In order to guarantee effective system development, requirements analysis is a crucial stage in the system engineering process that focuses on comprehending, recording, and managing the needs and expectations of stakeholders. The main points and importance of requirements analysis in system engineering are summarised in this abstract. In order to specify the intended system behaviour and features, requirements analysis is introduced as a systematic method of collecting, analysing, and prioritising needs in the abstract. In order to enable efficient system design, development, and deployment, it emphasises the need of extensive requirements analysis. The basic goals of requirements analysis are also covered in the abstract, including stakeholder identification, requirement elicitation and documentation, dispute resolution, and requirement traceability and verifiability. It emphasises the importance of requirements analysis in ensuring that the system complies with user requirements, legal requirements, and practical limitations.
