Explanation
Requirements baseline is the approved version of the requirements document that serves as a reference point for further changes. Requirements can be changed after they are baselined through a defined process that involves submitting a change request, analyzing the impact of the change, obtaining approval from the stakeholders, updating the requirements document, and communicating the change to the project team and other affected parties. Requirements can be changed at any stage of the project life cycle as long as they follow the defined process. References: = PMI Professional in Business Analysis (PMI-PBA)

Explanation
According to the PMI Professional in Business Analysis objectives and content, an impact analysis is a technique that is used to assess the effects and implications of a change request on the requirements, scope, schedule, cost, quality, and other aspects of a project or product. An impact analysis can help to determine the feasibility, desirability, and priority of the change request, as well as to identify the risks, issues, and dependencies associated with the change. An impact analysis can also help to communicate the impact of the change to the stakeholders, and to support the decision-making process for approving or rejecting the change request. References:

Explanation
According to the PMI Professional in Business Analysis objectives and content, a prototype is a tool that can be used to elicit, analyze, and validate requirements. A prototype is a representation of a solution that allows stakeholders to interact with it and provide feedback. By developing a prototype, the business analyst can gather functional requirements from the end user and ensure that the new interface supports their core business processes. A prototype can also help to reduce ambiguity, resolve conflicts, and increase stakeholder satisfaction. References:

Explanation
A configuration management system is a tool that can be used to trace the large number of requirements that will be generated by this project. A configuration management system is a system that consists of the processes, procedures, tools, and databases that are used to manage and control the configuration items of the project. A configuration item is any component of the project that has a defined and approved version, such as a requirement, a deliverable, a document, a model, a test case, etc. A configuration management system can help the business analyst and the project team to record, track, update, and maintain the configuration items throughout the project lifecycle, and to ensure their consistency, integrity, and traceability. A configuration management system can also help to handle changes, resolve issues, and measure the quality and performance of the project. References: PMI Professional in Business Analysis (PMI-PBA)

Explanation
The best action to take to ensure the design meets customer requirements is to create a system requirements verification matrix to trace the design to the technical requirements and include verification methods. A system requirements verification matrix is a document that maps the design elements to the system requirements, and specifies the methods and criteria for verifying that the design satisfies the requirements.
Verification methods can include inspection, analysis, demonstration, or testing. A system requirements verification matrix can help the business analyst and the project team to ensure the quality and completeness of the design, and to avoid any errors, gaps, or inconsistencies. : PMI Professional in Business Analysis (PMI-PBA)
