How does iteration facilitate the development of an integrated architecture?

Iteration plays a crucial role in the development of an integrated architecture by enabling activities across different phases of the Architecture Development Method (ADM) to interact and influence one another. This interaction is essential for ensuring that the architecture is cohesive and meets the evolving requirements of the organization.

In an iterative approach, feedback from one phase can inform and improve the work in another phase, leading to a more adaptable and refined architecture. For example, insights gained during the implementation can be considered in the design phase, and vice versa. This dynamic exchange helps in aligning various architectural components and ensures that they work well together, ultimately contributing to a more integrated and effective architecture.

In contrast, focusing solely on one phase at a time could lead to a disjointed architecture that does not adequately account for dependencies and interactions between phases. Eliminating feedback loops would hinder the ability to learn and adapt, which is essential for addressing changes and challenges. Emphasizing speed over quality can lead to rushed decisions that undermine the overall integrity of the architecture. Therefore, the iterative approach that encourages interaction across phases is key to achieving a well-integrated architecture.
