Six Sigma Green Belt : AIGPE

Six Sigma Green Belt : AIGPE Questions And Actual Answers Ascertaining critical root causes. What tools are used to reveal information? (Analyze: step 2) - Pareto chart Box plot Scatter plot Multi-voting Control Impact Matrix Define a SIPOC? (Macro As Is Process Map) - Supplier- whoever provides input to process Inputs - process or data that a process does something with Process - Activities you must perform to satisfy customer requirements Output - Product or data that results Customer - whoever receives the output of your process Define Statistics - Statistics is a way to get information from data Define the acronym CAP - Change Acceleration Process Describe Classic Yield - Number of good parts at the end of the process over total number of parts started with Describe cluster sampling - Cluster sampling is a method of sampling in which clusters are sampled every nth time. Describe continuous data - Data that can be measured on a scale and can be meaningfully subdivided into finer increments Describe discrete data - Counted (attributes) Can only be particular values (integers). There may potentially be an infinite number of those values, but each is distinct and there's no grey area in between. Can be numeric; number of apples, number of sports cars, but it can also be categorical -- like red or blue, or male or female, or good or bad -- like apples and oranges or oranges and apples but not continuous. Describe Effective Measures - They determine how well your process meets the requirements - the are qualitative measures. Describe Efficiency Measures - They determine how well resources are allocated to execute the process - these are quantitative measures. Describe First Pass Yield - Number of good parts at the end that made it through without rework over total number of parts started with Describe random sampling - Basic design consisting of selecting a group of "n" units in such a way that each sample of size "n" has the same chance of being selected. Example - picking names out of a hat. Describe Rolled Throughput Yield - First Pass Yield 1 * First Pass Yield 2 * ... * First Pass Yield n Describe Sigma Shift - The long-term deterioration of process performance Describe Stratified Random Sampling - Used to ensure adequate representation of subgroups by providing random samples within each sub-group * Process * - identify logical strata (sub-groups) for study sample - determine sample size needed - obtain list for each strata - using either simple random or systematic sampling select respondents Describe systematic sampling - The single element is chosen at regular intervals from an ordered list.
