Lean Six Sigma Black Belt Sample Paper 2: Background This sample paper will check your knowledge on Background for LSS Black Belt Click on 'Next' to start 1. Which of the following statement about Six Sigma is NOT true?Six Sigma as a set of tools includes both qualitative and quantitative techniques used to drive process improvementDMAIC is the only Six Sigma methodology adopted and recognized by the IndustrySix Sigma quality performance means 3.4 DPMO (accounting for 1.5 sigma shift in the mean)Six Sigma recognizes the underlying and rigorous approach known as DMAIC, starting with identifying the problem and ending with the implementation of long-lasting solutions2. “Six Sigma” used as a process performance metric means ___________We can accommodate 6 standard deviations between the mean and the specification limitThe process width is ± 3 standard deviations from the meanThe specification width is 6 standard deviationsAll the above3. Identify the odd-one-out from the followingNormal distributionPoisson distributionBinomial distributionDiscrete-Uniform distribution4. “Data collection for primary and secondary metrics to gain insight and establish baseline”, is the main purpose of ______________Define phaseControl phaseAnalyze phaseMeasure phase5. When speed is essential, and survival of the organization is at stake, which of the following approach is best suited for dealing with resistance to change?Education and communicationParticipation and involvementImplicit and explicit coercionFacilitation and support6. In case of a perfect normal distribution ____________The mean, median and mode are the sameThe median does not existMean and median are same, but mode is differentMean is higher than median7. Six Sigma Level can be achieved by having _____________less than 3.4 defects per million opportunitiessix levels of testing before releasesix times better quality than baselineSix Nines Quality (99.9999%)8. What strategy should be used for “Low importance and high commitment” stakeholders?Minimize dependency on this type of stakeholderProtect and defend these stakeholdersMonitor these stakeholders, but don’t spend resources on themThese stakeholders are capable of sabotaging plans, escalating problems and are considered high risk9. When the VP of a small company announced to his managers that the company would implement a flexible working schedule for all employees, numerous rumors began to circulate as none of them knew what flexible working hours meant. One rumor, for instance, suggested that flexible hours meant that most people would have to work whenever their supervisors asked them to—including evenings and weekends resulting in high resistance. It never occurred to the VP, that he might run into such a resistance. What is the most appropriate reason for this resistance?Parochial self-interestMisunderstanding and lack of communicationLow tolerance to changeAll the above10. Which one of the following is NOT one of the eight steps from John Kotter’s book “Leading Change”?Create short term winsMake change stickIdentify resistors to changeCreate a sense of urgency11. Which of the following statement is incorrect?Kanban is Japanese for “Visual signal” or “Signal card”Kanban can only be implemented using visual indicator called Kanban cardsJust-in-Time manufacturing in Toyota uses Kanban cards as a signal between two dependent processes to facilitate smoother and just in time flow of parts between themIn a pull system, the process produces only when there is a pull (demand) from the subsequent process, signaled as a Kanban card12. Which of the following statement is true?If the process behaves consistently over time, then we say that the process is capableKnowing about process stability makes us rest assured about process capabilityProcess capability assessment should only be performed after first demonstrating process stabilityProcess stability is a measure of the ability of the process to meet specifications13. All the examples below are of discrete data, EXCEPT _________________Number of complaintsHoursNumber of defectsNumber of tickets raised14. Likert-type data is an example of ________________Continuous dataNominal dataOrdinal dataBinary data15. The purpose of Toll Gate review is to _____________review progress and kick off the next phaseget a formal sign-off from the stakeholdersconfirm if the earlier phase was completed successfullyAll the above16. __________ is a graphical tool of choice to show frequency distribution of discrete data.Bar graphHistogramBox plotScatter plot17. Which of the following statement is INCORRECT?For a large dataset, calculation of standard deviation is preferred over rangeFrom the standard deviation one can derive the minimum and the maximum values of the datasetCalculation of range uses only two values from the datasetTo reduce the problems caused by outliers in a dataset, the inter-quartile range is often calculated instead of the range18. Which of the following is true for a standard normal distribution?Mean = 0, Standard deviation = 1Mean = 1, Standard deviation = 1Mean = 0, Standard deviation = 0Mean = 1, Standard deviation = 019. __________ provides a quick look at the planned activities, schedule, allows for assessment of key resources and project performance against plan.Control chartGantt chartPlanning chartRun chart20. Which of the following statement is NOT true with respect to RACI matrix?Responsible: The individual ultimately responsible for the resultsResponsible and accountable can be the sameResponsible: Individuals who actively participate in an activityThere could be many responsible but only one accountable21. According to B. W. Tuckman’s “Developmental Sequence in Small Groups”, which of the following is NOT an attribute of the “FORM” stage of team formation?Group is going through the “honeymoon” periodNot much work is accomplishedTeam members exhibit high agreement on initial discussion topicsTeam members resolve their conflicts22. Turnaround time (TAT) data collected shows normal distribution with a mean of 5 and a standard deviation of 1. What are the chances that the TAT will be between 4 and 6?68%95%99%Not enough information to calculate23. Which of the following statement is true about variance?It is the square of standard deviationIt has the same unit as that of the meanIt has the same unit as that of the dataIt is a measure of central tendency24. All the following statements are true, except _________DMADV is mostly used when a process or a product is not in existence and one needs to be developedDMADV can be used if the current product/process exists, has been optimized but still doesn’t meet customer/business expectationsDMADV can be used in research and developmentDMADV is a reactive approach25. Kaizen is a Japanese term for “change for improvement” or improving processes through small incremental steps. Breakthrough improvement is referred to by another Japanese term, which is ___________KanbanKaikakuHoshin KanriGembutsuTime is Up!
