Streamlining processes is essential for organizations to optimize their operations and improve overall efficiency. Sankey charts are a powerful visualization tool that can help you identify inefficiencies and opportunities for improvement in your processes. In this article, we will explore how to create Sankey charts and the various applications of this visual representation.
What are Sankey Charts?
Sankey charts are a type of flowchart that use directed branches to represent data movement from one place to another. They are named after Swiss engineer Victor Sankey, who patented the design in 1904. Sankey charts can be used to represent a wide range of processes, including production, supply chain, and financial management.
Key features of Sankey charts include:
- Directed branches: Sankey charts use directed branches to represent data flow. This means that the arrows in the chart always point from the source to the sink.
- Flow values: Each branch in the chart can be assigned a flow value, which represents the amount of data or material that moves between two points.
- Data inputs and outputs: Sankey charts can be used to represent data inputs and outputs, as well as internal processes within a system.
How to create a Sankey Chart
Creating a Sankey chart is straightforward, and there are several software options available that can help you design and create your chart. Here are the general steps to create a Sankey chart:
- Determine the purpose of your Sankey chart: Before creating your chart, it is important to define the purpose and scope of your chart. This will help you determine the data inputs, outputs, and internal processes that need to be represented in your chart.
- Collect data: Gather the necessary data to create your Sankey chart. This may include flow values, process names, or other relevant information.
- Choose a software: Select a software program that supports Sankey chart creation. Some popular options include Visio, Microsoft Excel, and ProcessOn.
- Design your chart: Use the software to create your chart, and design the branches to represent your data inputs, outputs, and internal processes.
- Assign flow values: Once your chart is designed, assign flow values to each branch to represent the amount of data or material that moves between two points.
- Review and refine: Review your chart to ensure that it accurately represents your data and provides valuable insights. Refine as necessary until you are satisfied with the results.
Applications of Sankey Charts
Sankey charts can be used in a wide range of industries and applications to help organizations streamline processes and identify inefficiencies. Some common applications of Sankey charts include:
- Supply Chain Management: Sankey charts can be used to visualize the flow of goods and services through a supply chain, and help identify areas for improvement in logistics and inventory management.
- Process Improvement: Sankey charts can be used to represent a process, identify key inputs and outputs, and identify opportunities for process improvement.
- Financial Analysis: Sankey charts can be used to represent the flow of revenue and expenses in a financial system, and help identify areas for cost reduction or revenue optimization.
- Environmental Monitoring: Sankey charts can be used to represent the flow of pollutants through an environmental system, and help identify sources of pollution and areas for improvement.
- Project Management: Sankey charts can be used to represent a project schedule, identify dependencies, and help identify areas for improvement in project management.
