Title: Introduction
As our world becomes increasingly interconnected and resource-driven, understanding the flow of resources is crucial for effective decision-making. One tool that is increasingly being used to visualize the flow of resources is the Sankey chart. This article aims to explore the creation and applications of Sankey charts using an example.
Introduction of Sankey Chart
A Sankey diagram is a diagram created using a series of arrows connecting resources to sinks. The number on each arrow shows the amount of resources they carry. The diagram helps in understanding how resources are distributed between various sources and sinks.
The diagram is commonly used in project management, logistics, engineering design, and other fields where resources need to be allocated efficiently. By having a clear picture of the flow of resources, decision-makers can make informed decisions that maximize the effectiveness of resources.
Sankey Chart Creation Example
Sankey charts are typically created using a software tool, such as Microsoft Excel, Google Sheets, or even through a simple manual diagram. Here is a simple example of how to create a Sankey chart using Microsoft Excel:
1. Create a diagram with resource sources on one side, sinks on the other side, and arrows connecting them. The number on each arrow shows how much resource is being transported.
2. Use different colors for each resource source/sink to make it easier to read the diagram.
3. Remove the labels for the source and sink to make it easier to distinguish between them.
Example of Sankey Chart Interpretation
The Sankey chart above shows an example of the flow of resources between a source (A) and a sink (B). At the source, resources are being produced and transported by the arrows connecting the source to the destination. As resources transit through the diagram, the number on each arrow shows the amount of resources being transported.
To interpret the information on the diagram, you need to look at the location where the arrows are coming from and going to. For instance, since the destination (B) is indicated by green arrows, you can assume that resources are flowing toward B. Similarly, if you notice that resources are flowing through the diagram in red colors in the example, you can assume these resources are moving away from A.
Effective Communication With Sankey Charts
Sankey charts are an incredibly effective tool for communication, particularly for complex resource allocation tasks. They enable stakeholders to understand how resources are being used, which reduces misunderstandings and misinterpretations that can arise during resource allocation decisions.
By breaking down the flow of resources into separate diagrams for each resource type, stakeholders can quickly identify any bottlenecks or sources of waste. This can lead to more informed and effective resource allocation.
Conclusion
Sankey charts are the perfect resource to visualize the flow of resources efficiently. They provide an effective medium for communication and understanding complex resource allocation issues in various fields. Using Sankey charts to create diagrams for resource planning, project management, and logistics, helps decision-makers make data-driven decisions that boost effectiveness and efficiency in using resources effectively.
