,Requirements engineering
Requirements Engineering is the process of
identifying, eliciting, analyzing, specifying, validating, and
managing the needs and expectations of stakeholders
for a software system.
Software requirements are descriptions of the features,
functions, capabilities, and constraints that a software
system must possess to meet the needs of its users and
stakeholders.
They serve as the foundation for software development,
guiding the design, implementation, and testing phases
of the project

, Software Requirements
According to IEEE Standard 729:
A condition or capability needed by a user to
solve a problem or achieve an objective.
A condition or capability that must be met or
possessed by a system (or component) to
satisfy a contract, standard, or specification.
A documented representation of such
conditions or capabilities.
