Sankey charts are a powerful visualization tool that can be used to understand and optimize the flow of materials, information, and resources in any system. By mapping out the flow of different elements, you can gain a deeper understanding of where resources are wasted and where opportunities for improvement exist. In this article, we will explore how to create Sankey charts and the various applications of this powerful visualization technique.

What is a Sankey Chart?

A Sankey chart is a flowchart that is used to visualize the flow of materials, information, or resources from one node to another. It is named after British engineer and statistician Charles Sankey, who developed the technique in the early 20th century. A Sankey chart is particularly useful for identifying areas of waste and improving the efficiency of systems.

One of the key advantages of using a Sankey chart is that it allows you to easily identify the bottlenecks and inefficiencies in a system. By mapping out the flow of resources, you can see where they are being consumed and where there are opportunities for improvement. This can be particularly useful in complex systems, such as supply chain management or financial transactions.

Creation of a Sankey Chart

There are a few different ways to create a Sankey chart, but one of the most common methods involves using specialized software such as Visio or GanttPRO. These programs allow you to create a flowchart with multiple nodes and arrows, which can be used to represent the flow of resources.

To create a Sankey chart, you will need to follow these steps:

1. Choose the type of chart you want to create. Sankey charts are commonly used for visibility into resource flow and waste, but you can also use them for other types of visualization, such as process flow or decision flow.
2. Create the nodes in your chart. These will represent the various sources and destinations of resources.
3. Add the arrows between the nodes to represent the flow of resources. You can use arrows to indicate both the direction of the flow (e.g. input, output) and the type of resource being moved (e.g. material, information).
4. Customize the chart to meet your needs. You can add labels, shapes, or other visual elements to make the chart more informative and engaging.

Applications of Sankey Charts

Sankey charts are a versatile tool that can be used in a variety of contexts. Some common applications of Sankey charts include:

1. Supply chain management: By mapping out the flow of materials and resources in a supply chain, you can identify areas where waste or inefficiencies exist and make improvements to enhance the overall performance of the system.
2. Financial analysis: Sankey charts can be used to visualize the flow of funds through a financial system, helping you to identify areas where resources are being wasted or opportunities for optimization exist.
3. Process improvement: Sankey charts can be used to visualize the flow of tasks or steps in a process, allowing you to identify areas where resources are being consumed unnecessarily or where steps can be simplified or streamlined.
4. Environmental sustainability: By mapping out the flow of resources in a product or system, you can identify opportunities for reducing waste and improving the overall sustainability of the system.

In conclusion, Sankey charts are a powerful visualization tool that can be used to understand and optimize the flow of resources in any system. By mapping out the flow of materials, information, or resources, you can identify bottlenecks, inefficiencies, and opportunities for improvement. Whether you are managing a supply chain, conducting financial analysis, or improving a process, Sankey charts can provide valuable insights and help you to create more efficient and sustainable systems.
