Linking Six Sigma projects to strategic goals
Project selection criteria: financial impact, feasibility, and strategic alignment
DMAIC vs DMADV (Design for Six Sigma): when to use each

Voice of the Customer

VOC collection methods: surveys, interviews, focus groups, complaint analysis
Kano model: basic, performance, and excitement needs
CTQ (Critical to Quality) tree: translating customer needs to measurable requirements
QFD (Quality Function Deployment) and House of Quality
SIPOC diagram: Suppliers, Inputs, Process, Outputs, Customers

Lean Fundamentals

Five Lean principles: value, value stream, flow, pull, perfection
Eight wastes (TIMWOODS): Transport, Inventory, Motion, Waiting, Over-processing, Overproduction, Defects, Skills
Value-added vs non-value-added activities
Value stream mapping (VSM): current state and future state maps

Weight

Questions

Marks

Data Types and Collection

Variable (continuous) vs attribute (discrete) data
Data collection plan: who collects, how, when, and where
Sampling methods: random, stratified, systematic
Check sheets, Pareto charts, and histograms for initial data summary
Operational definitions: defining what you are measuring precisely

Measurement System Analysis (MSA)

Gauge R&R (Repeatability and Reproducibility): assessing measurement variation
Bias, stability, linearity, and resolution in measurement systems
%R&R < 10%: acceptable; 10–30%: may be acceptable; >30%: unacceptable
Attribute MSA: Kappa statistic for categorical agreement
Sources of measurement error and how to reduce them

Capability Metrics

Process capability indices: Cp, Cpk, Pp, Ppk
Cp: potential capability (centred process); Cpk: actual capability (includes mean shift)
Six Sigma targets: Cpk ≥ 1.33 (4σ), Cpk ≥ 1.67 (5σ)
DPMO (Defects Per Million Opportunities) and sigma level conversion
Rolled Throughput Yield (RTY) and First Pass Yield (FPY)
Baseline sigma calculation from defect rate

Analyse Phase

Covers root cause analysis, statistical hypothesis testing, regression, and identifying key process inputs (Xs).

Marks

Root Cause Tools

Cause-and-effect (fishbone / Ishikawa) diagram: 6M categories
5 Whys technique: iterative questioning to root cause
Fault tree analysis (FTA): top-down failure analysis
Failure Mode and Effects Analysis (FMEA): RPN = Severity × Occurrence × Detection
Affinity diagrams and interrelationship digraphs

Hypothesis Testing

Null hypothesis (H₀) vs alternative hypothesis (H₁)
Type I error (α, false positive) and Type II error (β, false negative)
p-value interpretation: p < α → reject H₀
t-tests: one-sample, two-sample (independent), and paired t-test
ANOVA: comparing means across more than two groups
Chi-square test: testing independence of categorical variables

Correlation and Regression

Pearson correlation coefficient (r): strength and direction of linear relationship
Simple linear regression: equation, R², and residual analysis
Multiple regression: interpreting coefficients and interaction terms
Scatter plots and identifying outliers and influential points
Regression assumptions: linearity, normality of residuals, homoscedasticity

Non-Parametric and Other Tests

When to use non-parametric tests: non-normal data, small samples
Mann-Whitney U test: non-parametric alternative to two-sample t-test
Kruskal-Wallis test: non-parametric alternative to one-way ANOVA
Box plots and normal probability plots for distribution assessment

Western Electric rules for detecting special cause variation
Common cause vs special cause variation: responding appropriately
Out-of-control signals: points beyond control limits, runs, trends

Control Documentation

Control plan: process name, input/output, specification, measurement, sample size, frequency, reaction plan
Standard operating procedures (SOPs) and work instructions
FMEA update post-improvement: revised RPN scores
