What is the relationship between architectures at different levels?

The correct answer underscores the interconnected nature of architectures at different levels within an organization. In enterprise architecture, levels of architecture—such as business, information, application, and technology architecture—are not standalone entities. Instead, they exist within a governance framework that aligns them with the organization’s overall strategy and objectives.

This hierarchical relationship is essential for ensuring coherence and consistency across all architectural layers. It allows for effective decision-making, resource allocation, and prioritization, enabling the organization to respond effectively to changes in the business environment. Governance ensures that all architecture levels are aligned with each other, supporting integration and collaboration rather than isolation.

While architectures may have distinct responsibilities and focus areas, they depend on each other to create a holistic view of the enterprise. This interconnectedness facilitates communication and helps address cross-functional challenges, ultimately leading to improved performance and outcomes.
