Unleashing the Power of Change: Exploring Sankey Charts for Process Visualization

Change is the only constant in life, and organizations are no exception. Processes evolve over time, with changes to technology, workflow, and customer expectations constantly shaping the way businesses operate. Visualizing these changes can help organizations gain a better understanding of their processes and identify areas that can be improved. Sankey charts are a powerful visualization tool that can be used to explore process flows and identify opportunities for improvement.

What is a Sankey Chart?

A Sankey chart, also known as a directed flowchart or network flowchart, is a type of flowchart that highlights the flow of materials, information, or energy between different nodes or process steps. Unlike traditional flowcharts, which include arrows to represent the flow of materials or information, Sankey charts include directed arrows to show the direction and magnitude of the flow. These directed arrows represent the amount of material or information flowing between each node, with the magnitude of the arrow indicating the size or quantity of the flow.

Sankey charts can be used to visualize complex process flows and identify areas where improvements can be made. For example, a Sankey chart of a manufacturing process might highlight bottlenecks in the production line, or areas where materials can be easily reused or recycled.

How to Create a Sankey Chart

Creating a Sankey chart can be done using a variety of software tools, including Microsoft Excel, Visio, and Lucidchart. These tools provide a range of templates and shapes for creating the chart, as well as options for customizing the chart’s appearance and layout.

To create a Sankey chart in Excel, users can follow these steps:

1. Enter the process steps into the Excel sheet as columns.
2. Insert a rectangle for each step using the “Shapes” tab.
3. Connect the rectangles using arrows with a fill color that represents the amount of flow.
4. Customize the chart as desired, such as changing the arrow color to indicate the direction of the flow.

Visio, on the other hand, provides a user-friendly interface for creating Sankey charts, with a range of shapes and templates available for easy customization. To create a Sankey chart in Visio, users can follow these steps:

1. Insert a rectangle for each step in the process flow.
2. Connect the rectangles with arrows to represent the flow of materials or information.
3. customize the chart as desired, such as changing the arrow color to represent the direction of the flow.

Applications of Sankey Charts

Sankey charts can be used to visualize and understand complex process flows in a variety of industries. Some industries that can benefit from Sankey charts include manufacturing, logistics, finance, and healthcare.

In manufacturing, a Sankey chart can be used to visualize the flow of materials through a production line, identifying areas where bottlenecks or inefficiencies exist. This can help manufacturers make improvements to increase efficiency and reduce costs.

In healthcare, a Sankey chart can be used to visualize the flow of patient information through a hospital or clinic, highlighting areas where information may be lost or misinterpreted. This can help healthcare providers identify areas where improvements can be made to improve patient care and reduce errors.

In finance, a Sankey chart can be used to visualize the flow of funds through an investment portfolio, identifying areas where investments may be underperforming or where risk may be集中. This can help financial advisors make informed decisions about investment strategies and risk management.

Conclusion

Sankey charts are a powerful visualization tool that can be used to explore process flows and identify areas for improvement. With their ability to highlight flow direction and magnitude, Sankey charts provide a detailed and actionable view of complex processes. Whether used in manufacturing, healthcare, finance, or any other industry, Sankey charts can help organizations make informed decisions about process improvement and optimize their operations.
