Lean Six Sigma Black Belt Sample Paper: Control 1. Door Ajar warning in a car and wipers of a car switching on when it rains are examples of which type of Mistake Proofing techniques respectively Warning, Shutdown Warning, Control Control, Shutdown Control, Warning2. Which is the most preferred method of ensuring process control: Visual Control Statistical Process Control Flowcharts Poka-Yoke3. Which of the following are a part of the project hand off meeting to the Process Owner: Sign off by process owner Control Plan Sharing best practices with the process owner All of the above4. Control charts show: Only random variation Only non-random variation Random and non-random variation Different types of variation depending on the type of process5. A stable process has only common cause variation. A control chart depicts non-random variation via: Points lying outside the control limits Points lying outside the specification limits Sudden shifts in averages Wide swings I, II I, II, II I, III, IV I, III6. 5 phones are checked from every production lot and are categorized as defective or non-defective. Which control chart will you use to analyse that the process is in control NP chart P chart C Chart U Chart7. Select the advantage of using X Bar S chart over X Bar R chart: Minitab can calculate standard deviation in X Bar S chart whereas the range for X Bar R has to be calculated manually It takes all data points into account for calculations It has lesser sensitivity to variation, hence is a more robust tool There is no real advantage of one over the other8. Choose the INCORRECT statement: Continuous Data follows Normal Distribution Defective data follows Poisson Distribution Defect data follows Poisson Distribution Defective Data follows Binomial Distribution9. A Team Leader performs random spot checks on the order forms completed by his team members and counts the number of defects per form. He completes as many checks every day as his schedule allows. Which control chart can be used to assess whether the process is in control: IMR Chart C Chart NP Chart U Chart10. One of the way of indicating the presence of a special cause is on a control chart is if 2 out of ____ points are more than 2 standard deviations away from the center line (on the same side) 3 5 8 1511. Which of the following activity is NOT done post plotting a control chart: Identify the assignable causes Eliminate the causes Take actions to prevent the assignable causes in future Perform Measurement System Analysis12. Which if the following indicate the purpose of putting a control plan in place: Determine the plan to maintain the Xs Ensure that the process is well documented Outline corrective actions Ensure communication and training to the people who run the process I, II I, II, II I, II, III, IV I, III, IV13. Documenting of solutions, benefits and lessons learnt serves what purpose: The solution can be easily replicated in similar areas while avoiding any pitfalls Management can win awards basis the documentation It is required for the final sign off from process owner It eliminates the need for any audits14. Communication of project recommendations must try to include the following form/s of delivery: Auditory mode (learning through listening) Visual mode (learning by seeing and associating with images) Kinaesthetic mode (learning by doing) All of the above15. In control phase, to ensure sustenance of improved performance, ongoing evaluation includes Continuing to meet with the project team after the handover to process owner is complete Monitoring process CTQ periodically Starting a new DMAIC project in the subsequent year Eliminating audit and inspection16. At the end of the project, financials are validated by ______ and the process is handed over to the __________ Financial Analyst, Sponsor Financial Analyst, Process Owner Project Leader, CEO Champion, Process Owner17. The financial benefits computed at the end of the project must Be validated by an unbiased financial expert Indicate projected hard benefits which will be monitored for at least period of 1 year Either 'Be validated by an unbiased financial expert ' or 'Indicate projected hard benefits which will be monitored for at least period of 1 year ' Both 'Be validated by an unbiased financial expert ' and 'Indicate projected hard benefits which will be monitored for at least period of 1 year '18. Which of the following is NOT a part of the Control phase? Creating a Control Plan Handoff meeting with the process owner Optimizing the Solution Identifying Best Practices and Replication opportunities19. On a factory floor, display of total number of units produced vs the daily target is an example of: Visual Control Poka Yoke Kaizan Kanban20. Which of the following is NOT a tool that can be used to keep the process in control: Process Documentation Mistake Proofing Pareto Statistical Process Control21. The resource whose role description indicates that they are responsible for taking over a project after project completion is: Master Black Belt Deployment Champion Process Owner Project Lead22. Which of the following is a test for special cause in c chart: 15 points in a row on the same side of the center line 9 points in a row, all increasing or decreasing 14 points in a row alternating up and down 1 point more than 2 standard deviations from the center line
