Streamlining processes is essential for businesses to improve efficiency and productivity. One way to do this is by using Sankey charts, a visual representation of the flow of materials, services, or information between different processes or departments. In this article, we’ll provide a guide on how to create and apply Sankey charts for streamlining processes.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that is used to display the flow of materials, services, or information between different processes or departments. It was originally developed by a Swiss engineer named Charles Sankey in the early 20th century.

Sankey charts are particularly useful for identifying bottlenecks, inefficiencies, and areas that require improvement in a process. They are also helpful for understanding interdependencies between different components of a system.

Creating a Sankey Chart

There are several software programs that can be used to create Sankey charts, including Microsoft Excel, Visio, and Lucidchart. However, the process of creating a Sankey chart typically involves the following steps:

1. Identify the different processes or departments that you want to include in the chart.
2. Gather data on the flow of materials, services, or information between these processes or departments, including the quantity, frequency, and other relevant details.
3. Organize the data into a spreadsheet or table, with the source process and the destination process on separate rows.
4. Create a Sankey chart using the software program of your choice, starting with the source process and adding branches for each of the destination processes.
5. Customize the chart by adding titles, labels, and other visual elements to make it easier to understand and interpret.

Applications of Sankey Charts

Sankey charts are a powerful tool for streamlining processes and improving efficiency. They can be applied in a variety of industries and contexts, including:

1. Manufacturing: Sankey charts can be used to visualize the flow of materials between different stages of the manufacturing process, including raw materials, assembly, testing, and packaging.
2. Supply Chain: Sankey charts are useful for identifying bottlenecks and inefficiencies in the supply chain, and for mapping out alternative routes and suppliers.
3. Service Industry: Sankey charts can be used to visualize the flow of information between different departments within a service organization, such as customer service, technical support, and sales.
4. Business Analysis: Sankey charts can be used to identify areas that require improvement in a business process, such as reducing lead times or improving quality control.
5. Organizational Design: Sankey charts can be used to visualize the flow of information and resources within an organization, and to identify areas where processes could be streamlined or integrated.
