To map your value chain, identify the activities contributing to your product or service delivery, from raw material sourcing to customer distribution. Assess the inputs, outputs, and impacts of each activity, including environmental and social aspects. Engage with stakeholders to gather relevant data, then create a visual representation highlighting value creation points, risks, and improvement opportunities. This helps in understanding the full scope of operations and identifying potential sustainability initiatives. Regularly update the map to ensure accuracy and relevance, and use it to inform decision-making and strategy development.
