Title: Streamlining Your Data with Sankey Charts: A Visual Guide to Process Improvement

Sankey charts are a data visualization tool that can be used to represent the flow of materials, people, or information between different entities. They are particularly useful for identifying bottlenecks, optimizing processes, and improving efficiency. In this article, we will show you how to create and apply Sankey charts to streamline your data.

Part 1: Understanding Sankey Charts

Sankey charts were originally developed to visualize the flow of materials between different industrial processes. Today, they are widely used in various fields, including finance, logistics, and healthcare, to represent the flow of people, ideas, or information.

A Sankey chart consists of two main parts: the input entities (the sources) and the output entities (the sinks). The chart shows the flow of entities from the input zone to the output zone, but it does not show the flow between individual entities within each zone.

Part 2: Creating a Sankey Chart

There are several software programs that can be used to create Sankey charts, including Microsoft Excel, Google Sheets, and specialized Sankey chart software like Prominy. In this article, we will show you how to create a Sankey chart in Microsoft Excel.

Step 1: Prepare Your Data

To create a Sankey chart, you need to have a dataset that contains input and output entities, as well as the flow of entities between them. The dataset can be any type of data, as long as it is in a tabular format.

Step 2: Set Up Your Excel Sheet

Open a new Excel spreadsheet and click on the insert tab. Then, click on the chart icon in the toolbar. Choose Sankey chart from the dropdown menu.

Step 3: Customize the Chart

To customize the chart, you can use the chart properties in the Design tab. For example, you can change the colors of the chart, add a title, or set the axis labels.

Step 4: Add Your Data

In the Sankey chart, input entities are represented by the top area, and output entities are represented by the bottom area. The flow of entities between the input and output areas is shown as arrows.

To add your data to the chart, highlight the cells in your dataset that contain the input entities, output entities, and the flow of entities. Then, select the entire highlighted data range and click and drag to add it to the Sankey chart.

Part 3: Analyzing Your Data with Sankey Charts

Once the Sankey chart is created, you can analyze the data to identify bottlenecks, optimize processes, and improve efficiency. Here are some tips for analyzing your Sankey chart:

1. Look for imbalances in the flow of entities. Are some input or output entities much larger or smaller than others? If so, this could indicate a bottleneck or a problem with the process.
2. Check the flow of entities between input and output areas. Is the flow smooth and steady, or are there sudden increases or decreases in the flow? If the flow is irregular, this could indicate a problem with the process.
3. Look for opportunities for process improvement. Are there areas where multiple entities are produced or consumed, but there is little flow of entities between them? If so, this could indicate a potential for greater efficiency.

Part 4: Conclusion

In conclusion, Sankey charts are a powerful tool for visualizing the flow of materials, people, or information between different entities. By creating and analyzing Sankey charts, you can identify bottlenecks, optimize processes, and improve efficiency. Whether you are a student, a business owner, or an
