Requirements Engineering (ER) is a process that currently is being widely used. It emerged as an improvement of failures during the development of software, since many errors appeared in the final stages of the life cycle. ER can be divided into categories such as functional, non functional and organizational. Its main activities are the elicitation, analysis, specification, validation and management requirements. In the process of development often rely on the activities of the ER, to produce a document of appropriate requirements, which subsequently results in software quality, and this process has inputs and outputs. There are several approaches to develop this same process, however this work, highlighting the spiral model, organizing software development with iterative process. Both actual and future customers and the requirements of engineers are who benefits of this methodology, since there is a reduction of costs, from customers, with better control of the requirements by the engineer and re-use of documentation produced. We focus some tools available in the market, which help the construction of software. There are several techniques for the identification and formulation of requirements, which focus only the methods of the viewpoints requirements oriented, providing an example of practical application. There are ethics issues in Requirements Engineering with particular emphasis on competence, confidentiality, and intellectual property rights and data protection.
