Sankey charts are a powerful tool for visualizing process flow and identifying opportunities for improvement. They are often used in process mapping, capacity planning, and network analysis.

Sankey charts are named after a British engineer named Frank Sankey who developed the method in the 1920s. The charts are particularly useful when there are multiple inputs and outputs, making it easier to see the relationships between different processes.

To create a Sankey chart, you will need to have a process map that shows the flow of inputs and outputs. This can be done using a variety of methods such as mapping, flowcharting, or process modeling software. Once you have a process map, it is time to create the Sankey chart.

The first step in creating a Sankey chart is to separate the process into inputs and outputs. You can do this by drawing a horizontal line across the process map, dividing it into two separate sections. The left section represents inputs and the right section represents outputs.

Next, you will need to assign values to each input and output. The values represent the amount of each input or output that flows through the process. These values can be measured in units such as person-hours, dollars, or units of time.

Once you have assigned values to each input and output, you can begin to draw the Sankey chart. The chart is made up of three main components: input, process, and output streams. The input and output streams are located at the top and bottom of the chart, respectively, and represent the overall flow of the process. The process stream is located in the middle and represents the intermediate steps in the process.

Each input stream is represented by a filled triangle, and each output stream is represented by an empty triangle. The process stream is made up of small triangles that represent the individual steps in the process. The size of the triangles is proportional to the flow of inputs and outputs through the process.

Sankey charts can be used for a variety of purposes, including process mapping, capacity planning, and network analysis. By visualizing the flow of inputs and outputs, Sankey charts can help you identify opportunities for improvement and streamline your processes.

In conclusion, Sankey charts are a powerful tool for visualizing process flow and identifying opportunities for improvement. They are particularly useful when there are multiple inputs and outputs, making it easier to see the relationships between different processes. By creating Sankey charts, you can gain a better understanding of your processes and make informed decisions about how to improve them.
