An insight into requirements engineering processes

Abstract

Requirements Engineering (RE) determines the requirements of software according to the needs of customers. Requirements engineering process includes requirements elicitation, requirements modeling, requirements analysis, requirements verification & validation, and requirements management. Among these sub-processes, requirements elicitation plays an important role in extracting the needs of stakeholders, since it is the first requirements engineering sub-process and has cascading effect. It means errors occurring during requirements elicitation will affect the remaining RE processes. Improper understanding of requirements engineering processes may lead to failure of software projects.
