Análise de técnicas de modelagem e especificação de requisitos

Abstract

In the software development process, requirements are one of the most important elements, because no other part of the project is so difficult to correct and detrimental to the resulting system if done incorrectly. Software requirements define what a system should do, but without describing how it should be done. Are the system functions, features and properties. Focusing on the problem of modeling and documentation of requirements, organizations, mostly, have great difficulty in identifying and adopting an appropriate model to perform the requirements specification and end up generate incomplete or illegible documentation, because the models used are not appropriate to the project type or organization shape. A model must establish the operating characteristics and the system behavior. Is through a model that a software is created, because this facilitates the understanding of the project. Thus, there is a crucial need in choosing a suitable process for modeling and requirements specification. This work intends to present, analyze and compare several techniques for modeling requirements with examples of their documentation, pros and cons using a descriptive and comparative research, in the descriptive studies form based on bibliographic research. Allowing the reader to know a range of modeling techniques and the most appropriate formats for each type of project
