Statistical process control where the data already is
Control charts and capability studies for shop-floor and Six Sigma work, without shipping files to a desktop license server.
Open SpcLiteThe problem
Quality teams need trustworthy control limits, rule violations, and capability indices — often on shared PCs or locked-down networks where installing desktop stats software is slow or forbidden.
What SpcLite does
- Variable charts: I-MR, Xbar-R, Xbar-S with Rbar / Sbar / pooled σ options
- Attribute charts: p, np, c, u — including unequal subgroup step limits
- Eight Western Electric / Minitab-style tests for special causes
- Run chart and stage labels for multi-phase processes
- Capability: normal, Box-Cox, binomial, and Poisson with Pp/Ppk, Cp/Cpk, Z.Bench, PPM
Typical outputs
Chart panes with UCL/CL/LCL, out-of-control points called out by rule number, capability histograms, and session reports you can print to PDF.
