Value stream

A value stream is the set of actions that take place to add value to a customer from the initial request through realization of value by the customer. The value stream begins with the initial concept, moves through various stages of development and on through delivery and support. A value stream always begins and ends with a customer. Value stream is usually aligned with company processes.

Value streams are artifacts within business architecture that allow a business to specify the value proposition derived by an external (e.g., customer) or internal stakeholder from an organization. A value stream depicts the stakeholders initiating and involved in the value stream, the stages that create specific value items, and the value proposition derived from the value stream. The value stream is depicted as an end-to-end collection of value-adding activities that create an overall result for a customer, stakeholder, or end-user.

In modeling terms, those value-adding activities are represented by value stream stages, each of which creates and adds incremental stakeholder value items from one stage to the next.^[1] While value streams are referenced in multiple methodologies, there is increasing agreement^[2] on the description and the purpose of value streams as a core domain of business architecture^[3] and scaled agile framework,^[4] which has since been applied by multiple standards bodies.^[5][6]
