Which of the following could automatically implement changes?

The ability to automatically implement changes largely depends on the use of integrations. When systems and tools are integrated, they can communicate with one another, allowing for the automation of processes, including change implementation. For instance, a change request can be initiated in one tool and then automatically executed in another, without the need for manual intervention. This streamlining reduces the time and effort required to implement changes and minimizes the risk of human error.

In contrast, the other options do not inherently possess the capability to automate change implementation. Manual input requires human action for changes to happen, which contradicts the notion of automation. Email alerts serve as notifications and do not directly lead to executing changes; they inform stakeholders but require manual follow-up. Meetings with stakeholders are vital for discussions and decisions, but they also rely heavily on human participation and cannot automate the implementation of changes. Therefore, the answer that highlights the capability of integration to automate change implementation accurately reflects the process.
