Abstract:
At early requirements analysis, resolving conflicts and evaluating design alternatives saves time and effort in the forthcoming phases. Goal oriented approaches are preferred over other requirements engineering approaches for their capability to reason about the requirements and evaluate different solutions. We have enhanced and customized the goal driven reasoning
approach for engineering Web applications. Our work is based upon a standard, User Requirements Notation (URN) that has been enhanced by us to suit the Web applications domain and termed WebURN. For different kinds of Web applications and level of domain knowledge, a suitable reasoning approach i.e. Qualitative or Quantitative can be chosen.We have focused on
qualitative reasoning methodology in this paper, wherein subjective satisfaction values and contribution values are applied
for evaluating the WebGRL graphs. Comparison with other approaches yields that this qualitative approach is more precise,
resolves conflicts automatically and enables choice of design alternatives.
