Unleashing the Flow: Exploring Sankey Charts for Visible Process Improvement

Sankey charts are a powerful yet simple tool for visualizing and improving processes. They are particularly useful in identifying and addressing bottlenecks in processes, improving efficiency, and increasing transparency. In this article, we will explore the benefits of Sankey charts and how they can be used to unleash the flow of your organization.

Introduction to Sankey Charts

Sankey charts were originally developed by industrial engineer Frank A. Sankey in the early 20th century. They are graphical representations of the flow of materials or information through a process. Sankey charts use arrows to show the direction and rate of flow of materials or information, and the areas between the arrows represent the volume or value of the flow.

Each Sankey chart is made up of several components, including the input curve, the output curve, and the flow between the curves. The input curve represents the source of the material or information, while the output curve shows where it is delivered. The flow between the curves shows the movement of the material or information through the process.

Benefits of Sankey Charts

There are many benefits to using Sankey charts for process improvement:

1. Identifying Bottlenecks: Sankey charts can be used to identify bottlenecks in a process, which are areas where the flow of materials or information is reduced or slowed down. This is especially useful in complex or poorly understood processes.
2. Improving Efficiency: Sankey charts can be used to identify areas where the flow of materials or information can be improved, such as reducing wait times or optimizing production processes. This can result in increased efficiency and cost savings.
3. Enhancing Transparency: Sankey charts provide a visual representation of the flow of materials or information through a process, making it easier for everyone to understand and communicate.
4. Supporting Decision-Making: Sankey charts can be used to support decision-making by providing a clear and easy-to-understand visual representation of the process flow.

Applications of Sankey Charts

Sankey charts are used in a variety of industries and organizations to improve processes and increase efficiency. Some common applications of Sankey charts include:

1. Manufacturing: Sankey charts can be used to visualize and improve manufacturing processes, including production lines, supply chains, and supplier management.
2. Service Industries: Sankey charts can be used to visualize and improve service processes, including call centers, customer service, and technical support.
3. Supply Chain Management: Sankey charts can be used to visualize and improve supply chain processes, including procurement, inventory management, and logistics.
4. Project Management: Sankey charts can be used to visualize and improve project processes, including task management, resource allocation, and risk management.

Conclusion

Sankey charts are a powerful and simple tool for visualizing and improving processes. They can be used to identify and address bottlenecks, improve efficiency, and increase transparency in organizations of all sizes and industries. By using Sankey charts, organizations can unleash the flow of their processes and improve overall performance.
