Sankey charts are a powerful visualization tool that can be used to show the flow of material, energy, or information through a system. They are useful for process improvement because they allow you to easily identify bottlenecks, inefficiencies, and opportunities for improvement.
Sankey charts are named after their creator, Dr. Charles Sankey, an American author and artist who published his first Sankey chart in 1908. Since then, they have become a popular tool for process improvement and are widely used in a variety of industries, including manufacturing, logistics, and supply chain management.
To create a Sankey chart, you need to gather data on the flow of material, energy, or information through the system. This data can be represented as a flow network, where nodes represent the different stages in the process and the edges represent the flow of materials, energy, or information between those stages.
Next, you need to assign a weight to each edge in the flow network. This weight represents the amount of material, energy, or information that flows through that edge. You can also add labels to the nodes and edges to provide more context and information about the process.
Once the data is entered into the flow network, you can use specialized software or tools to create a Sankey chart. Sankey charts typically show the flow of materials, energy, or information through the system in a hierarchical or tree-like structure. This structure allows you to quickly identify the main sources and sinks of the material, energy, or information and the key bottlenecks and inefficiencies in the process.
Sankey charts can be used to identify a variety of opportunities for improvement. For example, you can use them to identify bottlenecks in the process that are causing delays or inefficiencies. You can also use them to identify opportunities to optimize the use of materials, energy, or information, such as by reducing excess inventory or improving product quality.
In conclusion, Sankey charts are a powerful visualization tool that can be used to show the flow of material, energy, or information through a system. They are useful for process improvement because they allow you to easily identify bottlenecks, inefficiencies, and opportunities for improvement. By gathering data on the flow of materials, energy, or information through the system and creating a Sankey chart, you can gain valuable insights and make improvements to increase efficiency and productivity.
