During which phase of TOGAF ADM are the architecture models developed?

The correct phase during which the architecture models are developed is the Architecture Definition Phase. This phase is critical as it focuses on defining and developing the architecture for the enterprise. It involves the creation of various architecture models that represent the desired architecture across the different domains, including business, data, application, and technology.

During the Architecture Definition Phase, architects take the inputs from the Architecture Vision and begin to elaborate on them, creating detailed models and descriptions that inform the overall architecture. This phase typically results in the production of several artifacts and deliverables that include architecture models, diagrams, and specifications. These documents serve as a foundation for subsequent phases in the architecture development process.

By establishing a clear set of architecture models in this phase, organizations can ensure alignment with business objectives and facilitate effective communication among stakeholders, making it an essential step in the TOGAF ADM process.
