Streamlining Processes with Sankey Charts: A Visual Guide to Understanding Flow and Optimization

Sankey charts are a type of flowchart that are used to represent the flow of materials or energy between different nodes or processes. They are an excellent tool for visualizing and understanding the flow of resources in a system, and can be used to identify areas for improvement and optimization. In this article, we will explore the basics of Sankey chart creation, as well as some practical applications of this powerful visualization tool.

How to Create a Sankey Chart

Sankey charts can be created using a variety of software tools, including Microsoft Excel, Lucidchart, and Smartsheet. Here is a step-by-step guide to creating a Sankey chart using Microsoft Excel:

1. Open Microsoft Excel and create a new workbook.
2. Enter your data into the Excel cells. The data should include the names of the nodes or processes, as well as the flow rates or other relevant information.
3. Highlight the data in the Excel cells.
4. Click on the “Insert” menu and select “Sankey Flowchart.” This will create a new Sankey chart in the worksheet.
5. Customize the Sankey chart by adjusting the chart properties, such as the width and height of the chart, the colors used to represent the nodes, and the orientation of the chart.
6. Save the chart to your desired location and format it as needed.

Applications of Sankey Charts

Sankey charts have a wide range of applications, including:

1. Flow analysis: Sankey charts are particularly useful for visualizing the flow of materials or energy between different nodes or processes. This can help identify areas where there are bottlenecks or inefficiencies in the system.
2. Process optimization: By analyzing the flow of resources in a system using a Sankey chart, it is possible to identify areas for improvement and optimization. For example, you may be able to identify opportunities to reduce waste or improve the efficiency of certain processes.
3. Supply chain management: Sankey charts can be used to visualize the flow of goods or materials through a supply chain, helping to identify opportunities to optimize the flow of goods and reduce costs.
4. Environmental analysis: Sankey charts can be used to visualize the flow of materials or energy through an environmental system, such as a recycling facility or waste treatment plant. This can help identify areas where there are opportunities to reduce waste or improve the efficiency of the system.

Conclusion

Sankey charts are a powerful visualization tool that can be used to understand and optimize the flow of resources in a system. By creating a Sankey chart, it is possible to identify areas for improvement and optimization, leading to more efficient and effective processes. Whether you are a process manager, supply chain professional, or environmental analyst, a Sankey chart can provide valuable insights and help you streamline your processes.
