Six Sigma (6σ) is a set of techniques and tools for process improvement. It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1][2] Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.

This Lean Six Sigma Graphs and Statistics reference guide contains a short explanation for when to use each graph or statistical test and where to find it in Minitab.

Graphical analysis is one of the best ways to analyze problems in Six Sigma projects. It is an effective way to visualize data patterns and provides key insights into the data.

Mar 7, 2024 · Control charts play a vital role in continuous process improvement methodologies like Six Sigma. They facilitate data-driven decision-making by revealing issues like shifts, …

Feb 12, 2019 · A Six Sigma control chart is a simple yet powerful tool for evaluating the stability of a process or operation over time. Creating a control chart requires a graph that covers a period of time, a center line that shows the results of a process during that time, and upper and lower control limits that indicate whether process variation is within ...

A run chart is a basic graph displays data as they evolve over time. Simple rules can be useful for identifying trends or shifts in process.

In this video, you’ll learn about the most pop­u­lar types of graphs used by Lean and Six Sig­ma prac­ti­tion­ers, as well as how and when to use them. Keep in mind — many graphs are designed to work with vari­able data while oth­ers are designed to work with attribute data.

In this video learn what some of the most pop­u­lar types of graphs are and when and how to use them. In this sec­tion we’re intro­duced to both lean and six sig­ma while also learn­ing how they …

Learn how to choose the right Six Sigma chart based on the type of data you have.
