When should run charts be utilized?

Run charts are a valuable tool for analyzing the performance of a process over time. They display data points in a time-ordered sequence, allowing teams to visualize trends, patterns, or variations in process performance. By plotting data chronologically, run charts help identify shifts, cycles, or any anomalies in the process, making it easier to assess whether changes made to a process lead to improvements or if issues are recurring.

The use of run charts is particularly advantageous in Six Sigma and continuous improvement initiatives, as it supports data-driven decision-making by illustrating the effects of changes in a process clearly. This visual representation can guide further analysis and inform future actions, helping organizations maintain a focus on process performance over time.
