Cp and Pp: Two Capability Indices That Should Not Be Confused Capability indices are used to quantify a process's ability to produce parts that meet specifications. Among...

Before beginning mass production, every quality team must answer a fundamental question: Is my process physically capable of producing within specifications? It’s not...

X̄-R Control Chart: What Are the Red Lines For? On an X̄-R control chart, operators see dots and blue lines scrolling by, and—often...

If you've ever opened a capability report in Ellistat looking for the Cpk, you didn't find it. This isn't an oversight. It's a deliberate, well-founded choice...

For decades, the same thing has been repeated in industrial statistics courses: in experimental design, everything was developed based on Fisher's work (1926, then...

Choosing statistical software for an industrial site involves much more than just a licensing budget. An ill-suited tool slows down analyses, discourages field teams, and ultimately ends up being...
