Which of the ADM phases includes the development of Application and Data Architectures?

Phase C of the ADM (Architecture Development Method) within TOGAF specifically focuses on the development of the Data Architecture and Application Architecture. This phase is crucial as it forms the backbone of how data is managed and utilized within an organization, as well as detailing the applications needed to support the business processes.

During Phase C, architects assess the current data capabilities and application landscape, identifying gaps and requirements for the future. This phase integrates with other architectural domains, ensuring that the applications planned can effectively utilize the data that will be structured and managed according to the specifications created. By clearly defining these architectures, organizations can establish a robust foundation for achieving their business goals and ensuring alignment with their overall enterprise architecture.

In summary, Phase C is central to creating a coherent picture of how data and applications will interact and support business objectives, which is why it is the correct choice in this context.
