Sankey charts are a type of flowchart that are used to visualize and analyze the flow of materials, energy, or information through a system or process. They are particularly useful for identifying opportunities for improvement and optimizing resource utilization. In this article, we will explore the creation and applications of Sankey charts, and provide tips for streamlining your own processes.

Sankey chart creation

Sankey charts can be created using a variety of software programs, including Microsoft Excel, Lucidchart, Visio, and more. The basic process for creating a Sankey chart involves the following steps:

1. Identify the flow of materials, energy, or information you want to visualize. This could include a process for manufacturing a product, a supply chain, or the flow of data between different parts of an organization.
2. Create a list of the various steps or processes involved in the flow.
3. Determine the inputs and outputs of each step, and use arrows to connect them.
4. Assign a Sankey index number to each flow, with the smallest index number representing the largest flow.
5. Use shapes to represent the various steps or processes, and add labels to provide additional information.
6. Customize the chart design as needed, including adding colors, shapes, or additional data visualizations.

Using Sankey charts

Once you have created a Sankey chart, there are a number of ways you can use it to analyze and improve your processes. Here are a few examples:

1. Identifying bottlenecks: Sankey charts can help you identify areas where material, energy, or information is being wasted or delayed. By examining the flow of the system, you can determine where there are bottlenecks or other sources of inefficiency, and take steps to address them.
2. Prioritizing improvements: Sankey charts can also be used to prioritize improvements to your system or process. By assigning a Sankey index number to each step, you can focus on the areas that have the greatest impact on the overall flow.
3. Optimizing resource utilization: Sankey charts can help you identify opportunities to optimize the use of resources, such as raw materials, energy, or labor. By examining the flow of the system, you can determine where resources are being underused or overused, and make changes to improve efficiency.
4. Communicating changes: Sankey charts can be a useful tool for communicating changes to your processes to team members, stakeholders, or other stakeholders. By visually mapping out the flow of material, energy, or information, you can easily explain complex processes in a clear and concise way.

Tips for streamlining your processes

While Sankey charts can be a valuable tool for analyzing and improving your processes, it’s important to keep in mind that they are just one part of a larger process optimization strategy. Here are a few tips for streamlining your processes:

1. Start by identifying the biggest pain points in your processes. What are the areas where you are wasting time, resources, or money?
2. Break down larger processes into smaller, more manageable steps. This can make it easier to identify and address bottlenecks and other sources of inefficiency.
3. Prioritize improvements based on the impact they will have on the overall flow of your processes. Don’t get caught up in small fixes that won’t make a significant impact on the system as a whole.
4. Communicate any changes you make to your processes to your team members and other stakeholders. This can help ensure everyone is working together toward a common goal.
5. Continuously monitor and measure the effectiveness of your improvements. This can help you make necessary adjustments as you go along, and ensure that you are making progress toward your goals.
