Explanation
A traceability matrix is a document that links requirements to their sources and traces them throughout the project life cycle. It helps to track changes in requirements, assess their impact, and ensure that they are met by the project deliverables. A traceability matrix is a useful tool for document control, as it records the version history of each requirement and the rationale for any changes. A statement of work, a project plan, and a problem or opportunity statement are not methods of document control, but rather documents that describe the project scope, objectives, activities, and justification.

Explanation
A closed-ended survey using the Likert scale is a type of survey that asks respondents to indicate their level of agreement or disagreement with a series of statements related to the current business process. This type of survey is useful for gathering data that can be used in a statistical analysis to measure user satisfaction, identify pain points, and evaluate the performance of the current business process. A closed-ended survey is also easier to administer and analyze than an open-ended survey, which requires more time and effort to code and interpret the responses.
