Sankey charts are a type of visual tool used in process analysis, costing analysis, and process modeling. Unlike traditional bar charts, line charts, and pie charts, these charts offer a unique perspective on the flow of information, which can help to illustrate complex and often interconnected processes. In this article, we will discuss how to create an effective Sankey chart and provide applications to help streamline processes.
The Basics of Sankey Charts
A Sankey chart is a type of flowchart that is often used for visualizing complex, interconnected processes. The chart is composed of two main components: nodes and flows. Nodes represent the entities, processes, or activities that are being analyzed, while flows represent the information or resources that pass through these entities over time. These nodes and flows are depicted on the chart as lines that are connected to each other, indicating the direction and amount of flow.
To create a Sankey chart, you will need to identify the nodes, activities, and flows that you want to visualize and then organize them using a network diagram. Once the flowchart has been created, you can then add scales and labels to the diagram to make it easier to read and interpret.
Applications of Sankey Charts
Sankey charts can be used for a wide range of applications, including process analysis and costing, project management, regulatory compliance, and environmental analysis. Some commonly used Sankey charts include process flow diagrams, costing flowcharts, and regulatory analysis charts. These types of Sankey charts are often used in conjunction with more traditional process analysis techniques, such as PDCA cycles or Six Sigma methodologies.
In the field of process analysis, Sankey charts can be used to visualize the flow of information and resources throughout a process, identifying the bottlenecks and opportunities for improvement. In project management, Sankey charts can be used to track the progress and resource allocation of a project, helping to identify areas for optimization. Regulatory compliance and environmental analysis charts can also be used to visually represent the flow of information and resources through a company or organization, helping to identify areas for improvement or compliance with regulations.
Creating an Effective Sankey Chart
While Sankey charts can be complex, there are some general steps that you can follow to create an effective Sankey chart:
1. Identify the entities and processes you want to visualize and determine the appropriate node labels.
2. Determine the direction and amount of flow by selecting the appropriate flow label and line type.
3. Label the nodes and flows using appropriate scales and labels, and ensure that the chart is easily interpretable.
4. Use annotations and legends to clarify the meaning of the flowchart.
Once the Sankey chart has been created, you can use it in combination with other analytical techniques to analyze the flow of information and resources throughout a process. By visualizing complex processes using Sankey charts, you can gain a better understanding of the flow and identify areas of improvement.
