Sankey charts are a type of flowchart that can be used to visualize the flow of materials, information, or ideas between different entities or processes. They are commonly used in process mapping, inventory management, and supply chain analysis, among other fields. In this article, we will explore how to create and apply Sankey charts to streamline processes and improve efficiency.

Creating a Sankey Chart

Sankey charts can be created using a variety of software tools, such as Microsoft Visio, Lucidchart, or SmartDraw. These tools typically offer a drag-and-drop interface that allows you to create the chart by simply adding and connecting shapes representing the various entities or processes involved in the flow.

To create a Sankey chart, follow these steps:

1. Open the software tool of your choice and create a new chart.
2. Add the start and end points of the flow by drawing two shape representing the source and destination of the flow.
3. Drag the entities or processes involved in the flow to the appropriate shapes, and connect them with arrows to indicate the direction and type of flow.
4. Customize the chart as desired, such as adding notes or change the color to represent different stages of the flow.

Applications of Sankey Charts

Sankey charts are an effective tool for streamlining processes and improving efficiency, and can be used in a variety of fields and industries. Some of the common applications of Sankey charts include:

1. Process Mapping: Sankey charts can be used to visually map out the steps involved in a process, identify bottlenecks and areas for improvement, and help identify new opportunities for process optimization.
2. Inventory Management: Sankey charts can be used to visualize the flow of materials between different inventory locations or suppliers, and help identify areas for process improvement, such as reducing lead times or increasing efficiency in the ordering process.
3. Supply Chain Analysis: Sankey charts can be used to analyze the flow of materials or information between different members of a supply chain, and help identify areas for process improvement, such as reducing lead times, improving communication, or optimizing the flow of materials.
4. Environmental Management: Sankey charts can be used to visualize the flow of materials or waste between different stages of the production process, and help identify opportunities for reducing waste, improving energy efficiency, or increasing the circularity of the production process.

In conclusion, Sankey charts are a useful visualization tool for process mapping, inventory management, supply chain analysis, and environmental management, among other fields. By using a Sankey chart, you can identify areas for process improvement, and improve the overall efficiency and effectiveness of your processes.
