Requirements analysis is a critical phase in system development where functional and non-functional requirements are gathered from stakeholders to define what the system should do. It serves as the foundation for the system design phase. Why Other Options are Wrong: a) System design focuses on how the system will meet the requirements, not on gathering them. b) Implementation is where the system is built, not where the requirements are specified. c) Maintenance involves updating and fixing the system after deployment. d) Feasibility study assesses the practicality of the project but does not specify requirements.
