The best way to help ensure new IT implementations align with enterprise architecture (EA) principles and requirements is to conduct EA reviews as part of the change advisory board (CAB). A CAB is a committee that evaluates and authorizes changes to IT services, such as new IT implementations. By conducting EA reviews as part of the CAB process, the organization can ensure that the proposed changes are consistent with the EA vision, goals, standards, and guidelines. This can help avoid potential conflicts, risks, or inefficiencies that may arise from misaligned IT implementations. Additionally, EA reviews can help identify opportunities for improvement, optimization, or innovation in the IT services.
The other options are not the best ways to help ensure new IT implementations align with EA principles and requirements. Documenting the security view as part of the EA is important, but it does not guarantee that new IT implementations will follow the security requirements or best practices. Considering stakeholder concerns when defining the EA is also essential, but it does not ensure that new IT implementations will meet the stakeholder expectations or needs. Performing mandatory post-implementation reviews of IT implementations is a good practice, but it does not prevent potential issues or problems that may arise from misaligned IT implementations.
