Requirements Engineering (RE) is the process of discovering requirements by identifying stakeholders and documenting their requests. A requirement is a feature a product or service must have to be useful to stakeholders. The benefits of a good RE process include reduced rework, faster development, fewer miscommunications, and reduced scope creep. RE involves elicitation, analysis, documentation, communication, and validation of requirements.
