Requirement engineering: a bedrock for information systems construction

Abstract

The signs of the increasing use of information technology by several segments of society, as a definitive component of their activities, allied to the complexity of the proposed solutions for the day-today issues, brought a new subject within Software Engineering, called Requirement Engineering. This paper details the reasons for the irreversible use of this subject in the process of information systems development. Some numbers are presented to point the most probable factors for IT project failures. The main Requirement Engineering features, its usage and its evolution are presented as well.
