Most Web applications are designed in an ad-hoc manner. Web applications, due to their peculiar nature, cannot be just developed as conventional software projects. Haire et al advocate Web OPEN [1] [2], extension to OPEN (Object-oriented Process, Environment, and Notation), as suitable model and provide a good study on it. We however, argue Web OPEN does address some of the peculiar issues of Web applications but not all, which we identify in this paper. We then propose a hypothesis that Web OPEN can be augmented in its efficacy with integration of components from other methodologies. In this paper we have investigated such components that could serve our hypothesis. We name the new model as Web OPEN Integrated.
