What is the primary use of estimation in requirements analysis?

Estimation plays a crucial role in requirements analysis, particularly in forecasting costs and efforts. This aspect is vital for effective project planning and resource allocation. By estimating the time, resources, and budget required to fulfill specific requirements, project teams can create more realistic schedules, prioritize tasks, and make informed decisions on project feasibility. This helps stakeholders understand the implications of their requirements on overall project delivery, leading to better planning and management of expectations.

Estimating accurately allows teams to break down complex tasks into manageable components, enabling a clearer view of necessary resources and timelines. This forecasting also aids in risk assessment, helping teams identify potential challenges and adjust their plans accordingly. Therefore, the correct answer highlights estimation's focused role in ensuring that the project can be executed within the defined constraints of time and budget, making it an essential part of the requirements analysis process.
