DMAIC Define · Measure · Analyze · Improve · Control
Classical Six Sigma improvement cycle for existing processes with measurable output.
Data & Tools

Measure
Phase 2 of the DMAIC cycle — map the process, collect data, validate measurement systems.

MSA Type 1
Measurement System Analysis Type 1 — Repeatability (Cg) and Bias (Cgk)

Fit data to multiple distributions and rank by Goodness-of-Fit test
FMEA
Failure Mode and Effects Analysis with RPN calculation
Hypothesis Test
Variance and mean tests with automatic normality assessment and power analysis
Sample Size

Pairwise Comparison
Prioritize criteria through systematic pairwise comparison. Every criterion is judged against every other.
Outlier Test

Regression Analysis
Polynomial regression (degree 1–3, interactions), Exponential, Logarithmic, Power
Regression (Attributive)
Binary logistic, Poisson, and negative binomial regression for attributive/count data
Response Optimization
Combines several saved regression models and searches for the factor point with the highest joint desirability (Derringer-Suich, multi-start Nelder-Mead).
Control
Phase 5 of the DMAIC cycle — lock in gains and make improvements stick.
