Ans: The different kinds of variation are — mean, median, range and mode.
Ans: Six Sigma implementation team has five key players:
Ans: The DMAIC methodology, instead of the DMADV methodology, should be used when a product or process is in existence at your company but is not meeting customer specification or is not performing adequately.
The DMADV methodology, instead of the DMAIC methodology, should be used when:
Ans: There are a number of quality management tools. Some of them are cost-benefit analysis, CTQ Tree, SIPOC analysis, COPIS analysis, and Taguchi methods. (Name at least five)
Ans: Definition of Cost of Poor Quality (COPQ): Those costs that are generated as a result of producing defective material.
Ans: DPMO is abbreviated as Defects Per Million Opportunities and
DPPM is abrivated as Defective Parts Per Million.
Ans: The 80:20 ratio of cause-to-effect became known as the Pareto Principle.
Ans: It is a visualization tool for categorizing the potential causes of a problem in order to identify its root causes. Pareto Principle. Pareto principle is a prediction that 80% of effects come from 20% of causes.

Ans: Load testing is a kind of Performance Testing which determines process of putting demand on a software system or computing device and measuring its process
Ans: This should reflect the skills that you have regarding the statistical tools with respect to Six Sigma. Be honest while answering the question.
Ans: Cpk is process capability index, which measures how close a process is running to its specification limits, relative to the natural variability of the process and Ppk is process performance index, which verifies if the sample that have been generated from the process is capable of meeting Customer CTQs (requirements).

Ans: Standard deviation indicates the degree of variation in a set of measurements or a process by measuring the average spread of data around the mean.
Ans: Process sigma is a measure of the variation in a process relative to customer requirements.
Ans: The 1.5 sigma shift adjustment takes into account what happens to every process over many cycles of manufacturing.
Ans: Regression Analysis is a technique used to define relationship between an output variable and a set of input variables.
There are several types of regression like Simple Linear Regression, Multiple Linear Regression, Curvilinear Regression, Logit Regression and Probit Regression etc., which caters to a variety of requirements based on the type of underlying data.
Ans: A defect is any non-conformance of the unit of product with the specified requirements. A defective is a unit of product which contains one or more defects.
Ans: Process Report is used with continuous data that follow a bell curve distribution, while Product Report applies to discrete data and therefore can be used for all type of distributions.
Ans: FMEA is a qualitative and systematic tool, usually created within a spreadsheet, to help practitioners anticipate what might go wrong with a product or process.
Ans: They are a set of two charts, which is the most commonly used statistical process control procedure used to monitor process behavior and outcome over time.
Ans: A flowchart is a diagram displaying the sequential steps of an event, process, or workflow. Brainstorming is a technique used to quickly generate creative or original ideas on or about a process, problem, product,or service.
Ans: In 1986 Six Sigma was developed by Motorola.
Ans: Six sigma’s purpose is to identify the causes of defects and errors and then remove them in the manufacturing process.
Ans: Six Sigma has a greek symbol which is” sigma”. It is the standard deviation utilized to measure the variation in the process.
Ans: They are DMAIC and DMADV
Ans: The letters in the abbreviation DMADV stand for define, measure, analyze, design, verify," the steps in the ordered process.
Ans: DMADV is an abbreviation for define,measure,analyze,develop,verify
