What is the term used to describe the overall structure of components and their inter-relationships within an organization?

The term that accurately describes the overall structure of components and their inter-relationships within an organization is Enterprise Architecture. This concept encompasses the comprehensive framework that defines the architecture of an enterprise, which includes not only the individual components such as processes, information systems, technologies, and personnel but also how they interact with each other.

Enterprise Architecture serves as a blueprint that aligns IT strategy and business goals, facilitating a cohesive integration of various elements within an organization. It enables organizations to understand their structure and processes as well as to plan for changes and improvements.

In contrast, Architecture Domain refers to specific areas of focus within the broader Enterprise Architecture, such as business architecture, information architecture, and technology architecture; it does not encompass the entirety of the organizational structure. A Building Block within TOGAF refers to modular components that can be reused across different parts of the architecture but does not represent the overall structure. Application Architecture specifically addresses the applications and their interactions within the enterprise but is a component of the broader Enterprise Architecture framework. Thus, the term Enterprise Architecture is the most appropriate in capturing the totality of an organization's structure and relationships among its components.
