This is an analysis of the practice bank, not a claim about the vendor's live exam blueprint. Use it to identify the knowledge, judgment, and recall patterns exercised here, then verify your coverage against the current official exam guide.
The practice bank extensively tests the five phases of DMAIC. In Define, project goals and scope are established via a Project Charter. Measure focuses on data collection reliability through Measurement System Analysis (MSA) and process capability. Analyze uses tools like scatter plots and Fishbone diagrams to identify root causes. Improve validates solutions with pilot tests, and Control sustains gains via control plans and SPC. Each question requires recognizing which phase a specific activity belongs to and its primary objective.
This practice set covers essential Six Sigma tools. Process Capability Analysis measures the process against customer specifications. Hypothesis testing determines statistical significance of differences. Regression analysis models relationships between variables. Control charts monitor process stability. Failure Mode and Effects Analysis (FMEA) proactively identifies potential failures. The 5 Whys technique digs into root causes. Each tool's purpose and typical phase of use are tested, requiring understanding of when and why to apply them.
The practice bank highlights Lean Six Sigma's emphasis on waste reduction and efficiency. Value Stream Mapping (VSM) identifies bottlenecks and non-value-added activities. The 5S methodology (Sort, Set in Order, Shine, Standardize, Sustain) organizes the workplace. ISO 9001 is referenced as a quality management standard. Understanding that Lean focuses on flow and waste while Six Sigma reduces variation is key. The questions test recognition of Lean tools and how they complement the DMAIC framework.
The practice set clarifies the Green Belt's responsibilities within a Six Sigma team. Green Belts conduct data analysis, assist Black Belts, and lead smaller projects. They must know when to apply specific tools and interpret outputs. Questions emphasize the Green Belt's role in collecting data, performing statistical analysis, and supporting project execution. The distinction from Black Belts and Champions is important, as is understanding the project lifecycle from chartering through control.
Study workflow
Start with a Project Charter that states the problem, goals, business case, stakeholders, and timeline. Ensure the scope is narrow enough for a Green Belt project. Validate with the project sponsor and champion to align expectations.
Before gathering data, assess the measurement system for accuracy and precision. Use gage R&R studies to quantify measurement variation. Only trustworthy data should proceed to the Analyze phase.
In the Analyze phase, use Fishbone diagrams to brainstorm causes, then apply 5 Whys to drill down. Validate hypotheses with data (e.g., scatter plots, hypothesis tests). Prioritize root causes based on impact and feasibility.
During Improve, design solutions targeting validated root causes. Run a pilot test on a small scale to measure effectiveness. Document results and refine solutions before full rollout to reduce risk.
In the Control phase, develop a plan with control charts, reaction limits, and responsibilities. Train process operators. Monitor key metrics to ensure improvements are sustained and adjust as needed.
