EXIN LSSA Six Sigma Black Belt study plan

Distinguish Lean, Six Sigma, and Lean Six Sigma by writing a one-paragraph definition of each plus two situations where each approach alone would underperform

Map the DMAIC roadmap end to end and label the key deliverables and exit criteria of each phase

Compute DPMO, yield, and process sigma from a defect count and unit count, then convert sigma level to approximate DPMO without a table

Identify at least six common Lean wastes in a process you know and rank them by estimated annual cost or time impact

Explain the roles of Champion, Sponsor, Master Black Belt, Black Belt, Green Belt, and process owner and where they sit in a deployment structure

Evaluate the readiness criteria for launching a Six Sigma initiative, including leadership commitment, linkage to strategy, and resource allocation

Produce a stakeholder analysis that classifies stakeholders by influence and interest and states an engagement action for each group

Write a problem statement that is measurable, time-bound, and free of an embedded cause or solution

Draft a SMART goal statement and a business case that ties the project to financial or customer impact

Draft a team charter and a SIPOC for a real process, identifying at least four customers and their CTQ characteristics

Translate customer needs into a prioritized list of CTQs with operational definitions and specification limits

Construct a Kano model classification of at least eight customer requirements and explain which drive satisfaction versus dissatisfaction

Build a CTQ tree from a broad customer need down to measurable characteristics

Select the most appropriate tool among VOC collection methods, affinity diagram, and tree diagram for three different scenarios and justify each choice

Define process boundaries and scope exclusions that prevent scope creep in the charter

Design a data collection plan that specifies what to measure, how, by whom, when, and the operational definition for each metric

Classify each of your CTQ metrics as continuous or discrete and select the appropriate measurement scale

Perform a Gage R&R interpretation using a provided repeatability and reproducibility output, stating whether the measurement system is acceptable and why

Explain the difference between accuracy, linearity, stability, and precision and give a process example of each

Calculate baseline process capability using Cp and Cpk, and explain what Cpk tells you that Cp does not

Construct and interpret a control chart selection guide that matches data type and subgroup size to the correct chart

Build a process map with cycle times and identify where value is added versus where only cost is added

Calculate rolled throughput yield for a multi-step process and compare it with final yield

Distinguish common cause from special cause variation and state the correct management response to each

Compute sample size needs for a given confidence level and margin of error for a proportion

Generate and organize cause hypotheses using a fishbone diagram and a cause-and-effect matrix weighted by customer importance

Build a Pareto chart and apply the 80/20 rule to prioritize the vital few causes

Select the correct hypothesis test for five given scenarios by matching data type, number of groups, and pairing

Interpret a hypothesis test output: state the null and alternative hypotheses, read the p-value, and state the conclusion in process terms

Distinguish statistical significance from practical significance and identify the risks of a Type I versus Type II error in your project

Complete a regression or correlation analysis and interpret slope, R-squared, and residual behavior for a real data set

Verify root causes with data rather than opinion and document the evidence for each confirmed cause

Generate, screen, and select improvement solutions using an impact-effort matrix and a failure mode and effects analysis

Design a pilot or designed experiment to test the chosen solution before full implementation

Plan a control strategy that names the metric, the chart, the reaction plan, and the owner for each critical X

Build a control plan that specifies the standard operating procedure, monitoring method, response plan, and audit frequency for each critical process input

Standardize the improved process with a documented procedure and a mistake-proofing device or check

Calculate and present the financial and operational benefit of the project against the original business case

Prepare a project closure and handover package that transfers ownership to the process owner

Assemble a full practice exam review plan that targets your weakest domain based on your own diagnostic results
