A Systematic Approach to Generate and Clarify Consistent Requirements

The development of software systems inevitably involves the detection and handling of inconsistencies. These inconsistencies can arise in system requirements, design specification and quite often in the descriptions that form the final implemented software product. Now days we see requirement engineers focusing their attention to achieve a solid system and user requirements. This involves requirement quality attributes such as completeness, accuracy and consistency of requirements. Basically the starting point of the development of any software system is the requirement engineering phase, projects with inconsistent requirements face problems project containment, the reason for this risk is the difficulty to keep track on requirements during the development, and of course the evolution of descriptions and software requirement specifications without monitoring the changes in the development. Therefore in this paper, we present an approach to increase the degree of requirement consistency in a systematic steps guide the requirements engineer towards generating precise requirements.
