Sankey charts are a type of flowchart that are used to visualize and analyze data flows in a process. They are widely used in various industries, including manufacturing, logistics, and finance. This article will provide an overview of Sankey chart creation and its applications.

What are Sankey Charts?

Sankey charts are a type of flowchart that are named after William Sankey, an American statistician and industrial engineer. They are used to visualize and analyze data flows in a process. A Sankey chart consists of a central pathway, which represents the input to a process, and several branches, which represent the output of the process. The flow of data between the branches is represented by arrows, which are labeled with the amount of data flowing between them.

Sankey chart creation

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

1. Define the input and output of the process.
2. Identify the data flows between the input and output of the process.
3. Assign a direction to each data flow by adding an arrow from the input to the output.
4. Label each arrow with the amount of data flowing between the input and output.
5. Add labels and captions as needed.

There are several software programs that you can use to create Sankey charts, including Microsoft Excel, Lucidchart, and PySankey. These programs make it easy to create and customize Sankey charts to meet your specific needs.

Applications of Sankey Charts

Sankey charts are used in a variety of industries to help organizations understand and optimize data flows in their processes. Some of the specific applications of Sankey charts include:

1. Manufacturing: Sankey charts are used to visualize and analyze the movement of raw materials, work in process, and finished goods through a manufacturing process. They can be used to identify bottlenecks and inefficiencies in the process, and to develop improvements.
2. Logistics: Sankey charts are used to visualize and analyze the flow of goods through a logistics process. They can be used to identify inefficiencies and opportunities for improvement, and to develop transportation and distribution policies.
3. Finance: Sankey charts are used to visualize and analyze the flow of funds through a financial process. They can be used to identify opportunities for cost savings and revenue growth, and to develop financial policies.
4. Healthcare: Sankey charts are used to visualize and analyze the flow of patients through a healthcare process. They can be used to identify inefficiencies and opportunities for improvement, and to develop policies and procedures to improve patient outcomes.

Overall, Sankey charts are a useful tool for understanding and optimizing data flows in a process. They provide a visual, easy-to-understand representation of complex data flows, and can be customized to meet the specific needs of any industry or process. Whether you are a manufacturing manager, logistics specialist, financial analyst, or healthcare professional, Sankey charts can help you understand and improve your processes.
