Streamlining processes is a key aspect of improving efficiency and productivity in any organization. Sankey charts are a powerful tool for visualizing and understanding the flow of materials, information, or resources within a system. In this article, we’ll guide you through the process of creating a Sankey chart and explore some of the many applications to help streamline your organization’s processes.

What is a Sankey Chart?

A Sankey chart, also known as a Sankey flowchart, is a type of flowchart that is used to represent the flow of materials, information, or resources through a system. Unlike traditional flowcharts, which can be complex and difficult to interpret, Sankey charts use directional arrows to show the flow of materials or information, and use shapes to represent the different stages in the process.

Sankey charts are named after Rudolph Sankey, an English statistician who developed the method in the late 19th century. He used Sankey charts to visualize the flow of goods through a manufacturing process, and it quickly became a popular tool for analyzing and optimizing production systems.

How to Create a Sankey Chart

Creating a Sankey chart is a straightforward process that can be done using any spreadsheet software, such as Microsoft Excel or Google Sheets. Here’s a general overview of the steps involved:

1. Start by importing your data into a spreadsheet. This can be in the form of a table or a database query.
2. Add a pivot table to the spreadsheet to make it easier to summarize and analyze your data.
3. Create a new chart using the pivot table. Choose the “Sankey” chart option from the drop-down menu.
4. Customize the chart by adding any necessary shapes or labels, and adjusting the chart properties to fit your needs.
5. Export the chart to a format that is easy to share and use, such as a PDF or PowerPoint presentation.

Some Common Applications of Sankey Charts

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

1. Supply Chain Management: Sankey charts can be used to visualize the flow of goods through a supply chain, including supplier, distribution, and retail stages. This can help identify bottlenecks, optimize routes, and improve efficiency.
2. Material Management: Sankey charts can be used to visualize the flow of materials through a manufacturing process, including raw materials, intermediate products, and finished goods. This can help identify inefficiencies, optimize processes, and improve quality.
3. Financial Analysis: Sankey charts can be used to visualize the flow of money through a financial system, including income, expenses, and investments. This can help identify trends, optimize cash flow, and improve profitability.
4. Quality Improvement: Sankey charts can be used to visualize the flow of information or resources through a quality improvement process, including feedback loops, inspections, and corrective actions. This can help identify and eliminate defects, improve consistency, and enhance overall performance.
