Title: Streamlining Your Process: The Power of Sankey Charts

Sankey charts are a visual representation of the flow of materials, energy, or information in a system. They provide a powerful tool for understanding and optimizing the efficiency of processes. In this article, we will explore the creation and applications of Sankey charts, so you can learn how to streamline your own processes.

What are Sankey Charts?

Sankey charts were first introduced by engineer W.F. Sheaf in the late 19th century. He developed the chart as a means to represent the flow of materials through a system. Over time, the chart evolved to include information on energy and information flows as well.

The chart consists of a network of directed arcs that connect nodes, representing the different elements within the system. The arcs are oriented based on the direction of the flow and the magnitude of the flow. The chart provides a clear and concise view of the flow network, making it easy to identify the most efficient parts of the system and areas where improvements can be made.

Creation of Sankey Charts

To create a Sankey chart, you will need a few tools:

1. A flow analysis: A detailed flow analysis is needed to accurately represent the flow network. This may involve creating a flowchart, recording data from a process, or using simulation software.
2. A flowcharting software: There are several software programs that can be used to create Sankey charts. Some popular options include:
   • ProcessMap Professional
   • Sankey Flowchart
   • Microsoft Visio
3. A layout tool: A layout tool such as Adobe Illustrator or Inkscape can be used to create the chart.

Steps to create a Sankey chart:

1. Create a flowchart or record data from a process.
2. Import the flowchart or data into a flowcharting software.
3. Configure the software to create a Sankey chart.
4. Customize the chart as needed.
5. Layout the chart in a layout tool, such as Adobe Illustrator or Inkscape.
6. Export the chart.

Applications of Sankey Charts

Sankey charts provide valuable insights into the flow of materials, energy, or information in a system. They can be used in various applications, including:

1. Process improvement: Sankey charts help identify areas for improvement in a process. By visualizing the flow of materials, energy, or information, it is easy to identify bottlenecks and inefficiencies.
2. Supply chain management: Sankey charts can be used to analyze the flow of materials through a supply chain, helping companies identify areas where they can reduce waste and improve efficiency.
3. Environmental sustainability: Sankey charts can be used to analyze the flow of materials and energy through an organization and identify areas where resources can be optimized or waste reduced.
4. Project management: Sankey charts can be used to represent the flow of work through a project, helping project managers identify areas where resources can be improved or optimized.
5. Business strategy: Sankey charts can be used to represent the flow of information through an organization, helping companies identify areas where they can streamline communication and improve decision-making.

Conclusion

Sankey charts are a powerful tool for understanding and optimizing the efficiency of processes. By visualizing the flow of materials, energy, or information, Sankey charts provide valuable insights into areas for improvement and help companies make data-driven decisions. Creating a Sankey chart involves a flow analysis, flowcharting software, and a layout tool. The chart can be customized to fit the needs of the organization and used in various applications, including process improvement, supply chain management, environmental sustainability, project management, and business strategy.
