Requirement engineering is the discipline concerned with establishing and managing requirements. It consists of requirements elicitation, analysis, specification, verification, and management.
A requirement is a singular documented need—what a particular product or service should be or how it should perform. It is a statement that identifies a necessary attribute, capability, characteristic, or quality of a system in order for it to have value and utility to a user.
Requirements are derived from operational needs and concepts and are used as inputs to design and development. Requirements are also an important input to verification because tests must trace back to specific requirements to determine if the system performs as intended.
Requirements indicate what elements and functions are necessary for the particular project. The typical phases of requirements development are eliciting, collecting and developing, analyzing and defining, and communicating and managing requirements.
Because of the rapid changes in operational requirements and the pace of technology, increasingly systems engineers face unprecedented levels of uncertainty in developing requirements.
In practice, requirements engineering isn’t so much a sequential process, as it is an iterative process in which activities are interleaved.
Early in the process, most effort will be spent on understanding high-level business and user requirements. Later in the process, more efforts will be spent on elicitation and understanding detailed system requirements.
Typically, requirements are presented into two level of detail; user and system requirements, where user need a high-level statements of the requirements, while system developers need a more detailed system specification. So, user and system requirements are just refer to different level of detail.
Having different level of details is useful because it communicates information about the system being developed for different types of readers.
