Lean Six Sigma Black Belt Sample Paper: Improve 1. Which of the following statements is True for a Resolution III design: The main effects are aliased with second order interaction effects The second order interaction effects are aliased with the third order interaction effects All effects can be estimated without any confounding or aliasing There are no main effects but only third order interaction effects2. In developing a statistically significant model during the analysis phase of Design, the Pareto of Standardized Effects showed in the figure below, which order will you remove the statistically insignificant terms in: AC, AB, ABC ABC, AB, AC ABC, AC, AB AB, AC, ABC3. 5 meat softeners are to be tested in a cooking experiment to be completed in a short time. 5 different heat settings and 5 different chefs are considered as noise factors. Which of the following is the most effective tool to be used in this case? Randomized Design Non Randomized Design Randomized Design with Center Point Latin Square Design4. Which of the following is not a deliverable of Improve Phase? List the various possible solutions Evaluate the Alternative Solutions Handover the revised documents to Process Owner Optimize the alternative solutions5. A factor 5 design with 8 runs is a Resolution IV design Resolution III design Resolution V design Resolution VI design6. What is the number of replications required to run a full factorial design with a power of 90%, if there are 3 factors and 2 levels. Assume the difference to be detected is 0.5 and standard deviation is 0.25 1 2 3 47. The figure below shows the interaction plot indicating the impact of Speed of Service and Quality on the outcome “Satisfaction”. What can be said about the interaction between the two inputs: a) There is interaction between the two inputs Speed of Service and Quality b) There is no interaction between the two variables c) There is interaction between input Speed of Service and Outcome Satisfaction d) There is interaction between input Speed of Service and Outcome Satisfaction8. What are the advantages of running a pilot: It can help test the solution You don’t need to do full scale implementation if you run a pilot You can do the handover to the process owner if the pilot is successful None of the above9. Which of the following tools help compare an existing solution with alternative solutions: Pugh Matrix Multi Voting Nominal Group Technique FMEA10. Which of the following tools offers an advantage of a person pointing out negatives of a solution not getting criticized: Creative Thinking with Six De Bono Hats Benchmarking Brainstorming Creative Thinking by probing11. Which of the following tools CANNOT be used to validate if the pilot was successful Hypothesis Testing FMEA Box Plot Ishikawa12. Which of the following tools uses expert opinion via carefully designed questionnaires and does not require face to face interaction: Nominal Group Technique Delphi Technique Multi Voting Pugh Matrix13. If there are 3 factors and 2 levels to each factor, the total number of experiments needed are: 6 8 27 1814. Looking at the figure, select the correct statement: It is a resolution V design with 5 factors and 2 levels It is a resolution V design with no randomization It is a design with 2 blocks and a center point for one of the factors It is a resolution V design with replication of runs
