Capability, proven
Tools to judge whether a process can actually hold its tolerances: drop in your measurements, fit the right distribution, and read capability against spec. Open a read‑only preview anytime; create a free account to fill them in and save your work.
Measure, fit, and prove capability
Drop your inspection data and let the tool do the statistics: histograms, distribution fits, Cp / Cpk against your spec limits, full Gauge R&R on your measurement system, and SPC control charts that prove the process is stable.
Capability Analysis & Distribution Fit
Drop a column of measurements and get a histogram with a fitted distribution, Cp / Cpk / Pp / Ppk against your spec limits, and the tolerance needed to reach a chosen Cpk, for every dimension in one study.
Gauge R&R & Measurement‑System Analysis
Generate a randomized run sheet, record each operator’s repeated readings, and get %GRR, ndc, ANOVA, and the standard MSA charts, with a clear accept / marginal / reject verdict and a recommendation for every dimension.
Measurement System Analysis
The accuracy side of MSA, alongside Gauge R&R. Measure a known master to get bias significance & Type-1 (Cg / Cgk), check linearity across the working range, and chart stability over time, for every dimension in one study.
Control Charts & Process Stability
Plot I‑MR, X̄‑R, X̄‑S, p, and np charts from your data. The tool sets the 3σ limits, flags out‑of‑control signals and, once stable, reads Cp / Cpk right alongside.
Chart Builder
Type or paste your data into a live grid, then turn it into a bar, grouped, stacked, line, area, scatter, pie, donut or combo chart, branded and ready to drop into a report. Export to PDF, PNG, or SVG.
Trend a part’s capability over time
Save your capability and Gauge R&R studies to a supplier folder, then roll them into one Performance Report: worst‑case Cp / Cpk / Ppk and %GRR / ndc per dimension, quarter over quarter, against the 1.33 and 1.67 capability lines.
Branded, watermarked, and yours to use
These aren't generic worksheets. Every page is built to the Vanguard standard.
Diagonal VQP watermark
A subtle tiled Vanguard Quality Partners watermark sits behind every template, so a saved or shared PDF always shows where it came from.
