What is a run chart in project management?

A run chart is a line graph of data plotted over time. By collecting and charting data over time, you can find trends or patterns in the process. Because they do not use control limits, run charts cannot tell you if a process is stable. However, they can show you how the process is running.

What is a run chart and when is it used?

A run chart is used to study collected data for trends or patterns over a specific period of time. A run chart will help you: Monitor data over time to detect trends, shifts, or cycles.

What is an example of a run chart?

In a run chart, events, shown on the y axis, are graphed against a time period on the x axis. For example, a run chart in a hospital might plot the number of patient transfer delays against the time of day or day of the week.

How is run chart calculated?

To determine the number of runs above and below the median, count the number of times the data line crosses the median and add one. Statistically significant change is signalled by too few or too many runs, again calculated using statistical probability.

What data is needed for a run chart?

Key components of Run Chart

  • Time- series: the specific time period of the output (hours, days, weeks, months); plotted on the horizontal (X) axis.
  • Output: The data measurement from the completed process; plotted on the vertical (Y) axis.
  • Data points: output values plotted on the chart.

What is a Gantt chart PMP?

A Gantt chart is a project management tool that illustrates a project plan. It typically includes two sections: the left side outlines a list of tasks, while the right side has a timeline with schedule bars that visualize work.

Is a run chart a control chart?

A Control chart is a more advanced version of a Run chart. You may hear this chart referred to as a Shewhart chart. Whilst this chart still plots a single line of data, it also displays an upper line for the upper control limit and a lower line for the lower control limit.

How are run charts useful in process control?

The run chart is useful for tracking information and predicting trends or patterns. It can determine if a process has common cause or special cause variation. It can also reveal whether a process is stable by looking for a consistent central tendency, variation and randomness of pattern.

What is the importance of run chart?

What type of chart is run chart?

A run chart is a line chart of data plotted over time. In other words, a run chart graphically depicts the process performance or data values in time order. Viewing data over time gives a more accurate conclusion rather than just summary statistics. A run chart is also known as trend chart or time series plot.

What does a run in a run chart mean?

Runs. A run is a series of five points on one side of the median. These points can be going up, down, or a combination of up and down, as long as they remain on one side of the median line.
