  1. The chosen best answer is that of R Rajesh, because of the structure and detail. Each one of the answers, however, outlines some unique challenges that keeps practicing GBs away from Hypothesis Testing. Read through to get a well rounded understanding before you devise a plan on how to overcome these obstacles. If availability of software is one of them, use our calculators at https://www.benchmarksixsigma.com/calculators/ Our expert view is provided by Venugopal R
  2. The chosen best answer is that of Sandra as she has outlined how FMEA can be used in each phase of a DMAIC project. In addition, read answers from Steve C, Kev N to complete a rounded view of how FMEA can be used in all phases of DMAIC. Charlie's answer highlights the different FMEAs that can be used in a project and Sujata's answer clearly outlines what FMEA is and why it should be done.
  3. Q. 160 Hypothesis Testing - Business Success for any company depends on Continuous Improvement(CI) . CI requires creating hypothesis and testing them frequently. Most organizations create and test hypothesis (do trials for new ideas or carry on small experiments). For some reason, most professionals do not carry out statistical testing of hypothesis on sample data and tend to rely on gut feeling. It is seen that most Green Belt professionals do not use it while they have been trained on it. What are the key reasons for lack of use of this powerful family of statistical tests?

  4. There are multiple high-quality responses to this question that have indicated deep understanding, experience and maturity in Root Cause Analysis. The chosen best answer is that of Sujata Dhawase - Three perspectives for root causes and a clear example explaining the perspectives. For readers, there is a wealth of knowledge on root cause in many responses, some of the notable ones are mentioned below. - "Interaction between causes" by Steve C - "Contributing vs. Root Cause" by Steve C - "Minimum and sufficient causes that eliminate the problem" view by Kevin - "Economic Elimination" view by Kevin - Crisp definition by Stephen J - Detailed definition by Leanne - "Multiple causal chains" view by Paul - "Scope of control" view by Chris- - "Influential factors" approach by R Rajesh - "Controlled Experiments" approach by Ransingh - "CNX Classification" by Prashanth Datta - "Primary root cause" concept by Chitra - "Actionability requirement" by Parsa - "Contributing cause" by Girish Vasan - "Practical Significance" view by Padmanabhan
  5. The chosen best answer is that of Sreyash. Do read through each of the answers as every answer has a piece of information to offer. For Benchmark Expert view, please read Venugopal's answer.
  6. You want output Y to improve and are looking for X that influences Y. Share examples when the outcome of a hypothesis test indicates statistical significance with respect to impact of X on Y but does not warrant a change in X
  7. The most common use of Attribute Agreement Analysis (AAA) is in evaluation of agreements in quality checks. In what other situations can you use AAA to your benefit?
  8. Assuming that you have a data set that follows normal distribution, give examples of how you could use probability distribution to make predictions for the outcome of some business processes.
  9. Q. 156 Activity-based costing (ABC) is a way of accounting which identifies and assigns costs to overhead activities. These costs are in turn assigned to products. Cite examples where using such a way of accounting has clear advantages and cite examples where using this method creates complications.

  10. Please refer to the Benchmark Expert view to get a clear picture of usage of Central Limit Theorem.
  11. It is necessary to have secondary metrics when we drive Six Sigma projects so that we are not solving one problem and creating another. In other words, we wouldn't be solving problems but they would just be changing shape. There could be several examples where the project fails despite improvement in the primary metric. Let's see a few here - 1. Customer Satisfaction increases but handling time increases 2. Order to ship time decreases but wrong deliveries increase 3. Order processing time of a certain component decreases but field failures increase 4. First Call Resolution increases but Handle Time also increases 5. A hair color that starts lasting longer but more users report damaged hair 6. Oil paints that dry faster but the pigments fade away faster. Please read the expert view given by Venugopal.
  12. Q. 155 Explain the practical application of Central Limit Theorem while collecting and analyzing data. Provide a few practical examples to support your responses.
