Unleashing the Power of Sankey Charts: A Visual Exploration of Process Flow and Optimization

Sankey charts are an effective way to visualize process flow and identify opportunities for optimization. In this article, we will explore how to create Sankey charts, their applications, and the benefits they bring to businesses looking to improve their operations.

What are Sankey Charts?

Sankey charts, also known as Sankey diagrams or directed flow diagrams, are a type of process flow chart that shows the direction of the flow between different components or steps. Unlike regular flowcharts, which depict the movement of materials or information in a single direction, Sankey charts highlight the flow of both materials and information between different components or steps.

Sankey charts are named after the English chemist, Sidneycolorado Sankey, who invented the chart in the 1890s. Sankey charts are widely used in engineering, manufacturing, and quality management to visualize and optimize process flow, identify bottlenecks, and improve efficiency.

How to Create Sankey Charts

To create a Sankey chart, you need to follow a few basic steps:

Identify the components or steps in the process you want to visualize. These components or steps can be physical processes, such as manufacturing or assembly, or they can be abstract steps, such as decision-making or communication.
Determine the direction of the flow between each component or step. For example, a flowchart for a manufacturing process might show the direction of raw material flow from the supplier to the assembly line, and the direction of finished product flow from the assembly line to the shipping department.
Draw the chart on a piece of paper, using arrows to show the flow of materials or information between each component or step. The chart should show the relative quantities or intensities of the flow, as well as any bottlenecks or other issues that can affect the efficiency of the process.
Use software or online tools to create more detailed or complex Sankey charts if needed. There are many programs and online tools available that can help you create Sankey charts, such as Processon, Gliffy, and SmartDraw.

Applications of Sankey Charts

Sankey charts are useful in a wide range of industries and fields, including manufacturing, logistics, finance, and healthcare. Here are some examples of how Sankey charts can be used to improve process flow and efficiency:

Manufacturing: Sankey charts can be used to visualize and optimize the flow of materials through a manufacturing process, from raw materials to finished products. By identifying bottlenecks and inefficiencies, manufacturers can make changes to improve the speed and accuracy of their production lines.
Logistics: Sankey charts can be used to visualize and optimize the flow of goods and services through a logistics network, from suppliers to customers. By identifying bottlenecks and inefficiencies, logistics companies can make changes to optimize their routes, reduce transportation costs, and improve delivery times.
Finance: Sankey charts can be used to visualize and optimize the flow of funds through a financial system, from investors to businesses. By identifying bottlenecks and inefficiencies, financial institutions can make changes to improve the speed and accuracy of their loan processing and investments.
Healthcare: Sankey charts can be used to visualize and optimize the flow of patients and medical information through a healthcare system, from providers to patients. By identifying bottlenecks and inefficiencies, healthcare professionals can make changes to improve the speed and accuracy of patient care and诊断.
