how, and feasibility.A metamodel called 2QCV3Q (in Latin V stands for U),which takes its name from the initials of the Ciceronian loci of classical rhetoric that it is based on [9]. Also called 7Loci, the meta-model takes into special consideration the inherently communicative nature of a Web site [8,10].This concept is used to identify the fundamental dimensions of a Web site, resulting in a framework that when compared with existing models can be seen as a meta-model for classification of diverse criteria for quality (table 1). In other words, the seven loci or dimensions constitute the general framework of the “quality models”, which is independent of the sites under analysis. 1. The first dimension, Identity, regards the image that the organisation projects and therefore all elements that come together in defining the identity of the owner of the site. 2. Content to the information 3. Services refer to the services available for users. 4. Location regards the visibility of a site; it also refers to the ability of the site to offer a space where users can communicate with each other and with the organisation. 5. Maintenance comprises all activities that guarantee proper functioning and operability of the site. 6. Usability determines how efficiently and effectively the site’s content and services are made available to the user. 7. Feasibility includes all aspects related to project management. Table 1. Dimensions of the 2QCV3Q - 7Loci meta-model QVIS(Who?) Identity QVID(What?) Content CVR(Why?) Services VBI(Where?) Location QVANDO(When?) Maintenance QVOMODO(How?) Usability QVIBUS AVXILIIS(With Feasibility what means?) ISO9126 , ISO9241 AND ISO13407 [3,11,12] are very popular software quality standards.ISO9126 , ISO9241 AND ISO13407 describe the standards for quality of software, usability, user-centered product. Conformance to standard is also the basis of W3C quality assurance initiative [13]. The 7Loci meta-model supports a systemic approach to evaluating web site quality that takes into account these diverse components coming together at a site and the importance of satisfying the needs of all actors. A usability-focused evaluation method for hypermedia application is MiLE, based on a combination of inspection from expert evaluator and empirical testing through panels of end users [14]. The evaluation model here is based on two heuristic concepts: abstract and concrete tasks. An analytic web site quality model is proposed by Etnoteam [15].It is based on six attributes :communication, content, functionality, usability, management and accessibility. The model can be personalized.The sub-attributes are weighted depending on the site category. An evolution of this model is described in [16]. Another analytical approach described in [17] proposes a Web-site Quality Evaluation Method based on a logic multi-attribute decision model and procedures intended to be a useful tool to evaluate artifact quality in the operational phase.. Studies for quality of products and processes for the web are very recent and still there are no widely spread evaluation methods and techniques for quality assessment. Fleming 2001[18],Mendes et al. 2001[19], Olsina and Rossi 2001[20], Pooley et al.2002[21] have given the quality attributes and also some of them have evaluated the quality of different web-application domains. The ISO/IEC 9126 series standard introduced a hierarchical model with six major quality characteristics, each very broad in nature . They are subdivided into 27 sub-characteristics, which contribute to external quality, and 21 sub-characteristics which contribute to internal quality. Since the characteristics and subcharacteristics are not properly defined, ISO9126 does not provide a conceptual framework within which comparable measurements may be made by different parties with different views of software quality, such as users, developers and managers. The Authors have given a Quality Evaluation Framework in order to evaluate the quality of Indian ecommerce based web-sites in Section 3. In our previous research, we have validated factors and sub-factors from user’s point of view [25] and
given quality metrics for e-commerce web-sites . 3 Designing the quality evaluation frame work A general model of the evaluation framework is given in figure 2. It shows an initial phase which includes the identification of the evaluation requirements, a design phase in which the evaluation plan and techniques are defined, and a final ranking as per the quality and suggestion phase. I. Quality requirements specification: What is the mission of the web-application. Specify the functional Usability, Functionality and non-functional quality requirements such as Reliability, Efficiency of the webapplications. What is the priority associated with each of the factors. Identify the category of users. web-application users needs vary according to the category of users. Outcome of Figure 1. ISO 9126 Model For Quality this phase is evaluation goals. In designing a web-application developer must see other webapplications having similar objectives. The reason for this is because the users always compare a web application with the other existing applications and uses the most convenient or in other words web-application which has a greater Usability. II. Metrics selection: Select the metrics, their corresponding weights the scale of measurement, and for summation. Outcome of this phase is evaluation plans. III. Measurement: Measurement implementation and result calculation. IV. Result: Ranking of web-applications as per the Global Quality Preference. Suggestions for the evaluated web-application.
