Professional Lean Six Sigma Visuals

Transform raw data into production-ready Lean Six Sigma (LSS) assets. This skill handles the heavy lifting of statistical calculations and complex diagramming, delivering actual files (HTML, XLSX, PNG, SVG) rather than simple text descriptions. Whether you are a Green Belt building a Pareto chart or a Master Black Belt conducting a full Capability Analysis, this tool ensures your visuals meet rigorous industry standards.

What it does

• Statistical Process Control (SPC): Generates I-MR, X-bar R/S, p, np, u, and c-charts with automated Western Electric Rule detection and out-of-control highlighting.
• Quality & Analysis: Produces Pareto charts with 80/20 lines, Histograms with Normal curve overlays, Box Plots, and Scatter Plots with regression intervals.
• Lean Mapping: Creates interactive Fishbone (Ishikawa) diagrams, Value Stream Maps (VSM), SIPOC diagrams, and Spaghetti diagrams.
• Project Templates: Generates editable Excel worksheets for FMEA, Gage R&R, OEE calculators, and Project Charters with built-in formulas and conditional formatting.

Why use this skill?

Prompting a standard AI often results in broken SVG code or hallucinated statistical limits. This skill uses precise Python libraries (Plotly, Matplotlib, Openpyxl) to perform exact calculations and apply expert color-coding (e.g., specific markers for out-of-spec data). It follows colorblind-friendly professional palettes and outputs files ready for C-suite presentations or technical documentation.

Supported Outputs

• Interactive HTML (Plotly): For charts that require exploration and tooltips.
• Editable XLSX: For templates requiring data entry and formula logic.
• Scalable SVG/PNG: For static reports and publication-quality diagrams.
