Run Chart
A run chart is a simple line graph that displays data points in chronological order to monitor process performance over time. It helps identify trends, shifts, or patterns in data, making it a fundamental tool in quality control and process improvement. By plotting sequential observations, it provides a visual representation of variation and helps determine if a process is stable or changing.
Developers should learn run charts when working on projects that require monitoring system performance, debugging issues, or improving software development processes, such as tracking bug counts, response times, or deployment frequencies. They are particularly useful in Agile and DevOps environments for visualizing metrics like sprint velocity or incident rates to make data-driven decisions and identify anomalies early.
