Sankey charts are a type of diagram that help organizations visualize data flow and relationships between different entities. They are particularly useful in business analysis, where they can help uncover insights and trends in large datasets. In this article, we will provide an overview of how to create and use Sankey charts for business analysis, with step-by-step instructions and examples.

Importance of Sankey Charts for Business Analysis

There are several reasons why Sankey charts are valuable tools for business analysis:

1. They reveal hidden relationships: Sankey charts can help identify non-obvious relationships between different entities and their data flow. By breaking down complex data structures, they highlight the relationships between variables and show how they are interconnected.
2. They provide a visual representation of data: By using simple, interpretable shapes and colors, Sankey charts make it easier to visualize and understand complex data structures and relationships, allowing analysts to quickly identify patterns and trends.

Creating Sankey Charts for Business Analysis

1. Define Your Data: Determine what data you want to visualize and how it should be organized. This will help determine the appropriate layout for your Sankey chart.
2. Map out your data: Create a data table that outlines the relationships between the entities you want to represent. This should include the names of the entities and their associated data flows.
3. Choose your shapes: Sankey charts are typically created using shapes representing the different entities, and arrows representing the flow of data. Choose the appropriate shapes for your data (e.g. triangle for an entity, bar for flow).
4. Design your layout: This will depend on the data you have and how you want to present it. Generally, the number of rows will be equal to the number of entities you are visualizing, while the number of columns will equal the number of arrows representing data flow.
5. Add colors and annotations: To give your Sankey chart some visual interest, you can add different colors or annotations to represent different types of data.

Sankey Chart Applications in Business Analysis

Sankey charts have various applications in business analysis, including:

1. Risk analysis: By visualizing risks associated with different scenarios, such as different possible outcomes, investors can better understand the potential impact of various events and make more informed decisions.
2. Supply chain analysis: Sankey charts can help identify the interdependencies between different suppliers and transportation methods, allowing organizations to optimize costs and improve overall performance.
3. Marketing analysis: By examining the flow of customers through different channels, businesses can identify opportunities to expand their market reach and increase revenue.

Conclusion

In conclusion, Sankey charts can be a powerful tool for business analysis. They give a visual representation of data, reveal hidden relationships and provide insights that may not have been apparent otherwise. While creating a Sankey chart may seem daunting at first, with a clear understanding and following a few simple steps, it can be a valuable addition to any business analyst’s toolkit.
