Six Sigma Fundamentals (Six Sigma and the Organization)
Define Six Sigma and contrast it with Lean, TQM, and traditional inspection-based quality control
Sequence the five DMAIC phases and state the purpose and key deliverable of each
Distinguish the responsibilities of sponsor, champion, process owner, MBB, BB, GB, and Yellow Belt
Calculate sigma level, DPMO, and first-pass yield from defect and opportunity counts
Name the eight lean wastes and tag one real example of each from your own workplace
Your checkpoint
A single-page reference sheet covering DMAIC outputs, belt roles, and the 8 wastes, plus 10 self-worked DPMO/sigma-level problems scored at 9/10 or better against an answer key.
Six Sigma Fundamentals (Six Sigma and the Organization) & Define Phase
Classify 10 real cost items into cost-of-poor-quality categories (prevention, appraisal, internal failure, external failure)
Rewrite a vague complaint as a measurable problem statement with baseline, location, timing, and magnitude
Draft SMART goal statements and a business case with a defensible savings estimate
Construct a SIPOC for a process you own with at least 5 inputs, 5 outputs, and 3-5 customer requirements
Identify project stakeholders and assign each a communication method and cadence
Your checkpoint
A completed project charter (problem, goal, business case, scope, team, milestones) plus a SIPOC diagram for one real process, scored against a 10-point completeness checklist.
Define Phase & Measure Phase
Differentiate voice of the customer, CTQ, and the Kano model categories, and sort 10 requirements into them
Convert three customer needs into CTQs with operational definitions, units, and specification limits
Build a Pareto chart and write the vital-few conclusion that identifies the top contributors
Assess a project against Define-phase tollgate criteria and list any gaps before proceeding
Outline a data collection plan naming what to measure, the operational definition, and the data owner
Your checkpoint
A CTQ tree plus a Pareto chart built from real or supplied data, accompanied by a one-paragraph vital-few justification.
Measure Phase
Classify variables as continuous or discrete and as nominal, ordinal, interval, or ratio, then match each to a valid chart
Write operational definitions and a data collection plan with a justified sampling method and sample size
Interpret a Gage R&R result for continuous data and an attribute agreement analysis for discrete data
Compute and explain mean, median, mode, range, and standard deviation, and read a histogram and box plot
Calculate Cp, Cpk, Pp, and Ppk, and translate capability into sigma level and expected DPMO
Your checkpoint
A Measure-phase workbook containing data collection plan, MSA interpretation, and a capability calculation with written conclusion, scored at 80% or higher against an answer key.
Analyze Phase
Generate candidate causes in a fishbone diagram using all six M categories
Drive the most likely causes to a verifiable root cause using the 5 Whys
Weight and rank causes in a cause-and-effect matrix scored against customer importance
Distinguish correlation from causation when interpreting scatter plots and regression output
Select the appropriate test (1-sample t, 2-sample t, paired t, ANOVA, chi-square) for five written scenarios and justify alpha, beta, and p-value interpretation
Your checkpoint
A root cause analysis package for one problem: fishbone, documented 5-Whys chain, C&E matrix, and a paragraph naming the chosen statistical test and why.
Analyze Phase & Improve Phase
Apply stratification and multi-vari thinking to separate within-unit from between-unit variation
Generate solution options through brainstorming and benchmarking, then screen them on an impact/effort matrix
Apply lean improvement tools (5S, kaizen, poka-yoke, standard work, value stream mapping) to one workflow
Design a pilot stating success metric, sample, duration, and go/no-go decision criteria
Explain at a conceptual level how a full-factorial DOE isolates main effects and interactions
Your checkpoint
An improvement plan naming the selected solution, its impact/effort rank, the pilot design, and a projected benefit with the assumption behind it.
Improve Phase & Control Phase
Build a control plan specifying measure, method, frequency, owner, and reaction for each key X
Select the correct control chart type (I-MR, Xbar-R, p, np, c, u) for six data scenarios
Interpret control charts to separate common from special cause and state the standard out-of-control rules
Write an out-of-control action plan with trigger, immediate response, escalation, and verification steps
Error-proof the improved process and document standard work for the new method
Your checkpoint
A control plan plus one plotted control chart with at least three signals correctly identified and matched to the corresponding action-plan response.
Control Phase & Six Sigma Fundamentals (Six Sigma and the Organization)
Verify project closure requirements: results validation, documentation, lessons learned, process handoff, and financial sign-off
Audit a control plan against a 5W1H completeness test and correct every missing element
Complete two timed full-length practice exams and log every missed item by domain
Re-study the two weakest domains until re-quiz performance reaches 80% or higher
Recite from memory the core tools and deliverables associated with each DMAIC phase
Your checkpoint
A domain scorecard built from two timed practice exams, plus a one-page remediation log showing every domain at 80% or higher.
Milestones
Week 2: Explain DMAIC, belt roles, and the 8 wastes without notes, and produce a charter plus SIPOC that passes the 10-point checklist with no missing scope or goal elements.
Week 4: Score 80% or higher on a 25-question Measure-phase quiz and correctly compute Cp/Cpk from raw data with the sigma level stated in the conclusion.
Week 6: Demonstrate a complete fishbone-to-root-cause chain, name the correct hypothesis test for a given dataset, and present a pilot design with explicit go/no-go criteria.
Week 8: Average 80% or higher across two full-length timed practice exams with no single domain below 70%, and every control-chart and DPMO item answered correctly on review.
