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

The correct answer is that the development of Application and Data Architectures occurs during Phase C of the Architecture Development Method (ADM).

Phase C specifically focuses on the design of the architecture focused on the applications required to support the business processes and the data management needs. In this phase, architects define application components, their interactions, and the data structures necessary for effective use within the business architecture. As a result, it serves as a critical stage for ensuring that both the application systems and the data architecture align with the overall goals and requirements identified in the earlier phases of the ADM.

Furthermore, this phase ensures that the applications are appropriately mapped to the architecture that supports the business strategies, placing significant emphasis on business requirements and how data flows through and supports application functionalities. By addressing both application and data architectures in this phase, the foundation is laid for subsequent phases, which will further enhance these elements and ensure they are implemented effectively in the later stages of the ADM.
