Question:
The purpose of the requirements determination is to capture a clear and high-level explanation of the system and user requirements stated in the systems request. The explanation consists of a very detailed list of requirements that can be used as input to the analysis phase, which requirements lead into the design of a system.
Requirements that focus on business user needs are called business requirements and sometimes user requirements. In the design phase, business requirements evolve into technical requirements, and they describe how a system will be implemented.
Requirements can be functional or nonfunctional. A functional refers to a process the system has to perform or information it needs to contain. Nonfunctional refers to system properties such as performance and usability. Requirements are gathered in a report called requirements definition stating all functional and nonfunctional requirements in a text form. An effective way to gather requirements is to jointly have business users and analyst to elicit requirements.
There are several techniques to gather requirements such as one-to-meetings, JAD sessions, observation, questionnaires, and prototyping. During requirement meetings, the analyst will ask open or close-ended questions for requirements gathering.
