There are a number of activities in a process that are carried in order to convert the input to the desired output. There are different changes that are often seen in the processes. The occurrence of a change in the process is sometimes very productive. The run chart is used to determine the change that occurred and its duration.
What is a run chart?
A run chart is a graph that is used to display the process performance over time. The chart can show the increase or decrease in performance quality. The upward and downward movement of the graph represents the changes in the trends and the user can investigate several other details.
The run chart is made by plotting the event on the y-axis and time on the x-axis. Various parameters are used to display in the run chart. For example, in order to see how quickly the patients are being treated in the hospital, the number of patients and the time period in which each patient is treated can be plotted in the graph. Making such a run chart enables the user to see if there exists some potential for improvement.

A run chart monitors the conduct of a variable over time. It is used for a process graphically displaying trends, shifts, cycles, or haphazard patterns this run chart exhibits in behavior over time. Run charts can serve two purposes
- It identifies problems and when the problem occurred
- It screens progress when solutions are applied
- They display a pattern of data which show deviations as you make alterations
- They direct you for improvement and guide you about the value of significant changes
- Simple to execute
- No statistical training is required
- Displays simple data
For a run chart, product, service, or process are the resources whose analysis has to be done. A reasonable period of time is the other deviator which is calibrated with a control chart.
A dimension error indicates that the measurement process is adequate in the data collection process. The data is stored in chronological or consecutive order. The starting and ending point is of your choice. At least 25 samples are used to apply the procedure. Ordered pairs of x and y values are determined. The values for x characterize time or sequence number, and the values for y signify the product measurement. The Y versus X value is plotted with a standard scale. Vertical lines are plotted for the x values for separate time intervals.
What are the benefits of a run chart?
One of the most commonly used process improvement tools is run chart which is not only powerful but also very simple and easy to use. Some of the key benefits of the run chart are:
- The run chart is a very effective tool for determining if the process is undertaking the changes in central tendency.
- There is no need to perform complex calculations or use any software to create a run chart. However, it should be kept in mind that these charts don’t have a number of analytical techniques just like other statistical tools
- The main focus of the run chart is on the vital changes appearing in the process. In this way, this chart traces the improvements in the chart. Even if the changes are not bringing any improvement in the process, the run chart can tell the user about the stagnation in the progress of the process so that he can take some necessary steps.
