Sankey charts are a powerful visual tool for understanding and optimizing workflows. They are commonly used in process mapping and identifying opportunities for improvement. In this article, we will guide you through the process of creating a Sankey chart and provide examples of how these charts can be used in different industries to streamline processes and improve efficiency.

What are Sankey charts?
Sankey charts are a type of flowchart that are used to represent the flow of materials or information through a process. They are named after Swedish工程师 H. Sankey, who developed the technique in the early 20th century. Sankey charts are particularly useful for identifying bottlenecks and areas where waste occurs in a process, as well as opportunities for improvement.

How to create a Sankey chart
To create a Sankey chart, you will need to follow these steps:

1. Identify the process you want to map out. This could be a manufacturing process, a service operation, or any other workflow you want to understand.
2. Gather data on the inputs and outputs of the process, as well as the steps involved. This information should be gathered from interviews with stakeholders, observation of the process, or other sources.
3. Create a Sankey chart using a software program such as Microsoft Visio, Lucidchart, or draw.io.
4. Draw the process in the center of the chart, including the inputs, outputs, and steps.
5. Use arrows and labels to connect the inputs to their corresponding outputs, and the steps in the process.
6. Use colors, shapes, or other visual aids to differentiate between different types of work or materials.
7. Label the chart with key performance indicators or other relevant metrics to help understand the effectiveness of the process.

Applications of Sankey charts
Sankey charts are useful in a variety of industries, including manufacturing, healthcare, finance, and marketing. Here are some examples of how Sankey charts can be used to streamline processes and improve efficiency:

1. Manufacturing: A Sankey chart can be used to map out the production process, highlight bottlenecks and areas for improvement, and identify opportunities to optimize the process.
2. Healthcare: A Sankey chart can be used to map out the patient care process, identify areas where communication breakdowns can occur, and highlight opportunities for training or process improvements.
3. Finance: A Sankey chart can be used to map out the loan process, identify bottlenecks in underwriting and approval, and improve the overall efficiency of the loan process.
4. Marketing: A Sankey chart can be used to map out the marketing process, identify areas where customer data can be better integrated, and improve the overall effectiveness of marketing campaigns.

Conclusion
Sankey charts are a useful visual tool for understanding and optimizing workflows. By mapping out the inputs and outputs of a process, and using arrows and labels to connect the different steps involved, Sankey charts can help identify areas for improvement and improve overall efficiency. Whether you are in manufacturing, healthcare, finance, or marketing, a Sankey chart can be a valuable tool for streamlining processes and improving efficiency.
