ICBB study plan

ICBB · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Define

  • Define Six Sigma and explain how it differs from prior quality approaches such as TQM and lean, in your own written words

  • Distinguish CTQ from CTC from CTP and map at least three voice-of-customer statements to each category

  • Calculate rolled throughput yield and DPU for a simple two-step process and interpret the gap between them

  • Classify each of the seven muda plus the classic seven wastes in a process you personally know

Your checkpoint

A one-page definitions sheet with 15 key terms, each defined in one sentence, plus a worked RTY/DPU example with correct arithmetic

Week 2

Define & Measure

  • Compare the DMAIC roadmap against DMADV and select the correct one for three short scenarios

  • Identify the roles of Champion, Sponsor, Master Black Belt, Black Belt, Green Belt, and process owner in a governance chart

  • Build a SIPOC for a real process and validate it against a stakeholder

  • Draft a problem statement that passes the SMART and 'no cause, no solution' tests

  • Convert a vague business complaint into a measurable project charter with scope boundaries

Your checkpoint

A complete project charter (problem statement, goal statement, scope, business case, team, milestones) for one real process, reviewed against a 10-point checklist

Week 3

Measure

  • Construct a data collection plan that specifies operational definitions, sampling method, and measurement frequency

  • Perform an MSA for a variable gauge and calculate repeatability and reproducibility components

  • Perform an attribute agreement analysis and report within-appraiser and between-appraiser agreement

  • Distinguish accuracy from precision and linearity from stability using plotted examples

  • Calculate process sigma level and Z-bench from DPMO for both short-term and long-term data

Your checkpoint

An MSA report on a real or simulated gauge with %GRR calculated, a verdict against the 10%/30% rule, and a corrective recommendation

Week 4

Measure & Analyze

  • Build a Pareto chart from a defect dataset and state the vital few in one sentence

  • Construct and interpret run charts and control charts to separate common from special cause variation

  • Calculate Cp, Cpk, Pp, and Ppk for a dataset and explain why the pairs differ

  • Describe process capability in a written summary that a non-technical sponsor could act on

  • Select the correct baseline metric for a project and justify the choice

Your checkpoint

A capability analysis report containing a histogram with specification limits, a control chart, Cp/Cpk/Pp/Ppk values, and a one-paragraph interpretation

Week 5

Analyze

  • Formulate a hypothesis test for a means comparison and state the null and alternative correctly

  • Run and interpret a two-sample t-test, a paired t-test, and a one-way ANOVA on sample data

  • Check normality and equal-variance assumptions and choose an appropriate alternative when violated

  • Compute and interpret correlation coefficients and fit a simple linear regression with residual checks

  • Distinguish statistical significance from practical significance using confidence intervals

Your checkpoint

A statistical analysis memo with three tests performed, assumptions checked, p-values and confidence intervals reported, and a plain-language conclusion for each

Week 6

Analyze & Improve

  • Build a cause-and-effect diagram and a C&E matrix to prioritize at least six candidate causes

  • Perform a multi-vari or FMEA to narrow root cause candidates and score risk priority numbers

  • Verify a root cause with data rather than opinion and document the evidence chain

  • Use hypothesis test results to confirm or reject the suspected root cause

  • Select the appropriate lean or DOE tool for a given improvement scenario

Your checkpoint

A root cause verification package containing a C&E matrix, an FMEA excerpt with RPNs, and the statistical evidence that confirms the chosen cause

Week 7

Improve

  • Design a 2-level factorial experiment with at least three factors and define response, factors, levels, and replicates

  • Analyze main effects and interactions from factorial output and state which factors matter

  • Apply 5S, poka-yoke, and standard work concepts to a chosen process and predict the effect

  • Run a pilot of a proposed solution and compare before-and-after performance with a hypothesis test

  • Quantify improvement in sigma level and financial terms

Your checkpoint

A solution pilot report with a DOE design table, effect estimates, before-and-after comparison, and the projected annualized benefit in currency units

Week 8

Control & Improve

  • Build a control plan naming the metric, owner, specification, chart type, sampling plan, and reaction plan

  • Create an SPC chart with control limits and document the out-of-control rules applied

  • Standardize the improved process with updated work instructions and a mistake-proofing check

  • Calculate the control phase benefit and hand off ownership to the process owner with a signed closure

  • Write a lessons-learned and replication plan identifying where else the solution applies

Your checkpoint

A control plan plus an SPC chart with documented reaction plan, and a one-page project closure summary signed off by the process owner

Milestones

Week 2: Can define all Domain 1 terms without notes and defend a project charter against the 'no cause, no solution' rule in under 10 minutes

Week 4: Passes a 30-question self-quiz on Define and Measure content at 80% or better, and has a completed MSA and capability report in the portfolio

Week 6: Correctly selects and interprets the right hypothesis test for five different scenarios, and has a verified root cause with statistical evidence

Week 8: Completes a full timed 100-question mock exam covering all five domains at 75% or better, with no domain below 60%, and holds a complete project portfolio from charter to control plan
