special Cause Variation - correct answers One-time occurrences. Find special cause and address, most likely close to the process.

Common Cause Variation - correct answers More ongoing, chronic, and persistent. Take action on the system, management is responsible. Stable Processes - correct answers Predictable, statistical control, known process capability. Control - correct answers Predictability! Basic Theorem of Variation - correct answers If we always do what we've always done, we'll always get what we've always got. Corollary to the Basic Theorem of Variation - correct answers Einstein's Theory of Insanity. Histograms - correct answers Representation of data in a bar chart format, and to observe the shape of the data. Statistics (Central Location, etc) - correct answers Central Location: Mean, median, mode. Variability: Range, standard deviation. Shape. Measures of Central Location - correct answers x (bar) is sample average, mu is the population average.

When to use the Central Locations - correct answers Mean: symmetrical, Median or Mode: not symmetrical Range - correct answers Difference between smallest and largest values: R. Standard Deviation Significance - correct answers 1 StDev = 68%, 2 StDev = 95.5%, 3 StDev = 99.73% 3 Sigma - correct answers Within 3, represents the expected limits of common cause variation. 6 Sigma - correct answers Customer requirements are 6 standard deviations from the mean in either direction. Grand Average and Average Range - correct answers x (bar bar) and R (bar) When Describing Data... - correct answers Target (goal), shape (can be normal or not normal) Control Charts - correct answers Shows the amount of type of variation present in monitored process, using UCL, LCL, CL, USL, LSL, Nom.

Western Electric Rules - correct answers Single point out of the limit, adjustment, reduction in variability, 2 or 3 consecutive points near one control limit, run, cycle, trend. Process Capability - correct answers Process is deemed capable if operating at a 3 sigma level. Can only be measured if all special causes have been eliminated. Percent Non-Conforming - correct answers Proportion of population that would not meet the process specifications. "Tails" on the areas of the normal curve. Cp - correct answers Measures the potential capability. Shows the a process can become capable by centering then the initial efforts should concentrate on that. USL - LSL / 6sigma

Cpk - correct answers Measures the current process mean's proximity to either specification limit. Sigma Level / 3 DEFINE - correct answers Identifying the problem and setting the scope. SIPOC. Supplies, input, process, output, customers. MEASURE - correct answers Identify and verify quality characteristics. Estimate current capability. Process capability, measurement of systems analysis, cost of quality. ANALYZE - correct answers Makes sense out of the data that is collected during measure. All goes to cause and effect. IMPROVEMENT - correct answers Evaluated and planned in a logical fashion. IMPLEMENT - correct answers Implementing the fashion. Developed and managed. CONTROL - correct answers Steps are taken to make sure improvements are maintained.
