  2. While Mohammed's answer is right, it does not provide examples as was asked in the second part of the question. Hence, there are no winners to this question.
  3. Q 318. Explain Control and Impact Matrix and its usage in DMAIC project. Do you think this matrix should be used for evaluating root causes (Analyze Phase) or is it better suited for assessing solution alternatives (Improve Phase)?

  4. In-line production inspection is measuring the product in the production line and offline inspection is the measurement of the product is carried out by removing from the production line . This can either be retuned to the line, discarded or kept as a rest sample .

  6. Training should be start with introduction of trainer as well as trainee then come to the main topic Then one by one clear all the contents the communication should be clear to understand the trainee
  7. Q 317. Product inspection can be done in two ways - inline and offline. What are the differences between the two? Provide examples of usage of both.

  8. Both are random sampling. Sratified allows you to pick basis a specific criterion eg pick 10 girls ans 10 boys randomly from the total group. Cluster may have eg several districts having large population are clusters and lets say out of 50 districts you chose 5 randomly out of that 50 is clustered sampling
  9. It is important to have an unbiased sample concerning the population when conducting surveys so that the results and predictions made are more accurate. This may not be the case of random sampling as here the samples are always biased as it does not represent the population accurately. Hence, Stratified sampling and Cluster Sampling are preferred to overcome the bias and efficiency issues of simple random sampling. Difference between Stratified and Cluster Sampling:

  11. Best answer to this question has been provided by Glory Gerald for explaining WBS in detail and supporting the answers with many examples. Also review the answer provided by Mr Venugopal R, Benchmark Six Sigma's in-house expert.
  12. Q 316. The population is divided into smaller parts in both cluster and stratified sampling. However, both are different. How is Cluster sampling different from Stratified sampling?

  13. Work Breakdown Structure (WBS) is a technique or a tool that is used to breakdown complex work to smaller tasks , thus making the overall work more manageable and approachable. It is a very popular project management tool that helps in dividing the the project deliverables into sub deliverables and work packages that will define work, duration, costs involved to carry out each of the tasks. Steps to create Work Breakdown Structure for effective project scope management: Identify Team : Identify the team who will work on the project deliverables that may be divided further
  14. Heirarchical decomposition of the work required to produce deliverables as described in the scope of project. Work NOT mentioned is considered OUT OF SCOPE Example: Recipe is WBS for each dishes on the menu card. Menu card should only mention dishes that can be served.
  15. Benchmark Six Sigma Expert View by Venugopal R Work Breakdown Structure (WBS) is defined as “the Hierarchical Decomposition of total scope of work to be carried out by a project team to accomplish the project objectives and create the required deliverables” – PMBOK The concept of WBS has emerged from the PERT (Program Evaluation & Review Technique) by US Department of Défense. In 1987, the Project Management Institute (PMI) documented the WBS method for application on non-defense industries. WBS is an important tool as part of the project scope management. The

  17. Premkumar T has provided a holistic answer on A3 Problem Solving methodology and hence he has been selected as the winner for this question.
  18. A3 which is commonly referred in terms of paper size “11.7*16.5” inches. A3 is also an important problem solving “lean management” tool introduced by Toyota. A3 Report is a single page document, which highlights the problem and solution for whole process. There are 7 Major elements of A3 Report are: 1) Background – highlighting the problems at hand 2) Current Situation – elaborates and highlights current baseline performance. Also highlight “As-is situation” 3) Target Setting – Establishing and validating target the improvement opportunity
  19. A3 Problem Solving: It’s a practice started in Toyota later adapted in lean methodology. There is a huge difference between the movies before the 1930 and after, yes your guess is rights its about the sound. The same logic applies when we discuss about the problem in shop floor with or without a Print / Soft copy document which describes the Problem status. To bridge the gap, A3 Problem solving tool in place. A Typical A3 Problem solving tool standard, looks as above. (The Yellow text box comments indicates “HOW TO”)
  20. Introduction: A3 Problem solving technique is used for continuous improvement efforts in many organizations. It is a lean approach that was originally created by Toyota with the objective of in depth problem solving and help people and teams to work together. The term "A3" is derived from European paper size that is measured as 11 inch by 17 inch. It was used by Toyota to solve a problem, to report on project status and to make a process change proposal. The A3 Problem solving technique is based on Deming's Plan, Do, Check and Act (PDCA) method, and the steps involved are explaine
  21. Glory has provided the best answer to this question by explaining both the terms and by providing multiple examples for both. All other answers are worth a read for the brilliant examples quoted. Also review the answer provided by Mr Venugopal R, Benchmark Six Sigma's in-house expert.
  22. Q 314. A3, apart from being a standard paper size, is also a powerful problem solving technique. What is A3 Problem Solving and how does it help build a culture of continuous improvement?

  23. Cost avoidance measures are action taken to avoid having to incur costs in the future. The benefits from cost avoidance can not be shown on financial statements and cannot be reflected in the budget. They are more difficult to estimate. EXAMPLE In a manufacturing setup, management may decide to reduce spending on preventive maintenance activities because the current frequency does not appear justifiable. Some parts may have been scheduled to be changed 6 times a year, perhaps from manufacturers’ recommendations or as outcomes from previous improvement projects. This high frequency ma
  24. Cost avoidance includes steps which are taken which will help reducing the cost that will be incurred by an organization in future. Cost avoidance aims at having a minimal increase in cost but reducing future cost. Examples of Cost Avoidance :- 1. Making changes in the machinery which might increase the cost initially but will bring down cost of production in future 2. Setting up a new Quality department in a leather industry which can help in reducing the losses incurred due to the cargo being rejected due to Quality reasons. 3.Investment by a
  25. Benchmark Six Sigma Expert View by Venugopal R Lean Six Sigma and Business Excellence professionals often come across improvement projects that are important but sometimes difficult to justify the gains to get a CFO approval. A “Cost avoidance” related projects is perhaps one such situation. I recall a situation where the customer has a penalty clause if the Quality level of our output falls below 98%. For many years, we have been managing very well, barring some occasional blips and maintained Quality levels high enough to avoid the penalties. One fine day, the customer revises the SLA a
  26. Cost Reduction Vs Cost Avoidance Examples giving comparison of Cost Reduction & Cost Avoidance Other Examples of Cost Reduction & Cost Avoidance Cost Reduction: • Reduction of Overtime in a company • Partnerships where a company can find a partner to invest in certain assets or services in order to reduce costs. • Location Strategy of a company – migration of work to a new location due to availability of cheap labor when compared to home location. Cost Avoidance: • Investing in new technology (one time investment)
  27. Businesses globally work on the principle of win work (top line) - do work (execution) - make money (bottom line). Businesses constantly endeavor to maximize top line and increase bottom line. Execution of work requires companies to incur costs. For a manufacturing company, it may be capital expenditure with operating costs. For construction businesses, costs relate to hiring equipment, skilled and unskilled workforce etc. For Asset operators, for exampl e.g. airport operators, costs will include money spent on operations including the upkeep/ maintenance/ security/ staff both
