What should be done with value stream models documented in the Architecture Vision phase?

In the Architecture Vision phase of TOGAF, the documentation of value stream models is crucial for establishing a clear understanding of how value is created and delivered within the organization. Choosing to start with the initial set of documented value streams and assess for new ones is a strategic approach that allows for continual improvement and adaptation.

This option encourages the evaluation of existing value streams in the context of the organization’s goals and objectives. It recognizes that while the initial models provide a foundational understanding, the dynamic nature of business environments often leads to the emergence of new value streams or the evolution of existing ones. By assessing these models, organizations can ensure that they remain relevant and aligned with current business needs, facilitating a proactive approach to value delivery.

The other options lack a comprehensive approach to value stream management. Discarding all previous models could lead to a loss of valuable insights and historical context. Focusing only on previously prioritized streams may overlook new opportunities for value creation. Lastly, limiting consideration to only those value streams identified by senior management disregards the potential insights from broader stakeholders within the organization, who may be aware of other significant value drivers. Therefore, starting with the initial set and assessing for new value streams is key to maintaining a robust and effective enterprise architecture.
