The waterfall software development life cycle is a methodology that divides the project into phases, and the project manager focuses on control of time, cost, and scope. The waterfall model is a linear and sequential approach that follows a predefined set of steps from the initiation to the closure of the project. The waterfall model assumes that the requirements, scope, and design of the project are clear and stable, and that each phase can be completed before moving to the next one. The waterfall model helps to ensure that the project deliverables meet the quality standards and specifications, and that the project is completed within the budget and schedule12. The spiral software development life cycle is a methodology that combines the iterative and incremental approach with the risk management and prototyping techniques. The spiral model is a cyclical and evolutionary approach that follows a series of loops or iterations from the planning to the deployment of the project. The spiral model assumes that the requirements, scope, and design of the project are dynamic and complex, and that each iteration can be refined and improved based on the feedback and learning from the previous ones. The spiral model helps to identify and mitigate the risks and uncertainties of the project, and to deliver a functional and adaptable product13. The agile software development life cycle is a methodology that emphasizes the collaboration, communication, and flexibility among the project stakeholders. The agile model is an adaptive and iterative approach that follows a series of short and frequent cycles or sprints from the conception to the delivery of the project. The agile model assumes that the requirements, scope, and design of the project are emergent and changing, and that each sprint can deliver a working and valuable product increment. The agile model helps to respond to the changes and feedback of the project, and to maximize the customer satisfaction and value14. The incremental software development life cycle is a methodology that breaks down the project into smaller and manageable chunks or modules. The incremental model is a progressive and modular approach that follows a series of steps from the analysis to the implementation of each module of the project. The incremental model assumes that the requirements, scope, and design of the project are partially known and defined, and that each module can be developed and delivered independently. The incremental model helps to reduce the complexity and risk of the project, and to provide a gradual and continuous delivery of the product15. References:

Verification is the process of evaluating the stated requirements to ensure that they are well-formed, consistent, complete, correct, and aligned with the organizational standards for business analysis. Verification is usually done by the BA or a peer reviewer before presenting the requirements to the stakeholders for validation or acceptance. Verification helps to ensure the quality and accuracy of the requirements, and to avoid errors, ambiguities, or misunderstandings. The other options are not the states that the BA is attempting to move the requirements into, as they are more related to the evaluation of the requirements against the business need, stakeholder expectations, or solution design. References: CBAP Handbook, CBAP Study Guide, BABOK Guide

Tracing requirements is a task that involves identifying and documenting the relationships among requirements, stakeholders, solution components, and other artifacts. Tracing requirements can help the BA to discover the issues of missing or unsupported functionality, as it allows the BA to track the origin, allocation, dependencies, and impact of each requirement. By tracing requirements, the BA can ensure that the requirements are aligned with the business need and objectives, and that they are implemented and verified in the solution. The other options are not the tasks that the BA used to discover the issues, as they are more related to the definition, elicitation, or evaluation of the requirements, rather than the tracing of the requirements. References: Task: Trace Requirements, CBAP / CCBA Certified Business Analysis Study Guide, 2nd Edition, BABOK Guide
