Explanation
Quality function deployment (QFD) is a technique that involves translating customer needs or requirements into product features or specifications. QFD helps to relate the product features to customer value by using a matrix called a House of Quality, which shows how each feature satisfies a customer requirement, how important each requirement is to the customer, how well each feature performs compared to competitors, and how each feature affects other features. QFD can also help to identify gaps or opportunities for improvement in the product design. References: = PMI Professional in Business Analysis (PMI-PBA)

Explanation
A traceability matrix is a document that the business analyst can use to determine the relationship of each requirement to the business need when working on Project Y. A traceability matrix is a table that shows how each requirement relates to other project artifacts, such as business needs, objectives, deliverables, design elements, test cases, or risks. A traceability matrix can help to ensure that each requirement is aligned with and contributes to the business need that initiated the project. It can also help to verify that each requirement is necessary, feasible, testable, and traceable throughout the project life cycle. A traceability matrix can also help to manage changes and measure progress in relation to the business need. A requirements baseline document is a version of the requirements specification that has been reviewed, approved, and formally established as the basis for further development and delivery of the solution. A requirements baseline document defines the scope of the project and the expected value of the solution. It does not show how each requirement relates to the business need explicitly. A requirements management plan is a document that describes how requirements will be elicited, analyzed, documented, validated, and managed throughout the project. A requirements management plan defines the roles, responsibilities, processes, and tools for managing requirements. It does not indicate the relationship of each requirement to the business need specifically. A requirements package is a document that presents the requirements in a structured and organized way for communication and verification purposes. A requirements package may include different types of requirements, such as functional, non-functional, quality, or transition requirements. It does not demonstrate how each requirement relates to the business need directly. A reliability matrix is not a standard document in business analysis, but it may refer to a tool that measures the reliability or dependability of a system or a process. A reliability matrix evaluates the performance or quality of a solution. It does not determine the relationship of each requirement to the business need.

Explanation
The project life cycle is a key factor that drives the selection of business analyst activities to be included in the project. The project life cycle is the sequence of phases or stages that the project goes through from initiation to closure. The project life cycle can be selected based on various factors, such as the nature, complexity, size, and uncertainty of the project, the stakeholder preferences, the organizational culture, and the industry standards. The project life cycle can influence the approach that the business analyst and the project team use to plan, execute, monitor, and control the project, and to deliver the product or service. The project life cycle can also affect the type, level, and timing of the business analysis activities, such as elicitation, analysis, documentation, validation, and management of the requirements.

Explanation
According to the PMI Professional in Business Analysis objectives and content, a vision/scope document is a document that describes the high-level vision, scope, and objectives of a project or initiative. It also defines the key stakeholders, business needs, expected benefits, assumptions, constraints, and risks. A vision/scope document can help to align the stakeholders' views of organizational improvement with the project's purpose and direction. It can also help to establish a common understanding and agreement among the stakeholders, and provide a basis for planning and prioritizing the requirements.

Explanation
The business analyst can determine the impact of a new requirement on existing requirements by reviewing the requirements traceability matrix. The requirements traceability matrix is a tool that tracks the relationships and dependencies among the requirements, as well as other project elements such as design, test cases, risks, or issues. By reviewing the requirements traceability matrix, the business analyst can identify which existing requirements are affected by the new requirement and assess the impact of the change on the scope, schedule, cost, or quality of the project. Performing a stakeholder analysis is not a way to determine the impact of a new requirement on existing requirements, as it focuses on identifying and understanding the needs, expectations, and influence of the stakeholders, not the requirements. Using time-boxing to defer the new requirement is not a way to determine the impact of a new requirement on existing requirements, as it postpones the analysis and implementation of the new requirement until a later iteration or phase of the project. Updating the use case documentation is not a way to determine the impact of a new requirement on existing requirements, as it only reflects how the new requirement affects one aspect of the solution functionality, not the entire project.
