1What is the primary aim of Six Sigma as described in CSSC Green Belt study topics?
A.Reduce process variation and defects using a disciplined, data-driven method
B.Replace all inspection with final product audits
C.Focus improvement work only on employee productivity
D.Use brainstorming instead of measurement to speed decisions
Explanation: Six Sigma is a disciplined approach for improving processes by reducing variation and defects. Green Belts are expected to connect customer requirements, data, and process improvement rather than relying on opinion alone.
2Which statement best describes the role of a CSSC Green Belt on a Six Sigma project?
A.Lead or support improvement projects using DMAIC tools, often with guidance from higher belt levels
B.Approve the organization's entire Six Sigma deployment strategy
C.Perform only data entry after a Black Belt completes the analysis
D.Serve only as a financial sponsor for project funding
Explanation: Green Belts are practitioners who understand the Six Sigma roadmap and tools well enough to lead smaller projects or support larger projects. They are not limited to clerical work, but they also are not normally the top-level deployment authority.
3In Six Sigma terminology, what is a defect?
A.Any failure to meet a defined customer or process requirement
B.Any product feature that is expensive to produce
C.Any process step that takes more than one minute
D.Any variation from the team's preferred work style
Explanation: A defect is a failure to meet a specification, requirement, or customer expectation. The definition must be operational enough that different people can classify the same item consistently.
4Which metric is most directly associated with the Six Sigma benchmark of very low defect rates?
A.Defects per million opportunities
B.Average employee tenure
C.Annual training hours per person
D.Total number of meetings held
Explanation: Defects per million opportunities, or DPMO, normalizes defects by the number of opportunities for defects and scales the result to one million opportunities. It allows different processes to be compared more fairly than raw defect counts alone.
5What does voice of the customer work try to capture?
A.What customers need, expect, value, or complain about in relation to the process output
B.Only the opinions of the project sponsor
C.The finance department's preferred cost reduction target
D.The exact control limits for a control chart
Explanation: Voice of the customer, or VOC, captures customer needs and expectations so the team can define meaningful requirements. Those needs are often translated into CTQ characteristics that can be measured.
6Which example is a critical-to-quality, or CTQ, requirement?
A.Orders must ship within 24 hours of approval
B.The team should try harder during peak season
C.The manager wants fewer complaints someday
D.The department prefers the old software screen
Explanation: A CTQ requirement is a measurable characteristic that matters to the customer. Shipping within 24 hours is specific enough to measure, analyze, and improve.
7Which cost is an example of cost of poor quality?
A.Scrap and rework caused by defects
B.Preventive maintenance that avoids defects
C.Training employees on a new standard work method
D.Designing a mistake-proof fixture before launch
Explanation: Cost of poor quality includes losses caused by poor performance, such as scrap, rework, returns, warranty work, and complaint handling. Prevention costs may be part of the broader cost of quality model, but they are not poor-quality failures.
8Which statement best describes process variation?
A.Differences in process outputs or conditions over time
B.A required difference between every customer's order
C.A financial variance from the project budget only
D.The number of people assigned to a project
Explanation: Variation means process performance is not identical from unit to unit or moment to moment. Six Sigma projects seek to understand whether that variation is expected common cause variation or a signal of special causes.
9What is the main purpose of a SIPOC diagram in the Define phase?
A.Show suppliers, inputs, process, outputs, and customers at a high level
B.Calculate p-values for a hypothesis test
C.Rank root causes by failure mode risk priority number
D.Create detailed operator work instructions for every task
Explanation: A SIPOC gives the team a high-level boundary view of the process and its upstream and downstream relationships. It is especially useful early in a project before detailed mapping begins.
10Which item belongs in a project charter?
A.Problem statement, goal, scope, business case, timeline, and team roles
B.Every raw data value collected during the project
C.The final control chart limits before measurement begins
D.A list of personal opinions about who caused the problem
Explanation: A charter documents why the project exists, what it will address, how success will be measured, and who is involved. It aligns stakeholders before the team invests heavily in data collection and analysis.

CSSC Green Belt: Suggested Study Strategy

1Use the CSSC Body of Knowledge as the outline and make sure every DMAIC phase is covered.
2Memorize and practice defect metrics such as DPU, DPO, DPMO, first time yield, and rolled throughput yield.
3Know how to choose between variable and attribute control charts, including p, np, c, u, I-MR, and X-bar/R charts.
4Practice interpreting p-values, alpha risk, beta risk, Type I errors, Type II errors, and statistical power.
5Connect Lean waste reduction to Six Sigma variation reduction so scenario questions do not feel isolated.
6Because the standard exam is open-book but timed, organize formulas, chart-selection rules, and DMAIC tool summaries for fast lookup.
