Lss Visuals is a skill that takes raw data and produces actual output files for Lean Six Sigma workflows rather than text descriptions or approximate code snippets. It covers four main areas. For Statistical Process Control, it generates I-MR, X-bar R/S, p, np, u, and c-charts with automated Western Electric Rule detection and visual highlighting of out-of-control points. For quality analysis, it produces Pareto charts with 80/20 lines, histograms with normal curve overlays, box plots, and scatter plots with regression intervals. For lean process mapping, it creates interactive Fishbone (Ishikawa) diagrams, Value Stream Maps, SIPOC diagrams, and Spaghetti diagrams. For project management, it generates editable Excel worksheets covering FMEA, Gage R&R, OEE calculators, and Project Charters, each with built-in formulas and conditional formatting.

Output formats depend on the chart type: interactive HTML via Plotly for exploratory charts with tooltips, editable XLSX for templates requiring data entry, and SVG or PNG for static reports and presentation slides. The skill uses Plotly, Matplotlib, and Openpyxl for calculations and applies colorblind-friendly professional palettes. This is intended for Green Belts, Black Belts, and quality engineers who need finished assets for documentation or C-suite presentations without manually coding charts.

Use cases

Generate an I-MR control chart with Western Electric Rule violations highlighted from process measurement data

Build a Pareto chart with an 80/20 cumulative line from a defect frequency table

Create an interactive Value Stream Map as an HTML file for a manufacturing process review

Produce an editable FMEA Excel worksheet with conditional formatting and severity scoring formulas

Create a Fishbone (Ishikawa) diagram as an SVG for root cause analysis documentation

Generate an OEE calculator spreadsheet with built-in formulas for a production reporting template

When to use it

When an agent needs to deliver finished chart files (HTML, XLSX, PNG, SVG) rather than describe how to make them

When SPC charts require statistically accurate control limits and automated rule detection

When a project requires standard LSS templates such as FMEA, Gage R&R, or Project Charters in Excel format

When lean mapping artifacts like VSMs or SIPOC diagrams are needed for process documentation

When not to use it

When the use case has no relation to Lean Six Sigma, quality engineering, or statistical process control

When the target environment cannot receive or render file outputs such as HTML, XLSX, PNG, or SVG

When purely textual analysis or narrative reporting is needed rather than visual or file-based output

When a general-purpose database query or data pipeline tool is required rather than a visualization skill
