Which tasks are involved in requirements analysis and design definition?

The tasks involved in requirements analysis and design definition primarily focus on understanding and refining the needs of stakeholders and establishing a clear set of requirements for potential solutions. In this context, modeling, validating, and estimating solution options is critical because it allows analysts to visually represent the requirements, validate them with stakeholders to ensure they align with business needs, and assess the feasibility of various solutions.

Modeling involves creating diagrams or models that illustrate how the system should behave and how its components will interact. This helps in visualizing requirements and facilitates better communication among stakeholders. Validating ensures that the requirements meet the actual needs of the users and the business, which is essential for successful project outcomes. Estimating solution options includes assessing resources, timelines, and costs associated with the implementation of different solutions, which helps in making informed decisions on which path to take.

The tasks associated with creating marketing strategies, developing user interface prototypes, and conducting market research, while important in their respective areas, do not directly contribute to the requirements analysis and design definition phase. They are more aligned with product positioning, design implementation, and understanding market trends, rather than specifically focusing on eliciting, analyzing, and defining requirements for a project. Thus, the choice that encompasses the core activities of this critical phase
