A Sankey chart is a type of flowchart that is used to visualize a process or a system. It is named after its creator, Harry Sankey, who first introduced the chart in the 1920s. Sankey charts are particularly useful in identifying opportunities and areas for improvement in a process. In this article, we will explore the creation of Sankey charts and their applications in business and other fields.

How to Create a Sankey Chart

One of the most impressive things about Sankey charts is that they can be created using a simple spreadsheet program, such as Microsoft Excel. Here are the steps to create a Sankey chart using Excel:

1. Open a new Excel spreadsheet and select the data that you will be using to create the chart.
2. Go to the “Insert” tab in the ribbon menu at the top of the screen.

Applications of Sankey Charts

Sankey charts are used in a variety of applications, including process improvement, project management, and supply chain analysis. Here are some examples of how Sankey charts can be used in different fields:

1. Process Improvement: Sankey charts are particularly useful in highlighting areas where a process could be improved. By visualizing the flow of materials or information through a process, Sankey charts can help identify bottlenecks, inefficiencies, and opportunities for improvement.
2. Project Management: Sankey charts can be used to visualize the progress of a project over time. By connecting different stages of the project, such as planning, design, and implementation, Sankey charts can help project managers track their progress and identify any areas where delays or issues are occurring.
3. Supply Chain Analysis: Sankey charts can be used to visualize the flow of materials or information through a supply chain. By connecting different stages of the supply chain, such as procurement, production, and distribution, Sankey charts can help identify opportunities for improvement and areas where issues may be occurring.
4. Environmental Sustainability: Sankey charts can be used to visualize the flow of materials or energy through an industrial process or facility. By connecting different stages of the process, such as raw material acquisition, production, and waste disposal, Sankey charts can help identify opportunities for reducing waste and increasing efficiency.

In conclusion, Sankey charts are a useful tool for visualizing processes and identifying opportunities for improvement. They can be easily created using a spreadsheet program and have a wide range of applications in business and other fields.
