In TOGAF's Business Architecture, a value stream stage is a high-level representation of a sequence of activities that create value for an organization. The end state condition denoting the completion of a value stream stage is known as the "Exit Criteria." This term is used to specify the conditions that must be met for the stage to be considered complete, ensuring that the output meets the required quality and performance standards before progressing to the next stage. The concept of "Exit Criteria" is essential to ensure that each stage of the value stream adds the expected value and aligns with the overall business objectives.
