A value stream is an approach to modeling business value that focuses on the end-to-end sequence of activities that an organization performs to deliver a product or service to the customer. This perspective is designed to help organizations understand the full lifecycle of value creation, from the initial customer demand to the final delivery of value. It provides a holistic view of the flow of value through the organization and is instrumental in identifying areas of waste and opportunities for improvement to enhance the overall customer experience. Value streams help in visualizing and optimizing the steps necessary to effect change in the business processes and systems that create value for the customers.
