Sankey charts are a powerful and visually appealing way to represent the flow of a process, highlighting the strengths and weaknesses of different steps and identifying opportunities for improvement. In this article, we will take a close look at the creation and applications of Sankey charts, so you can harness their full potential for process improvement.

Introduction to Sankey Charts

Sankey charts, also known as flowcharts, are a type of flow diagram that use arrows to show the direction and rate of flow of materials, information, or energy through a system. They are named after the Dutch engineer Louis Pasteur Sankey, who developed the technique in the 19th century.

Sankey charts are widely used in process improvement, design, and analysis. They are particularly useful for visualizing the flow of a process, identifying bottlenecks, and prioritizing areas for improvement.

The basics of Sankey chart creation

Sankey charts are created using specialized software such as Microsoft Visio, Lucidchart, or SmartDraw. These tools provide a range of features and templates to help you create your chart with ease. Here is a step-by-step guide to creating a Sankey chart:

1. Open your charting software and create a new chart by clicking on “File” and selecting “New.”
2. Choose “Sankey chart” from the chart types available, or search for it using the search bar.
3. Create your chart by adding shapes and connecting them with arrows to represent the flow of your process.
4. Customize your chart by adding labels, colors, and other details to enhance its clarity and impact.
5. Save and export your chart as needed.

Applications of Sankey Charts

Sankey charts are widely used in various fields, including process improvement, project management, and supply chain management. Here are some examples of how Sankey charts can be applied:

1. Process improvement: Sankey charts are a powerful tool for identifying bottlenecks and inefficiencies in a process. By visualizing the flow of materials, information, or energy, you can quickly see where there are opportunities for improvement and prioritize actions accordingly.
2. Project management: Sankey charts are a useful tool for visualizing the progress of a project and identifying areas where tasks are falling behind schedule or where resources are being overused.
3. Supply chain management: Sankey charts can be used to analyze and optimize the flow of goods and services throughout a supply chain. By identifying and addressing bottlenecks, you can improve the efficiency and effectiveness of your supply chain.
4. Quality improvement: Sankey charts can be used to map out the process for creating a product or service, highlighting areas where quality can be improved and identifying potential sources of defects.

Conclusion

In conclusion, Sankey charts are a powerful and visually appealing tool for process improvement. They are widely used in various fields, including process improvement, project management, and supply chain management. By creating and applying Sankey charts, you can quickly and effectively identify areas for improvement and prioritize actions to optimize your processes.
