Streamlining processes is essential for organizations looking to improve efficiency and reduce costs. One powerful tool that can help achieve these goals is Sankey charts, a visual representation of processes and the materials and information they produce.

Sankey charts are named after a Dutch engineer named Henk van der Grinten, who developed the technique in the 1960s. They are used to identify and optimize process flows, and they can be used in a wide range of industries, including manufacturing, logistics, and healthcare.

Here’s a step-by-step guide to creating and applying Sankey charts:

Step 1: Define the process

To create a Sankey chart, you need to define the process you want to analyze. This involves identifying the inputs, outputs, and steps in the process. It’s important to be as specific and detailed as possible, as this will make it easier to identify opportunities for optimization.

Step 2: Set up the Sankey chart

Once you have defined the process, you can set up the Sankey chart in a software program such as Process Mirror, GanttPRO, or Microsoft Visio. This involves creating a flowchart that represents the process, and then adding arrows to indicate the direction and type of flow (e.g., inputs, outputs, or data flows).

Step 3: Identify opportunities for optimization

Once the Sankey chart is set up, you can start analyzing the process. Look for opportunities for improvement, such as unnecessary steps, bottlenecks, or inefficiencies. Consider factors such as cost, time, and resources when making decisions about how to optimize the process.

Step 4: Implement changes

Once you have identified opportunities for optimization, implement the changes in the process. This may involve rearranging steps, eliminating unnecessary activities, or using new technology or processes.

Step 5: Monitor and measure results

After making changes to the process, monitor and measure the results to see if the optimization efforts were successful. Review the Sankey chart to see if the changes have had the desired impact on the process, and make further adjustments as needed.

Sankey charts are a powerful tool for streamlining processes and optimizing workflows. By following the steps outlined above, you can create and apply Sankey charts to identify and address inefficiencies in your processes, ultimately improving productivity and reducing costs for your organization.
