Six Sigma Green Belt Six Sigma & the Organization Practice Questions

Six Sigma & the Organization makes up 6 of every 50 questions on a Tigertest Six Sigma Green Belt practice test. Here are 10 of the 24 questions on it, each with the answer and the reason.

Updated by the Tigertest team. Based on the ASQ CSSGB Body of Knowledge (2022). Original questions; 50 per test, weighted like the real exam, with a 70% readiness line. Not affiliated with ASQ.

  1. 1. Which quality pioneer introduced the control chart while working at Bell Laboratories?

    • A.Kaoru Ishikawa
    • B.Walter Shewhart
    • C.W. Edwards Deming
    • D.Joseph Juran

    Answer: B. Shewhart developed the control chart in the 1920s to separate common cause from special cause variation. Deming later spread his ideas, including the PDSA cycle he credited to Shewhart.

  2. 2. Joseph Juran's quality trilogy is made up of which three processes?

    • A.Define, measure and analyze
    • B.Inspection, auditing and review
    • C.Plan, do, check and then act
    • D.Planning, control, improvement

    Answer: D. Juran's trilogy is quality planning, quality control and quality improvement. Plan, do, check is part of the PDCA cycle, not the trilogy.

  3. 3. Kaoru Ishikawa is best known in Six Sigma for which tool?

    • A.The fishbone diagram
    • B.The process capability index
    • C.The Pareto chart
    • D.The control chart

    Answer: A. Ishikawa popularized the cause and effect (fishbone) diagram and quality circles. Juran popularized the Pareto principle, and Shewhart developed the control chart.

  4. 4. What is the main financial reason an organization launches a Six Sigma program?

    • A.To replace its audit program
    • B.To win an industry quality award
    • C.To cut the cost of poor quality
    • D.To raise headcount in quality

    Answer: C. Six Sigma ties every project to measurable business results, mostly by reducing defects, rework and waste that make up the cost of poor quality.

  5. 5. A project goal reads: "Cut invoice errors from 4.2% to 1.5% by the end of Q3." Which SMART element does the date satisfy?

    • A.Achievable
    • B.Relevant
    • C.Time-bound
    • D.Measurable

    Answer: C. SMART stands for specific, measurable, achievable, relevant and time-bound. The end-of-Q3 deadline makes the goal time-bound; the percentages make it measurable.

  6. 6. Why should a Green Belt link a project to the organization's strategic goals before starting?

    • A.So leaders fund and support it
    • B.So no metrics are needed
    • C.So the team can be kept smaller
    • D.So the charter can be skipped

    Answer: A. Projects aligned with strategy get sponsorship, resources and attention. A project that solves a local problem nobody at the top cares about tends to stall.

  7. 7. A balanced scorecard tracks performance from which four perspectives?

    • A.Suppliers, inputs, outputs, customers
    • B.Cost, quality, delivery, safety, morale
    • C.Strategy, operations, people, finance
    • D.Financial, customer, process, learning

    Answer: D. Kaplan and Norton's balanced scorecard adds customer, internal process, and learning and growth measures to the financial view, so short-term profit does not hide long-term weakness.

  8. 8. A key performance indicator (KPI) is best described as:

    • A.A cost line in the budget
    • B.A metric tied to a strategic goal
    • C.Any number on a dashboard
    • D.A defect found at final inspection

    Answer: B. A KPI is a measure chosen because it shows progress on a goal that matters to the organization, such as on-time delivery or first-pass yield.

  9. 9. A plant runs 7.5 productive hours per shift and customers need 450 units per shift. What is the takt time?

    • A.16.7 seconds
    • B.60 seconds
    • C.45 seconds
    • D.72 seconds

    Answer: B. Takt time is available time divided by customer demand: 7.5 hours is 27,000 seconds, and 27,000 / 450 = 60 seconds per unit.

  10. 10. A clinic is open 9 hours a day, with a 1-hour lunch closure, and sees 96 patients a day. What is the takt time?

    • A.4.5 minutes
    • B.6 minutes
    • C.5.6 minutes
    • D.5 minutes

    Answer: D. Available time is 9 - 1 = 8 hours, or 480 minutes. 480 / 96 = 5 minutes. Using the full 9 hours gives the 5.6-minute distractor.
