Unleashing the Power of Sankey Charts for Process Improvement

Sankey charts are a type of visualization tool that is widely used to represent the flow of materials, energy, or information between different nodes in a system. They were originally developed in the 19th century by the British engineer and physicist Charles Sankey as a way to study the energy efficiency of industrial processes. Today, Sankey charts are used in a variety of fields, including process improvement, project management, and sustainability. In this article, we’ll explore how Sankey charts can be used to analyze and improve processes, as well as some best practices for creating effective charts.

Understanding Sankey Charts

Sankey charts are essentially flow diagrams that show the direction and flow of materials, energy, or information between different nodes in a system. Each node in the chart represents a process or activity, and the arrows between nodes show the flow of materials or energy through that process. Sankey charts are useful for visualizing the efficiency of a process and identifying areas where improvements can be made.

One of the key benefits of Sankey charts is that they make it easy to identify bottlenecks and inefficiencies in a process. For example, if a process has a number of intermediary steps that take a long time to complete, it may indicate that those steps are in need of optimization. Additionally, Sankey charts can be used to compare different processes or systems, which can be useful for process improvement or benchmarking.

Applications of Sankey Charts

Sankey charts have a wide range of applications, including:

1. Process Improvement: One of the main benefits of Sankey charts is that they can be used to visualize and analyze a process, identify areas for improvement, and develop strategies for optimization. By mapping out the flow of materials or energy through a process, it is possible to identify bottlenecks and areas where waste or excess can be reduced.
2. Project Management: Sankey charts can also be used to manage projects by visualizing the flow of work between different tasks or milestones. This can be useful for identifying dependencies, identifying risks, and developing project plans.
3. Sustainability: Sankey charts can be used to visualize the flow of materials, energy, or information between different nodes in a system, making it possible to identify areas where sustainability can be improved. For example, a Sankey chart for a manufacturing facility might highlight areas where raw materials can be sourced more sustainably or where waste can be reduced.
4. Supply Chain Management: Sankey charts can be used to visualize and analyze the flow of materials or information between different nodes in a supply chain. This can help identify areas where improvements can be made to reduce costs or improve efficiency.

Creating Effective Sankey Charts

To create effective Sankey charts, there are a few key principles to keep in mind:

1. Start with a clear understanding of the process being visualized: Before you begin creating a Sankey chart, it is important to have a clear understanding of the process you are trying to visualize. This may involve conducting research or interviewing stakeholders to gather information about the steps involved in the process.
2. Identify the nodes in the chart: Each node in the chart should represent a process or activity. This may involve breaking down larger processes into smaller, more manageable steps.
3. Use arrows to show the direction of flow: Arrows should be used to show the direction and flow of materials or energy through each node in the chart. These arrows should be labeled to make it easy to understand the flow direction.
4. Use colors or symbols to differentiate between nodes: Colors or symbols can be used to differentiate between nodes in the chart, making it easier to understand the flow of materials or energy.
5. Make the chart easy to read and understand: It is important to create a chart that is easy to read and understand, without overwhelming the viewer with too much information. This may involve using simple graphics, labeling arrows clearly, and avoiding clutter.

In conclusion, Sankey charts are a powerful visualization tool that can be used to improve processes, manage projects, and promote sustainability. By understanding the principles of Sankey chart creation and applying them to your own processes and projects, you can unleash the power of these charts to drive improvement and success.
