Sankey charts are a powerful tool for visualizing complex processes. They allow users to see how different components of a process interact with each other, and to identify potential bottlenecks and areas for improvement. In this article, we will discuss how to create Sankey charts, and explore some of the many ways in which they can be used to enhance process visualization.

What is a Sankey chart?

Sankey charts are a type of flowchart that use arrows to represent the flow of materials or information between different components of a process. Unlike traditional flowcharts, which use streams and nodes to represent the various stages of a process, Sankey charts use lines and circles to represent the different parts of the process.

Sankey charts are especially useful for visualizing processes that involve multiple intermediaries, or that have complex dependencies between different steps. They can be used to map out the flow of materials or information through a process, identify where energy or resources are lost or wasted, and track the progress of a process over time.

How to create a Sankey chart

Creating a Sankey chart is relatively simple. To get started, you will need to have a process that you would like to visualize using a Sankey chart. This can be a complex process, or a simple series of steps.

Once you have your process, you can begin to create your Sankey chart by adding the different components of the process to the chart. Use lines and circles to represent the different steps and intermediaries in the process. Connect the circles and lines to show the flow of materials or information between the different components.

To make the chart even more informative, you can add additional information such as the amount of materials or information flowing between each step, or the time it takes to move from one step to the next. You can also use color or other visual cues to highlight specific areas of the chart, or to show how the process is changing over time.

Applications of Sankey charts

There are many ways in which Sankey charts can be used to improve process visualization. Some of the most common applications include:

• Identifying bottlenecks: Sankey charts can be used to easily identify where a process is slowing down or where resources are being wasted. By highlighting these areas, you can take steps to improve the efficiency of the process.
• Tracking progress: Sankey charts can be used to track a process over time, to see how it is evolving and improving. This can be useful for monitoring the efficiency of a process, or for identifying trends and patterns.
• Improving resource allocation: By analyzing the flow of materials or information between different components of a process, you can identify where resources are being used inefficiently, and where they could be better allocated.
• Designing process improvement: Sankey charts can be used to design and implement process improvements. For example, you can use the chart to identify areas where a process could be streamlined, or where it could be made more efficient.

Conclusion

Sankey charts are an powerful tool for visualizing complex processes. They allow users to see how different components of a process interact with each other, and to identify potential bottlenecks and areas for improvement. By creating a Sankey chart, you can easily see how a process is flowing, and improve its efficiency and effectiveness. So, try it today!
