CSSGB · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Overview: Six Sigma and the Organization & Define

  • Define Six Sigma, lean, and the DMAIC/DMADV roadmaps in your own words and state when each is used

  • Differentiate the key roles (executive sponsor, champion, master black belt, black belt, green belt) and describe their accountabilities

  • Compute and interpret sigma level, DPMO, and rolled throughput yield from given process data

  • Explain how Six Sigma aligns to organizational strategy, including cost of poor quality categories and the balanced scorecard linkage

  • Draft a charter outline that converts a business case into a problem statement, goal statement, and scope boundaries

Your checkpoint

A one-page DMAIC roadmap plus a completed practice charter, scored against a 10-point self-check rubric with no more than one item missed

Week 2

Define

  • Translate a vague customer complaint into a measurable CTQ characteristic with operational definition

  • Construct a SIPOC diagram and identify process boundaries, inputs, and outputs for a chosen process

  • Distinguish VOC collection methods (surveys, interviews, focus groups, observation) and select the appropriate one for a scenario

  • Write SMART problem and goal statements and critique three flawed examples

  • Assemble a project team section including stakeholder analysis and a communication plan

Your checkpoint

A complete project charter package (business case, problem, goal, scope, SIPOC, CTQs, team, milestones) submitted and self-graded at 80% or better

Week 3

Measure

  • Classify data as continuous, discrete, or attribute and choose the correct measurement scale for ten scenarios

  • Build and interpret Pareto charts, histograms, run charts, and stratified frequency plots

  • Calculate descriptive statistics (mean, median, mode, standard deviation, range, IQR) and explain how outliers shift each

  • Compute sigma level and process capability indices Cp and Cpk from given summary data

  • Design a data collection plan including sampling strategy, sample size rationale, and operational definitions for measurement

Your checkpoint

A measurement plan workbook with 25 practice problems on descriptive statistics and capability, scored at 80% or higher

Week 4

Measure & Analyze

  • Interpret measurement system analysis output, distinguishing repeatability from reproducibility and judging acceptability against the 10%/30% rule

  • Perform and interpret a Gage R&R interpretation from a provided ANOVA table summary

  • Explain the difference between accuracy, precision, bias, linearity, and stability with an example of each

  • Identify the correct analysis tool family (graphical vs. hypothesis test) for a stated question about continuous or attribute data

Your checkpoint

A mid-point practice exam of 60 questions covering domains 1 through 3, with every missed item rewritten as a corrected note card

Week 5

Analyze

  • State the null and alternative hypotheses, select the appropriate test, and set alpha for twelve written scenarios

  • Compute and interpret one-sample and two-sample t-tests, paired t-tests, and ANOVA results given summary statistics

  • Apply chi-square and proportion tests to attribute data and explain the meaning of the p-value in plain language

  • Construct and interpret simple linear regression output including R-squared, slope significance, and residual assessment

  • Distinguish correlation from causation and identify confounding in a described study

Your checkpoint

A statistical analysis portfolio of 20 worked hypothesis-testing problems, each with the decision rule, computed statistic, p-value, and business conclusion written out

Week 6

Analyze & Improve

  • Complete root cause analysis using fishbone, 5 Whys, and fault tree techniques on a selected problem, verifying causes with data

  • Generate and prioritize solution ideas using brainstorming, benchmarking, and a weighted decision matrix

  • Apply lean tools including 5S, kaizen, poka-yoke, and standard work to a described process and predict the effect

  • Conduct a basic FMEA by assigning severity, occurrence, and detection ratings and computing risk priority numbers

  • Plan a pilot of a chosen solution including success criteria, sample size, and a rollback condition

Your checkpoint

A solution selection package containing a verified root cause, a weighted decision matrix with at least four options, and an FMEA with the top three RPNs addressed

Week 7

Improve & Control

  • Differentiate statistical process control from pre-control and from process capability studies

  • Select the correct control chart (X-bar and R, individuals and moving range, p, np, c, u) for eight stated scenarios and justify each choice

  • Compute control limits and distinguish special cause from common cause using the standard run rules

  • Design a control plan with the critical process parameters, specification limits, monitoring frequency, and reaction plan

  • Explain the elements of mistake-proofing, visual management, and a documented standard operating procedure for sustaining gains

Your checkpoint

A control plan and control chart interpretation set covering all eight chart types, with correct special-cause calls on 15 out of 15 trials

Week 8

Overview: Six Sigma and the Organization & Define & Measure & Analyze & Improve & Control

  • Review every domain using a gap list built from prior quiz results and re-study only the weak areas

  • Re-derive the formulas most often tested (sigma level, DPMO, Cp and Cpk, control limits, RPN) from memory on a blank sheet

  • Explain the DMAIC flow end to end and state the key deliverable produced at the close of each phase

  • Complete a full-length timed practice exam and analyze errors by domain and by error type

Your checkpoint

One closed-book, timed 100-question practice exam scored at 75% or higher, with a written remediation list for any domain scoring below 70%

Milestones

Week 2: Project charter package self-graded at 80% or higher, confirming Define-phase fluency before moving to statistics

Week 4: Mid-point 60-question exam on domains 1 through 3 scored at 70% or higher

Week 6: Hypothesis-testing portfolio and FMEA solution package both complete, with at least 16 of 20 statistics problems answered correctly

Week 8: Full-length timed practice exam scored at 75% or higher with no domain below 70%
