Streamlining your process is essential for improving efficiency and productivity. One powerful tool that can help you do this is Sankey charts. These charts are a type of flowchart that are particularly useful for visualizing and optimizing processes. In this article, we’ll explore how to create Sankey charts and the various applications of this visualization tool.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that is used to represent the flow of materials, energy, or information between different nodes or processes. It is named after its creator, Charles Sankey, who developed the chart in the early 20th century.

Sankey charts are particularly useful for visualizing processes that involve multiple steps and intermediaries. They are especially helpful for identifying opportunities for streamlining or optimizing processes.

How to Create a Sankey Chart

Creating a Sankey chart is relatively simple. There are several software programs that you can use to create a Sankey chart, including Microsoft Excel, Visio, and Lucidchart. Here’s an overview of the steps involved in creating a Sankey chart using Excel:

1. Open Microsoft Excel and create a new spreadsheet.
2. Insert a new table into the spreadsheet.
3. In cells A1 through A7, enter the different nodes or processes in the flow. For example, you might have nodes for receiving material, processing material, and shipping material.
4. In cells B1 through B7, enter the flow rate or volume for each process.
5. In cells C1 through C7, enter the direction of the flow. For example, arrows might point from the receiving area to the processing area, and from processing to shipping.
6. Select cells A1 through A7 and cells B1 through B7, and then go to Home > Auto Number. This will automatically assign a unique number to each cell in the table.
7. Go to Insert > Sankey Diagram. In the Sankey Diagram dialog box, select Process Flow and customize the chart as desired.
8. Click OK to insert the Sankey chart into the spreadsheet.

Applications of Sankey Charts

Sankey charts are incredibly versatile and can be used in a wide variety of applications. Some of the common uses of Sankey charts include:

1. Process Analysis: Sankey charts are particularly useful for analyzing processes that involve multiple steps and intermediaries. They allow you to visuallyize the flow of materials, energy, or information between different nodes or processes, making it easier to identify opportunities for streamlining or optimizing processes.
2. Supply Chain Management: Sankey charts are also commonly used in supply chain management to visualize the flow of goods or services from suppliers to customers. They can help you identify bottlenecks or inefficiencies in the supply chain and identify opportunities for improvement.
3. Environmental Management: Sankey charts can be used to visualize the flow of materials, energy, or waste in an environmental context. They can help you identify areas where waste can be reduced or reused and identify opportunities for recycling or composting.
4. Organizational Process Management: Sankey charts can be used to visualize the internal workings of an organization and identify areas where processes can be streamlined or optimized.

In conclusion, Sankey charts are a powerful tool for visualizing and optimizing processes. They are particularly useful for processes that involve multiple steps and intermediaries, such as supply chain management or environmental management. By using Sankey charts, you can gain a better understand of your processes and identify opportunities for improvement, leading to increased efficiency and productivity.
