Description
Know your process sigma in seconds — straight from your defect data.
The Attribute Sigma Calculator turns simple pass/fail inspection counts into the numbers quality teams actually report: DPU, DPO, DPMO, first-pass yield and process sigma level. Enter three figures and every result updates instantly — no formulas to look up, no statistical tables.
What it does
- Converts units inspected, opportunities per unit and defects into DPU, DPO and DPMO
- Calculates process sigma with the standard 1.5-sigma long-term shift (adjustable)
- Reports first-pass yield alongside the sigma figure
- Rolls up multiple characteristics into a single combined sigma
- Colour-codes each result red/amber/green so status is obvious at a glance
What’s inside
- Calculator — single-characteristic block plus a multi-characteristic rollup table
- Instructions — plain-English method and definitions
Why use this attribute sigma calculator
Live formulas already wired in, blue input vs. black calculated cells, drop-down validation, and edge cases handled (zero defects, all-defective) so it never throws an error. It matches textbook results exactly — 12 defects in 200 units returns DPMO 60,000 and 3.05 sigma.
Who it’s for
Quality engineers, Six Sigma Green and Black Belts, and process-improvement teams measuring baseline sigma, tracking DPMO, or preparing capability reports.
