Sankey charts are a type of flowchart that are used to visually represent the flow of materials, information, or ideas within a system or process. They are particularly useful for identifying bottlenecks, areas of inefficiency, and opportunities for improvement. In this article, we will explore the power of Sankey charts and how to use them to optimize efficiency and productivity.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that is named after its creator, Karl Sankey. It is a type of network diagram that visualizes the flow of materials, energy, or information through a system. The chart consists of a rectangular box representing the source or starting point in the system, and a series of arrows or lines that represent the flow of the material or information through the system.

Each arrow or line in the chart is labeled with the amount or rate of flow, and can be directed to one or more downstream boxes or nodes. The chart also includes a set of input and output numbers that represent the total amount of flow in and out of the system.

Benefits of Using Sankey Charts

There are several benefits to using Sankey charts to visualize and optimize a system or process:

1. Identifying bottlenecks and areas of inefficiency: Sankey charts help identify bottlenecks and areas of inefficiency in a system. By visualizing the flow of materials or information, it is easy to see where the system may be struggling or experiencing delays.
2. Improving efficiency and productivity: Sankey charts can help improve efficiency and productivity by highlighting areas where the system can be optimized. For example, by identifying a bottleneck in the system, you can take steps to remove it or streamline the process, which can lead to increased productivity and efficiency.
3. Identifying opportunities for improvement: Sankey charts can also help identify opportunities for improvement in a system. For example, by analyzing the flow of materials or information through the system, you may identify ways to reduce waste, improve the efficiency of a process, or streamline the overall system.
4. Enhancing communication and collaboration: Sankey charts are a visual tool that can enhance communication and collaboration among team members and stakeholders. By sharing a visual representation of the system or process, it can help everyone understand the flow of materials or information and work together to identify areas for improvement.

How to Create a Sankey Chart

Creating a Sankey chart is relatively simple, and can be done using a variety of tools and software. Here is a step-by-step guide on how to create a Sankey chart:

1. Identify the source and destination of the flow: Decide on the starting and ending points of the flow that you want to visualize in the system.
2. Choose the type of chart: Decide whether you want to create a flowchart that represents materials, energy, or information. This will help determine the type of chart you need to create and the specific data that needs to be included.
3. Gather and organize the data: Gather all the data that you need to include in the chart, and organize it in a way that makes sense. This may involve categorizing the data, calculating the rate of flow for each arrow or line, and formatting the chart in a way that makes it easy to read and understand.
4. Create the chart: Use the chosen software or tool to create the Sankey chart. There are many options available for creating Sankey charts, including online tools likeDraw.io or ProcessOn, and desktop software likeSmartDraw or Lucidchart.
5. Review and refine: Review the chart to make sure it accurately represents the flow of materials or information through the system, and refine the chart as necessary.

Conclusion

Sankey charts are a powerful tool for visualizing flow and optimizing efficiency in a system or process. They are a simple and effective way to identify bottlenecks, areas of inefficiency, and opportunities for improvement, and can be used to enhance communication and collaboration among team members and stakeholders. By following the steps outlined in this article, you can create a Sankey chart to gain a better understanding of your system or process and take steps to optimize it for improved efficiency and productivity.
