Streamlining Your Process: The Ultimate Guide to Sankey Charts

Sankey charts are a type of flow diagram that are used to visually represent the flow of materials, energy, or information through a system. They are particularly useful for identifying bottlenecks, optimizing processes, and identifying opportunities for improvement. In this guide, we will explore how to create and apply Sankey charts to streamline your processes.

The Basics of Sankey Charts

Sankey charts are named after Rudolph Sankey, an English economist who developed the chart in the early 20th century. The chart consists of a set of interconnected circles, with arrows connecting the circles to indicate the flow of materials, energy, or information. The circles represent the inputs and outputs of a process, and the arrows indicate the direction and quantity of the flow.

There are two main types of Sankey charts: directed and undirected. Directed Sankey charts show the flow of materials or information from one input to one output, while undirected Sankey charts show the flow of materials or information through a cycle.

Applications of Sankey Charts

Sankey charts are used in a variety of fields, including engineering, chemistry, economics, and healthcare. Some common applications of Sankey charts include:

1. Identifying bottlenecks: Sankey charts can be used to identify bottlenecks in a process, which are the areas where the flow of materials, energy, or information is reduced. By identifying these bottlenecks, you can take steps to improve the efficiency of the process.
2. Optimizing processes: Sankey charts can be used to identify opportunities for process improvement, such as reducing waste or increasing efficiency. By analyzing the flow of materials or information through a process, you can identify areas where changes can be made to improve efficiency.
3. Tracing the origin and destination of materials or information: Sankey charts can be used to trace the origin and destination of materials or information in a system. This can be useful for understanding the flow of materials or information and identifying opportunities for improvement.

How to Create Sankey Charts

There are several software programs and online tools that you can use to create Sankey charts, including Microsoft Excel, Lucidchart, and Visio. These programs provide a range of templates and tools that make it easy to create Sankey charts.

To create a Sankey chart, follow these steps:

1. Choose a software program or tool that supports Sankey charts.
2. Create a new chart or open an existing one.
3. Add circles to the chart to represent the inputs and outputs of your process.
4. Add arrows to the chart to represent the flow of materials, energy, or information.
5. Customize the chart to match your process and your needs.

Applying Sankey Charts to Streamline Your Processes

Once you have created a Sankey chart, you can use it to streamline your processes in several ways, including:

1. Identifying bottlenecks: Use Sankey charts to identify areas where the flow of materials, energy, or information is reduced. This can help you identify opportunities for process improvement.
2. Optimizing processes: Use Sankey charts to identify areas where changes can be made to improve efficiency. This can help you reduce waste, improve productivity, and increase profitability.
3. Tracing the origin and destination of materials or information: Use Sankey charts to trace the flow of materials or information through a process. This can help you understand the origin and destination of materials or information and identify opportunities for improvement.
4. Communicating process flows to others: Use Sankey charts to communicate the flow of materials or information through a process to stakeholders, such as team members or customers.

Conclusion

Sankey charts are a powerful tool for streamlining processes and identifying opportunities for improvement. By using Sankey charts, you can improve the efficiency of your processes, reduce waste, and increase profitability. So
