Streamlining processes is crucial to business success, as it enables organizations to operate more efficiently and optimize their resources. Sankey charts are a powerful tool for visualizing and understanding the flow of materials, information, and other resources in a system. In this article, we will delve into the basics of creating Sankey charts, their applications, and how to use them for process optimization.

What is a Sankey Chart?

A Sankey chart, also known as a Sankey flowchart, is a type of visualization tool used to display the flow of materials, information, or energy between different nodes (or areas) in a system. It was originally developed by Carl Sankey in the 1920s as a tool for analyzing and optimizing industrial processes.

Sankey charts are particularly useful for identifying bottlenecks, optimizing resource usage, and visualizing the overall flow of a system. They can be used to track the movement of materials, energy, or information through a supply chain, a manufacturing process, or any other type of system.

Creating a Sankey Chart

There are several software programs available for creating Sankey charts, including Microsoft Visio, Lucidchart, and SmartDraw. However, the process of creating a Sankey chart is relatively simple and straightforward. Here are the basic steps:

1. Determine the nodes: Identify the different areas or entities within the system that will be included in the chart. These may include suppliers, manufacturers, distributors, customers, or any other relevant areas.
2. Add relationships: Next, add arrows between the nodes to show the flow of materials, information, or energy between them. These arrows can be colored and labeled to differentiate between different types of flow.
3. Customize the chart: Finally, you can customize the chart to your specific needs by adding shapes, text, and other visual elements. You can also adjust the layout and formatting of the chart to make it easier to read and understand.

Applications of Sankey Charts

Sankey charts are a versatile tool that can be used in a wide range of industries and applications. Some of the common uses include:

1. Supply chain management: Sankey charts can be used to visualize the flow of materials and components through a supply chain, helping to identify bottlenecks and opportunities for process improvement.
2. Process optimization: Sankey charts can be used to analyze and optimize a manufacturing process, identifying areas where resources are being used inefficiently and suggesting improvements.
3. Energy management: Sankey charts can be used to visualize the flow of energy through a system, helping to identify opportunities for energy efficiency and reducing waste.
4. Financial analysis: Sankey charts can be used to visualize the flow of money or other financial resources through a business, helping to identify areas where resources are being underused or overused.
5. Customer service: Sankey charts can be used to visualize the flow of customer requests and support through a business, helping to identify areas where customer satisfaction can be improved.

Conclusion

Sankey charts are a powerful tool for visualizing and understanding the flow of materials, information, or energy in a system. By using a Sankey chart, organizations can identify bottlenecks, optimize resource usage, and improve the overall efficiency of their processes. With the right software program and a little bit of creativity, creating a Sankey chart is a simple and effective way to streamline processes and achieve business success.
