Which phase involves the implementation of the proposed solution?

The phase that involves the implementation of the proposed solution is indeed the indicated option. This phase typically focuses on translating the design and plans developed in earlier phases into working solutions. It encompasses the execution of activities such as coding, testing, and the deployment of the newly created or modified systems or processes that address the identified gaps or needs.

In this phase, stakeholders are actively involved to ensure the proposed solutions are effectively integrated into the existing operational environment. It is crucial for ensuring that the solution meets the defined requirements and achieves the desired outcomes. Successful implementation lays the groundwork for the subsequent phases, which include validating and reviewing the implementations to confirm they meet the objectives set forth in the project.

Understanding this phase is critical for anyone involved in governance, risk management, and compliance processes as it directly links strategic planning with operational execution, reflecting the core principles of effective IT governance as per COBIT.
