Sankey charts are a powerful visualization tool used to represent the flow of resources or materials between different entities. They are useful in highlighting potential bottlenecks, identifying opportunities for improvement, and guiding decision-making. In this article, we will explore the creation and applications of Sankey charts for effective resource allocation.

What are Sankey Charts?

Sankey charts, also known as flowcharts, are a type of diagram that depict the direction of a flow of resources or materials between different entities. They are named after the British engineer and inventor William Sankey, who invented the first Sankey chart in 1911.

Sankey charts are particularly useful for visualizing the flow of resources or materials between different organizations or departments within an enterprise. They are useful for identifying bottlenecks and areas for improvement in resource allocation, as well as for guiding decision-making.

Creation of Sankey Charts

Sankey charts can be created using a variety of software tools, such as Microsoft Visio, Lucidchart, or SmartDraw. These tools provide a range of templates and shapes to create the Sankey chart, as well as the ability to customize the chart to fit the needs of the specific situation.

To create a Sankey chart, begin by determining the entities that will be included in the chart, as well as the flow of resources or materials between these entities. Next, import the chart template into the chosen software tool, and use the available shapes to add each entity and the flow of resources or materials between them.

Analyzing Sankey Charts

Once a Sankey chart has been created, it is possible to analyze it to gain insights into resource allocation. Some key areas to look at when analyzing a Sankey chart include:

1. Identifying Bottlenecks: A Sankey chart can help identify bottlenecks in the flow of resources or materials between different entities. This can be particularly useful for identifying places where waste or inefficiencies may be occurring.
2. Identifying Opportunities for Improvement: By examining the flow of resources or materials between different entities, a Sankey chart can help identify opportunities for improvement. This might include suggestions for streamlining processes, reducing waste, or reallocating resources to different areas of the enterprise.
3. Guiding Decision-Making: Sankey charts can be used to guide decision-making by providing a visual representation of resource flow and highlighting areas for improvement.

Applications of Sankey Charts

Sankey charts have a wide range of applications in different industries and sectors. Some examples include:

1. Manufacturing: Sankey charts can be used to visualize the flow of materials and resources between different stages of the manufacturing process, helping to identify bottlenecks and inefficiencies.
2. Supply Chain Management: Sankey charts can be used to visualize the flow of resources or materials between different stages of the supply chain, helping to identify potential bottlenecks or areas for improvement.
3. Nonprofit Organizations: Sankey charts can be used to visualize the flow of resources or funds between different programs or departments within a nonprofit organization, helping to identify areas for improvement and guide decision-making.
4. Hospitality: Sankey charts can be used to visualize the flow of resources or materials between different areas of a hotel or resort, such as between the front desk and the kitchen.

In conclusion, Sankey charts are a powerful visualization tool that can be used to represent the flow of resources or materials between different entities. By highlighting potential bottlenecks, identifying opportunities for improvement, and guiding decision-making, Sankey charts can be an essential tool for effective resource allocation in a wide range of industries and sectors.
