Flowcharting the Circulation: Mastering Sankey Charts for Process Visualization

Sankey charts are a powerful and flexible flowcharting tool that has become increasingly popular in recent years due to their ability to visualize the flow of materials, energy, and information in a process. With their ability to represent the flow of goods, services, and resources between different nodes, Sankey charts are an ideal tool for process optimization, waste reduction, and sustainability planning. In this article, we will explore the basics of Sankey chart creation and their applications in various fields.

Understanding Sankey Charts

Sankey charts are a type of flowchart created using a specialized set of symbols and arrows to represent the flow of materials, energy, and information in a process. They are named after the Dutch engineer Gerardus Sankey, who developed the technique in the early 1930s as a means for visualizing the flow of materials in industrial processes.

The basic structure of a Sankey chart consists of three main parts: a source, a set of nodes representing the different stages of the process, and a set of directed arrows connecting the nodes. The arrows represent the flow of materials, energy, or information from the source to the nodes and from the nodes to the sink.

Sankey charts can be used to visualize a wide variety of processes, from manufacturing and logistics to environmental systems and financial flows. They are particularly useful for identifying bottlenecks, inefficiencies, and opportunities for improvement in a process.

Creating Sankey Charts

Creating a Sankey chart is a relatively simple process that can be done using a variety of software tools, such as Microsoft Excel, Google Sheets, or specialized Sankey charting software. The basic steps for creating a Sankey chart are as follows:

  1. Determine the source and sink of the process that you want to visualize. The source is the input or incoming material, and the sink is the output or outgoing material.
  2. Identify the different stages or nodes in the process, and assign a label or description to each one.
  3. Draw arrows between the nodes to represent the flow of materials, energy, or information from the source to the nodes and from the nodes to the sink.
  4. Customize the appearance of the chart, such as adding colors, lines, or tags to the nodes and arrows.

Applications of Sankey Charts

Sankey charts have a wide range of applications in various fields, including manufacturing, logistics, environmental systems, and finance. Some of the common applications of Sankey charts include:

  1. Process optimization: Sankey charts can be used to identify and eliminate bottlenecks and improve the efficiency of a process. By visualizing the flow of materials, energy, and information, it is possible to identify opportunities for process optimization and waste reduction.
  2. Sustainability planning: Sankey charts can be used to visualize the flow of materials, energy, and resources in a process, allowing stakeholders to identify opportunities for reducing waste, conserving resources, and improving the sustainability of the process.
  3. Product life cycle analysis: Sankey charts can be used to visualize the flow of materials and resources through the entire life cycle of a product, allowing stakeholders to identify opportunities for reducing waste and improving the sustainability of the product.
  4. Financial flows: Sankey charts can be used to visualize the flow of money and other financial resources between different entities, allowing stakeholders to identify opportunities for improving the efficiency of financial processes and reducing fraud and waste.

Conclusion

Sankey charts are a powerful and flexible flowcharting tool that has become increasingly popular in recent years for visualizing the flow of materials, energy, and information in a process. With their ability to represent the flow of goods, services, and resources between different nodes, Sankey charts are an ideal tool for process optimization, waste reduction, and sustainability planning. By understanding the basics of Sankey chart creation and their applications in various fields, you can begin to unlock the potential of this powerful visualization tool.
