Which of the following is the final step in the development of the four architecture domains?

The final step in the development of the four architecture domains is to create the Architecture Definition Document. This document serves as a crucial artifact that encapsulates the architecture that has been developed across the domains of business, data, application, and technology. It provides a comprehensive view of the architecture along with the necessary details that define and describe the architecture vision, principles, requirements, and the specific models and diagrams created during the architecture development process.

Creating the Architecture Definition Document is an essential part of ensuring that all stakeholders have a clear understanding of the architecture and its components. It acts as a foundational reference for the implementation of the architecture, linking the domains together and ensuring consistent communication regarding the architectural decisions made throughout the development process.

This step comes after the necessary analyses, such as performing Gap Analysis and conducting a formal stakeholder review, which help identify discrepancies and gather feedback from stakeholders. Selecting reference models, viewpoints, and tools is also part of the earlier phases of the architecture development process, necessary for shaping how the architecture will be defined. Therefore, the creation of the Architecture Definition Document effectively concludes the development phase by synthesizing all prior work into a structured and formalized document.
