Explanation
Escalating and communicating to stakeholders the risk and mitigating it by allocating additional resources or extending the timeline of the project to support the new requirement based on stakeholders' input are two actions that should be performed to mitigate the risk. These actions help to manage the scope change and ensure that the project is delivered with the expected quality and functionality.

Explanation
Creating transparency by being honest and clear about timing, planning, and obstacles is one of the Scrum principles, as it helps to build trust and collaboration among the team and the stakeholders. Delivering working software is also a Scrum principle, but it does not mean that the software should not be changed if it is working. Respect is another Scrum principle, but it does not imply that a developer should not test the software, as testing is part of the development process. Embracing change is also a Scrum principle, but it does not mean that the scope should change every day, as that would make it impossible to deliver value and quality.

Explanation
A product owner is responsible for defining the scope and prioritizing the backlog of the project. A product owner can help the COE manage the scope creep between the different projects by aligning the business goals and ensuring the value delivery. A scrum master, a release manager, and a change manager are not directly involved in scope management.

Explanation
The Metadata API is mainly used for file-based deployment, such as deploying an application from a Developer Edition org to the AppExchange, or from a sandbox org to a production org. The Ant Migration Tool is a wrapper around the Metadata API, so it is not a direct use case for writing code to call retrieve() and deploy() methods. The Salesforce CLI (SFDX) uses the Source-Driven Development model, which relies on the source code as the source of truth, rather than the Metadata API.

Explanation
Using continuous integration with automation testing is a development practice that will help to reduce the amount of bugs, as it allows the code to be built and tested frequently and automatically. Encouraging the development team to do peer code review is a development practice that will help to reduce the amount of bugs, as it allows the code to be checked and improved by other developers. Incorporating test-driven development into the project structure is a development practice that will help to reduce the amount of bugs, as it requires the developers to write tests before writing code and ensure that the code meets the test criteria.
Enabling the development team to be self-organizing is not a development practice that will help to reduce the amount of bugs, as it does not directly affect the quality of the code. Enabling a short and timely feedback loop with customers is not a development practice that will help to reduce the amount of bugs, as it does not directly affect the quality of the code.
