The Art of Streamlining: A Guide to Sankey Chart Mastery

Sankey charts are a powerful and versatile tool for visualizing the flow of a process or system. They are particularly useful for showing how inputs and outputs are transformed and converted as they move through a system. In this article, we will explore the art of creating and mastering Sankey charts.

Sankey Chart Basics

A Sankey chart is a type of flowchart that is used to show the flow of materials, energy, or information through a system. It is named after the British engineer, Charles Sankey, who developed the technique in the 1920s. Sankey charts are particularly useful for showing how inputs and outputs are transformed and converted as they move through a system, helping to identify opportunities for streamlining and waste reduction.

Sankey Chart Creation

To create a Sankey chart, you will need to gather information about the flow of your system. This typically involves identifying the different inputs, outputs, and processes that make up your system. You will then need to create a diagram showing the flow of materials, energy, or information through each process, using arrows to show the direction and magnitude of the flow.

The diagram should also include a set of nodes, which represent the different input and output points in the system, and a set of links, which represent the flow of materials, energy, or information between the nodes. You will typically want to label each node and link with a descriptive text to help understand the flow of the system.

Sankey Chart Applications

Sankey charts have a wide range of applications, including:

1. Process flow analysis: Sankey charts are particularly useful for visualizing the flow of materials or information through a process, helping to identify opportunities for improvement and optimization.
2. Waste reduction: Sankey charts can be used to show the flow of materials or energy through a system, highlighting areas where waste or energy is generated or consumed. This can help identify opportunities for reducing waste and improving energy efficiency.
3. Supply chain management: Sankey charts can be used to show the flow of materials or information through a supply chain, helping to identify bottlenecks and opportunities for improvement.
4. Environmental impact analysis: Sankey charts can be used to show the flow of materials, energy, or information through a system, highlighting areas where changes can be made to reduce environmental impact.

Sankey Chart Mastery

To master the art of Sankey chart creation and application, it is important to have a solid understanding of the underlying principles of the chart. This includes the different types of flows that can be represented, the symbols and notation used in the chart, and the best practices for creating effective charts.

A good starting point for learning about Sankey charts is to review the original work by Charles Sankey and other experts in the field. This will provide a solid foundation for understanding the technical aspects of the chart. You may also want to consider taking a course or workshop on Sankey chart creation and mastery to receive hands-on training and examples.

In conclusion, Sankey charts are a powerful and versatile tool for visualizing the flow of a process or system. With a little practice and mastery, you can use Sankey charts to identify opportunities for streamlining and improvement, and to drive positive change in organizations and systems alike.
