Sankey charts are a type of flowchart that are used to visualize the flow of materials, components, or information through a process or system. They are particularly useful for identifying bottlenecks, inefficiencies, and opportunities for improvement in a system. In this article, we will explore how to create Sankey charts and discuss various applications for this type of visual aid.
What is a Sankey Chart?
Sankey charts were invented by Carroll Sankey in the early 1930s and are named after him. They are a type of flowchart that represent the flow of materials or information through a system or process. Unlike traditional flowcharts, where the focus is on the movement of products or information from one place to another, Sankey charts focus on the efficiency and effectiveness of the process.
How to Create a Sankey Chart
There are several software programs that can be used to create Sankey charts. Some of the most popular include Microsoft Excel, Visio, and Lucidchart. These programs provide a range of tools and templates for designing Sankey charts, including shapes and connectors for representing the flow of materials or information.
One of the benefits of using a software program to create a Sankey chart is that it can be easily customized and adapted to suit the specific needs of the system being analyzed. Users can also import data from other sources, such as spreadsheets or databases, to build a more detailed and accurate chart.
Applications of Sankey Charts
Sankey charts are a powerful tool for visualizing flow and efficiency in a system. Some of the ways in which they can be used include:
- Process improvement: Sankey charts can be used to identify bottlenecks and inefficiencies in a process and develop strategies to improve it.
- Material flow analysis: Sankey charts can be used to visualize the flow of materials or components through a manufacturing process and identify areas where improvements can be made.
- Information flow: Sankey charts can be used to visualize the flow of information through an organization and identify opportunities for better communication and collaboration.
- Energy flow: Sankey charts can be used to visualize the flow of energy through a system or process and identify opportunities for reducing waste or increasing efficiency.
In addition to these applications, Sankey charts can also be used for strategic planning, team collaboration, and project management. They are a useful tool for anyone who needs to understand and optimize the flow of materials, information, or energy within a system.
Conclusion
Sankey charts are a powerful tool for visualizing flow and efficiency in a system. They can be used to identify bottlenecks, improve processes, and optimize the flow of materials, information, or energy. With a range of software programs available for creating Sankey charts, they are a flexible and adaptable visual aid that can be used in a wide range of settings. Whether you are a process manager, project manager, or simply looking to optimize the flow of materials or information within your organization, Sankey charts are a valuable resource for achieving these goals.
