In today’s hyper-connected world, supply chains are as essential to business operations as the transportation networks that connect countries. From manufacturing to retail, a well-designed supply chain often plays a crucial role in achieving profitability and market share. A critical component of a well-functioning supply chain is the ability to identify and analyze the flow of valuable materials, information, and products. This can be achieved through the use of diagrams and charts such as Sankey diagrams. In this article, we will explore the basics of Sankey diagrams and demonstrate how they can be used to unlock the potential of supply chains.
What is a Sankey Diagram?
A Sankey diagram is a geometric representation of the flow of a material, such as a product or a resource, through multiple elements or sources and multiple destinations. It is often used to show how a process of value creation is created and broken down, highlighting dependencies and dependencies between different elements of a supply chain. Sankey diagrams are commonly used in supply chain management, cost accounting, and other fields where accurate visualization of the flow of data and information is crucial.
How to draw a Sankey Diagram
To create a Sankey diagram, start by gathering all the data you need to represent the flow of materials, resources, and information through your supply chain. This data should include the flow of materials, resources, and information from various sources and destinations. The diagram should show each element or source and destination and should include all the flow elements between them.
Once you have all the data, you can begin drawing the Sankey diagram. Start by drawing a starting node (source) and a finish node (destination) at the beginning and end of the diagram. Draw a line connecting each point representing a flow element between the nodes. Label each element so that it represents the direction of the flow of the material or resource. Finally, connect each line with a number to show how much material or resource is flowing through the line.
Applications of Sankey Diagrams
Sankey diagrams can be used to analyze a variety of supply chains and other processes, including product development, manufacturing, distribution, and inventory management. They are particularly useful in supply chain management where a thorough analysis of the flow of materials, information, and resources can help identify bottlenecks, inefficiencies, and other potential areas for improvement.
For example, a company that manufactures a product can use a Sankey diagram to visualize the material and resource flows through the supply chain from the supplier to the factory, up the production line, and to the warehouse. The diagrams can show how materials and resources are being consumed and produced, allowing the company to identify areas where improvements can be made.
Sankey diagrams can also be used in the field of cost accounting to analyze the flow of materials and resources through a company’s supply chain. This can help identify areas where the company can reduce costs and improve profitability.
Conclusion
In conclusion, Sankey diagrams are a powerful tool for unlocking the potential of supply chains and other processes. They provide a visual representation of the flow of materials, information, and resources, and can be used to identify bottlenecks, inefficiencies, and other potential areas for improvement. Whether used in supply chain management, cost accounting, or any other field, Sankey diagrams can help companies improve their operations and make better decisions.
