The Throughput Chart

What Is It?

The throughput run chart visualizes the throughput of your team.

Before we move forward, this is the definition of throughput used across PaceMkr:

Throughput: The number of work items finished per unit of time.

Part 1 - Anatomy of the Chart

The throughput run chart is a 2-dimensional chart composed of an X and Y-axis.

The chart's X-axis contains the time on which we want to plot our data points. The X-axis of a throughput run chart always covers a period in the past.

The chart's Y-axis shows the throughput of the desired time.

Visually, a throughput run chart looks like the example below. The x-axis (Time) starts on January 31, 2022, and ends on March 21, 2022.

Our next step is to add a throughput on this chart. On February 28, 2022, there are four completed work items. In the image below, we can see how this conjunction is created on the chart.

Then, we plot the additional throughputs on the chart, as shown on the image below:

PaceMkr creates this chart for you from your historical data. Here is an example of a throughput run chart in PaceMkr:

Part 2 - Looking at a Throughput

By moving your cursor on a blue dot in the chart, a tooltip will pop up with a list of work items completed during this period.

The tooltip shows the time of the throughput, the number of completed items, and a list of those items. Clicking on any one of them will take you to the work item page in your Agile project management system.

Part 3 - Select Weeks

On the right-hand side of the chart, you will find a list of the weeks displayed on the x-axis . On some occasions, you might want to leave out some weeks.

For example, you might want to exclude throughputs during the holidays if your team is on vacation and nothing happens at this time. The red rectangle in the following example shows a throughput of 0 completed work items during the holiday period. You can see that the rolling average is impacted by those weeks.

By unchecking these weeks, the forecasting of your delivery dates reflect your reality. The image below shows what the throughput run chart looks like without those weeks. This way, the rolling average gives a better picture of your team's output.

Having abnormally high values is another reason to remove specific weeks. For example, the team cleaned up their board, closing more than 100 items in a particular week. These abnormally high values are shown in the image below by a red rectangle around the outlier. Not only will the resulting rolling average be skewed by this value, the forecasting of your delivery dates will be misleading.

By unchecking weeks that do not reflect your team throughput, you better forecast your delivery dates. The image below shows the same throughput chart without the outlier. Notice how the rolling average has a lower value and respects the actual throughput of the team. The forecasting will also be more precise without the outlier.

Parameters

At the bottom of the chart, you will find a list of settings to help you analyse your throughputs in different ways.

Daily or Weekly Throughput

You can toggle your throughput to be daily or weekly. Some teams prefer to look at their throughput each week, while other groups look at it everyday. It is usually a preference of how often they complete work items.

Weekends

When the daily throughput is selected, weekend throughputs are also shown on the chart and are included in the forecasting module of PaceMkr.

If your team doesn't work on the weekends, you can exclude them from your forecasting by turning them off. The outcome of this option is a more precise forecasting.

Rolling Average

If you do not work with rolling averages, you can turn this feature off. The green line on the chart will disappear. Some users also like to turn it off when they navigate the chart and don't want any interaction with the rolling average line.
