Improving the quality of web applications with web specific goal driven requirements engineering

摘要

Requirements Analysis is the most important phase in Software development. It is a known fact now that if this phase is carried out properly the cost and effort of the project can be greatly reduced. Web applications are very important in today's times. Effectively, every organization and even individual has a web application to represent itself. The Web applications have grown from just information providers to full-fledged legacy systems with complex processes. There are various methods of web application development, but hardly any method focuses on detailed requirements analysis that is required owing to the criticality of web applications. Goal oriented requirements engineering techniques have proven to be very effective in requirements analysis. Application of goal driven methodologies for web specific requirements can improve the quality of web applications besides saving cost and effort required in the project. The special characteristics of GORE techniques like analysis of softgoals and interde-pendencies between various requirements help in elimination of conflicts at early stages of web application development. GORE techniques also facilitate evaluation of goal models that helps in choosing amongst the design alternatives and checking completeness of the requirements model leading to Software Requirements Specification. The implementation of web specific goal driven framework is shown in the paper and validated through a usability survey.
