A Sankey chart, also known as aSankey diagram, is a type of flowchart that is commonly used to visualize and analyze the flow of materials, funds, or data between different entities. It is an effective tool for identifying bottlenecks and areas of inefficiency in a system, and for optimizing processes to improve efficiency and profitability. Here are 10 tips for using Sankey diagrams to analyze and improve your business processes:
- Identify the key entities and processes in your system: The first step in creating a Sankey chart is to determine the key entities and processes that are involved in your system. These may include suppliers, customers, inventory levels, manufacturing processes, sales channels, and more.
- Determine the flow of materials, funds, or data: Once you have identified the key entities and processes, you need to determine the flow of materials, funds, or data between them. This may involve analyzing sales records, inventory management systems, financial reports, and other data sources to identify the flow of goods, services, or data.
- Choose the size and orientation of the chart: The size and orientation of your Sankey chart are critical for accurately representing the flow of materials, funds, or data between your key entities and processes. It is important to choose the appropriate size for your chart based on the scale of your data, and to orient it so that the flow of material, funds, or data is from the top-left to the bottom-right.
- Label the key entities and processes: It is important to clearly label the key entities and processes in your Sankey chart to make it easier to understand and interpret. Use clear and concise labels that accurately reflect the nature of the entity or process.
- Identify and highlight bottlenecks and areas of inefficiency: A Sankey chart can help you identify areas where materials, funds, or data are flowing less efficiently, such as bottlenecks in manufacturing processes or low-selling products in a retail store. By highlighting these areas, you can develop strategies to improve efficiency and profitability.
- Use colors and patterns to differentiate flow pathways: To make your Sankey chart more visually appealing, you can use colors and patterns to differentiate the flow pathways between your key entities and processes. For example, you can use different colors to represent different types of materials, or patterns to represent different stages in a manufacturing process.
- Add annotations and captions: To make your Sankey chart more informative, you can add annotations and captions that provide additional context and explanation. This may include detailed descriptions of each entity or process, or explanations of the overall goals and objectives of your system.
- Review and revise your Sankey chart: After creating your Sankey chart, it is important to review and revise it to ensure that it accurately represents your system and provides actionable insights. You may need to make adjustments to the chart based on new data or changes to your system.
- Communicate your findings to stakeholders and decision-makers: The final step in using a Sankey chart is to communicate your findings to stakeholders and decision-makers within your organization. This may involve presenting the chart at a meeting or conference, or creating a report that summarizes the key insights and recommendations.
