Streamlining Your Ideas: The Power of Sankey Charts

Sankey charts are a type of flowchart that are used to visualize and analyze the flow of materials, energy, or information between different entities or stages. They were originally developed by Japanese scientist H.J. Sankey in the early 20th century for the purpose of analyzing the flow of materials in industrial processes.

Since then, Sankey charts have been used in a variety of fields, including engineering, ecology, finance, and marketing. They are a useful tool for identifying bottlenecks, optimizing processes, and identifying opportunities for improvement.

How to Create a Sankey Chart

To create a Sankey chart, you will need to gather data on the flow of materials, energy, or information between different entities or stages. This data can be obtained from a variety of sources, such as industry reports, government data, or internal records.

Once you have obtained the necessary data, you can use a software program such as Microsoft Excel or Python to create the chart. There are several steps involved in the process:

1. Identify the source and sink of the flow. This is typically the starting point and the endpoint of the flow, respectively.
2. Determine the flow rates for each step in the process.
3. Draw a line connecting the source to each step in the process, and draw arrows indicating the direction and flow rate of the flow.
4. Repeat step 3 for each step in the process, until you reach the sink.
5. Color code the lines and arrows to indicate the type of flow (e.g., material, energy, information).

Applications of Sankey Charts

Sankey charts are a useful tool for a wide range of applications. Some examples include:

• Process optimization: Sankey charts can be used to identify bottlenecks and inefficiencies in a process, and to identify opportunities for improvement. By visualizing the flow of materials, energy, or information, it is easier to identify areas where changes can be made to improve the overall efficiency of the process.
• Environmental analysis: Sankey charts can be used to analyze the flow of materials or energy between different stages of a production process, or between different regions of a natural ecosystem. This can help to identify areas where waste or pollution can be reduced, or where resources can be more efficiently used.
• Financial analysis: Sankey charts can be used to analyze the flow of funds or investments between different entities, or to identify areas where financial resources can be more effectively used.
• Marketing analysis: Sankey charts can be used to analyze the flow of customers or products between different stages of a marketing process, or to identify areas where customer satisfaction can be improved.

Conclusion

Sankey charts are a powerful tool for visualizing and analyzing the flow of materials, energy, or information between different entities or stages. They are a useful tool for process optimization, environmental analysis, financial analysis, and marketing analysis. By using a Sankey chart, you can gain insights into the efficiency and effectiveness of your operations, and identify opportunities for improvement.
