A run chart helps to analyze data. Run charts display trends, variation, and unusual patterns (outliers). Run charts also:
- Summarize occurrences of a particular situation
- Display measurement results over time
- Recognize patterns of performance in a process.
How do process audits and run charts work in conjunction with each other? In the case of a process audit, run charts can track improvements that have been put into place, by checking the successful outputs from the audit.
