Unleashing the Power of Sankey Charts for Process Visualization

The Sankey chart, also known as the force-directed Sankey diagram, is a powerful visualization tool for process flow and network interactions. It has become increasingly popular in recent years due to its ability to easily depict complex processes and identify key performance indicators (KPIs). In this article, we will discuss how Sankey charts can be used to improve process visualization and enhance decision-making capabilities.

The Basics of Sankey Chart Creation

A Sankey chart is a type of directed graph that displays the flow of matter, energy, or information between different nodes. Each node represents a process step, while the directed edges between nodes represent the flow of energy or information through the system. The chart is named after William Sankey, an American cartoonist and engineer who first introduced the concept in the early 1900s.

Sankey charts can be created using various software tools, including Microsoft Excel, PowerPoint, or specialized visualization software such as Visio, Gliffy, or Lucidchart. To create a basic Sankey chart, follow these steps:

1. Define the process steps and nodes: Identify the key processes in your system and create nodes for each step.
2. Determine the direction of the edges: Indicate the direction of the flow between each pair of nodes, whether it is from the source (input) to the sink (output) or vice versa.
3. Assign weights or values to the edges: If necessary, assign weights or values to the flow between each pair of nodes to represent KPIs or other performance metrics.
4. Customize the chart appearance: Format the chart to suit your needs, such as adding captions, formatting the edges, or changing the color scheme.

Applications of Sankey Charts for Process Visualization

Sankey charts are highly versatile and can be applied to a wide range of industries and processes. Here are some examples of the ways Sankey charts can be used for process visualization:

Sales Process Visualization

Sankey charts can be used to visualize the sales process, from initial prospecting to closed deal. By assigning weights or values to the edges, you can easily identify the most important steps in the process and the KPIs that drive performance.

Supply Chain Management

Sankey charts can be used to visualize the flow of goods and services through the supply chain. By showing the route taken by each product, you can identify inefficiencies in the chain and make improvements to reduce costs and improve delivery times.

Financial Analysis

Sankey charts can be used to visualize the flow of cash between different accounts or entities. By assigning weights or values to the edges, you can easily identify the most important sources and sinks of cash and the KPIs that are driving financial performance.

Marketing Campaigns

Sankey charts can be used to visualize the flow of leads through a marketing campaign. By assigning weights or values to the edges, you can easily identify the most effective channels and tactics for generating leads and boosting conversions.

Conclusion

Sankey charts are a powerful tool for process visualization and analysis. They provide a clear and intuitive way to show the flow of energy, information, or materials through complex systems and identify key performance indicators. By following the steps outlined in this article, you can easily create and apply Sankey charts to improve your processes and make better decisions.
