Definition

Data analysis software refers to digital tools that help users collect, process, visualize, and interpret data to uncover patterns, test hypotheses, and support decision-making. These tools are essential in process improvement and Lean Six Sigma for analyzing variation, performance, and root causes.

Examples

A Black Belt uses data analysis software to conduct a Hypothesis Test comparing cycle times before and after a process improvement initiative. The software helps them determine if the change led to a statistically significant improvement.

Application

In Lean Six Sigma, data analysis software is used to perform statistical tests, create control charts, build regression models, and generate visualizations that guide improvement efforts. It allows practitioners to validate assumptions, identify trends, and quantify the impact of process changes.
