Unleashing the Power of Sankey Charts: Navigating Data Flow and Optimizing Processes

Sankey charts are a powerful and visually appealing tool for understanding data flow and identifying opportunities for process optimization. They were originally developed in the 1960s by Dr. Charles Sankey as a way to visualize the flow of materials and resources between different entities. Today, they are widely used in a variety of industries to analyze data, identify trends, and improve processes. In this article, we will explore the basics of Sankey chart creation and demonstrate the many applications of this powerful visualization tool.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that uses circles and arrows to represent the flow of materials or information between different entities. The chart is named after Dr. Charles Sankey, who developed the technique in the 1960s while working at the United States Department of Agriculture. Sankey charts are particularly useful for visualizing complex data flows and identifying opportunities for process improvement.

Basics of Sankey Chart Creation

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

1. Identify the entities being analyzed: The first step in creating a Sankey chart is to identify the entities that are involved in the data flow being analyzed. These could be products, customers, suppliers, or any other entities that are relevant to the analysis.
2. Gather data on the flow of materials or information: Once you have identified the entities involved in the data flow, you will need to gather data on the flow of materials or information between them. This data could be in the form of a table or a spreadsheet.
3. Set up the Sankey chart: To create the chart, you will need to set up the circles and arrows that represent the flow of materials or information between the entities. The circles represent the entities, and the arrows represent the flow of materials or information.
4. Label the chart: Each circle and arrow should be labeled with the name of the entity and the direction of the flow. This will help to make the chart easy to understand and interpret.

Applications of Sankey Charts

Sankey charts can be used in a variety of industries to analyze data, identify trends, and improve processes. Some of the key applications of Sankey charts include:

1. Supply chain management: Sankey charts can be used to visualize the flow of materials or information through a supply chain, highlighting areas where bottlenecks or inefficiencies may exist. This can help to identify opportunities for process improvement and cost savings.
2. Pricing and revenue analysis: Sankey charts can be used to analyze the flow of revenue or sales between different products or services. This can help companies to identify opportunities for cross-selling or upselling.
3. Customer analysis: Sankey charts can be used to visualize the flow of data or information between different customer segments. This can help companies to identify patterns and trends that may be useful for developing targeted marketing campaigns or improving customer service.

Conclusion

Sankey charts are a powerful and versatile tool for visualizing data flow and identifying opportunities for process optimization. They are particularly useful in industries such as supply chain management, pricing and revenue analysis, and customer analysis. By following the steps outlined in this article, you can create your own Sankey chart and unlock the full potential of this powerful visualization tool.
