Measuring Quality Attributes of Web-based Applications Part-I: Assessment and Design

This paper has been designed to predict the Web metrics for evaluating the reliability and maintainability of hyperdocuments. In the age of Information and Communication Technology (ICT), Web and the Internet, have brought significant changes in Information Technology (IT) and their related scenarios. Therefore in this paper an attempt has been made to trace out the Web-based measurements towards the creation of efficient Web centric applications. The dramatic increase in Web site development and their relative usage has led to the need for predicting Web-based metrics. These metrics will accurately assess the effort in a Web-based application. Here we carried out an empirical study with the students of an advanced university class and Web designers that use various client-server based Web technologies to design Web-based applications for predicting the hypermedia design model. Our first goal was to compare the relative importance of each design activity. Second, we tried to assess the accuracy of a priori design effort predictions and the influence of some factors on the effort needed for each design activity. Third, we also studied the quality of the designs obtained based on construction of a User Behavior Model Graph (UBMH) to capture the dynamics involved in user behavior, which is discussed in part-II of this paper. The results obtained from the assessment can help us to systematically identify the effort assessment and failure points in Web systems and makes the evaluation of reliability of these systems simple. The theoretical aspects and designing have been described in part-I. Part-II describes the variation of the effort estimation with the help of analysis and implementation models of Web-based applications.
