Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based tool that turns measurement readings into control charts, capability indices, and a customer-ready report.

Landing page captured for the 2026-10-09 issue.

For: Quality staff at small machine and fab shops
Worth noticing: Its sample flags Western Electric rule violations and shows Cp, Cpk, Pp, and Ppk alongside the charts.

Field notes

The displayed sample pairs each capability index with its calculation basis, distinguishing within-subgroup estimates from overall variation. Its chart example also identifies individual rule violations by point number, while the setup description says shops can paste readings or upload files from measurement equipment.
