Sankey charts are a type of flowchart that are used to visualize the flow of materials, energy, or information through a system. They are particularly useful for identifying bottlenecks, inefficiencies, and opportunities for improvement. In this article, we will explore how to create and apply Sankey charts to streamline your process.

Sankey chart creation

To create a Sankey chart, you will need to have a basic understanding of flowcharting and chart design. Here are the steps to create a simple Sankey chart:

1. Start by choosing a software program that supports Sankey chart creation. Some popular options include Microsoft Visio, Lucidchart, and Gliffy.
2. Begin by adding a main node to your chart. This will be the starting point for the flow of materials, energy, or information.
3. Connect the main node to one or more source nodes, which represent the inputs to the system. These sources can include raw materials, water, energy, or other inputs.
4. Add intermediate nodes to the chart, which represent the steps or processes involved in the system. These nodes can include manufacturing, processing, or other steps.
5. Connect the intermediate nodes to the source nodes to create a flow of materials, energy, or information. You can also add branching paths to the chart to represent different streams or outputs.
6. Add sink nodes to the chart, which represent the outputs or destinations of the system. These can include products, finished goods, or other outputs.
7. Connect the sink nodes to the intermediate nodes to complete the flowchart.

Sankey chart applications

Once you have created your Sankey chart, you can use it to identify and address inefficiencies and opportunities for improvement. Here are a few examples of how Sankey charts can be used:

1. Process optimization: Sankey charts can be used to identify bottlenecks and inefficiencies in a process. By analyzing the flow of materials, energy, or information through the process, you can identify areas where improvements can be made.
2. Carbon footprint analysis: Sankey charts can be used to visualize the flow of materials, energy, or information through a system, and to identify carbon emissions. By visualizing the flow, you can identify areas where emissions can be reduced, such as by using more efficient energy sources or improving the efficiency of manufacturing processes.
3. Supply chain management: Sankey charts can be used to visualize the flow of materials, energy, or information through a supply chain, and to identify potential bottlenecks or inefficiencies. By analyzing the flow, you can identify opportunities for improvement and optimize the efficiency of the supply chain.

In conclusion, Sankey charts are a powerful tool for visualizing and optimizing the flow of materials, energy, or information through a system. By creating and applying Sankey charts, you can identify inefficiencies, improve efficiency, and reduce emissions. Whether you are a process planner, a sustainability consultant, or a supply chain manager, Sankey charts can be a valuable tool in streamlining your process.
