System requirements typically fall into five general categories: functional requirements, non-functional requirements, interface requirements, constraints, and performance requirements.

Functional requirements define what a system should do, outlining the specific functions or actions that the system must perform to fulfill user needs. Non-functional requirements, on the other hand, describe how a system should perform its functions, focusing on aspects like reliability, usability, and efficiency. Interface requirements specify how different system components interact, including user interfaces and external systems. Constraints are limitations or conditions that the system must operate under, such as regulatory standards or technology limitations. Finally, performance requirements detail the expected speed, responsiveness, and efficiency of the system under specific conditions.

Understanding these categories is crucial for system analysts as they guide the development process, ensuring that all necessary aspects of the system are considered and properly documented. This categorization helps teams prioritize and address specific stakeholder needs effectively, leading to a successful system design and implementation.
