Which of the following is/are a part of the project hand off meeting to the Process Owner?Sign off by process ownerControl PlanSharing best practices with the process ownerAll of the above4. Control charts show ____________________Only random variationOnly non-random variationRandom and non-random variationDifferent 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 which of the following?I. Points lying outside the control limitsII. Points lying outside the specification limitsIII. Sudden shifts in averagesIV. Wide swingsI, III, II, IIII, III, IVI, III6. Five phones are checked from every production lot and are categorized as defective or non-defective. Which control chart will you use to analyze if the process is in control?NP chartP chartC ChartU Chart7. What is 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 manuallyIt takes all data points into account for calculationsIt has lesser sensitivity to variation, hence is a more robust toolThere is no real advantage of one over the other8. Which of the following statement is INCORRECT?Continuous Data usually follows Normal DistributionDefective data usually follows Poisson DistributionDefect data usually follows Poisson DistributionDefective Data usually 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 if the process is in control?IMR ChartC ChartNP ChartU Chart10. One of the ways of indicating the presence of a special cause on a control chart is - 2 out of ____ points are more than 2 standard deviations away from the center line (on the same side)3581511. Which of the following activity is NOT done post plotting a control chart?Identify the assignable causesEliminate the causesTake actions to prevent the assignable causes in futurePerform Measurement System Analysis12. Which of the following indicates the purpose of creating a Control Plan?I. Determine the plan to maintain the XsII. Ensure that the process is well documentedIII. Outline corrective actionsIV. Ensure communication and training to the people who run the processI, III, II, IIII, II, III, IVI, III, IV13. Which of the following purpose is served by documenting the solutions, benefits and lessons learnt?The solution can be easily replicated in similar areas while avoiding any pitfallsManagement can win awards basis the documentationIt is required for the final sign off from process ownerIt eliminates the need for any audits14. Communication of project recommendations must try to include which of 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 completeMonitoring process CTQ periodicallyStarting a new DMAIC project in the subsequent yearEliminating audit and inspection16.
