LSS artifacts, all Green-Belt appropriate. Pair them for a complete DMAIC project.

Artifact	Type	Version	Last tested
DMAIC Template	Script	v1.0.0	2026-06-03
Fishbone	Skill	v1.0.0	2026-06-03
Pareto	Script	v1.0.0	2026-06-03

How they fit together

D (Define)    → dmaic-template   (problem statement, charter, SIPOC, VOC)
M (Measure)   → pareto           (vital few from a defect log)
A (Analyze)   → fishbone         (root causes from the vital few)
I (Improve)   → [your pilot]     (write the pilot plan in the DMAIC markdown)
C (Control)   → [your plan]      (control plan is the bottom of the DMAIC markdown)

Quick example — "Reduce NPT on Well A-12"

1. Define — dmaic.py --input problem.example.yaml --output dmaic.md → 114-line project charter
2. Measure — pareto.py --input npt_log.csv --column "Cause" --output pareto.svg → identify the vital few
3. Analyze — fishbone.py --input problem.example.yaml --output fishbone.svg → root causes on 6 bones
4. Improve + Control — edit the I-Improve and C-Control sections of dmaic.md
