Why are run charts essential in process improvement?

Run charts are essential in process improvement primarily because they allow for the easy identification of potential performance issues. By plotting data points over time, run charts visually display trends, shifts, or patterns within a process, making it easier for teams to observe how a process is behaving. This ability to see variations from the norm can lead to insights that drive necessary adjustments or improvements in the process.

In contrast to the other options, run charts do not specifically contribute to employee morale, as that is more a result of workplace culture and management practices. While they present historical data points, run charts do not treat all data points equally; rather, they focus on trends over time, which means some more recent data may be more relevant in understanding current process performance. Lastly, run charts do not provide financial forecasts, as they serve primarily as a tool for analyzing process performance rather than financial data analysis.
