Software requirement engineering

when we want to construct a software, need to determine goal of this developing. The goal of a software designing is based on requirements that we want to manage and answering them. Users can tell us about their requirements and we must analyze them to extract processes for developing software. But collecting user interview’s and describes is not enough. A software engineer must captures requirements and extracts a model to construct a useful product. Requirement capture is a very important step in software development process and a software engineer with deep knowledge about this step can do it. Because of bold role of this concept, software requirement engineering is a wide area for research and development that means the manners to notice requirements, capture them, extract a requirement model an using it in nextsteps. In this paper we explain about concept of software requirement engineering in several methods of software development process and comparing them.
