“…In the real case described, the level of detail of requirements may serve both as input for a systematic Web and hypermedia design [1,13] and for more informal approaches to Web design [20].…”

“…We used a systematic Web design technique (called W2000 [1,16], an evolution of HDM [14]) for elaborating design solutions on the basis of the requirements. W2000 is a schema-based conceptual design model for Web applications that-similarly to a variety of other design models-offers conceptual constructs to define the information design, the navigation design, the publishing design, and the operation design.…”

“…Navigation-based user experiences such as accessing product catalogues, locating needed content, freely exploring product information, navigating to related products, and changing site department are blended with operationoriented tasks such as putting a product in the shopping bag, starting a purchase process, providing authentication info, setting a payment method, setting shipping and billing address, and confirming the order. It has been acknowledged that the blending of these paradigms poses new challenges for the design of the user experience [1].…”

Requirements analysis for Web applications still needs to employ effective RE practices to accommodate some distinctive aspects: capturing high-level communication goals, considering several user profiles, defining hypermedia-specific requirements, bridging the gap between requirements and Web design, and reusing requirements for an effective usability evaluation. Techniques should be usable, informal, require little training effort, and show relative advantage to project managers. On the basis of the i * framework, this paper presents a proposal for defining hypermedia requirements (concerning aspects such as content, interaction, navigation, and presentation) for Web applications. The model adopts a goal-driven approach coupled with scenario-based techniques, introduces a hypermedia requirement taxonomy to facilitate Web conceptual design, and paves the way for systematic usability evaluation. Particular attention is paid to the empirical validation of the model based on the perceived quality attributes theory. A case study developed with industrial partners is discussed.

“…Among more recent projects, WebML is closer to those based on conceptual methodologies like W2000 [Baresi et al 2000] and OO-HMETHOD [Gómez et al 2001] (based on UML interaction diagrams), Araneus [Mecca et al 1999;Merialdo et al 2003], Strudel [Fernandez et al 1998] and OO-HDM ]. With less emphasis on modeling, Weave [Yagoub et al 2000] focused on Web site performance.…”

While Web applications evolve towards ubiquitous, enterprise-wide or multi-enterprise information systems, they face new requirements, such as the capability of managing complex processes spanning multiple users and organizations, by interconnecting software provided by different organizations. Significant efforts are currently being invested in application integration, to support the composition of business processes of different companies, so as to create complex, multi-party business scenarios. In this setting, Web applications, which were originally conceived to allow the user-to-system dialogue, are extended with Web services, which enable system-to-system interaction, and with process control primitives, which permit the implementation of the required business constraints. This paper presents new Web engineering methods for the high-level specification of applications featuring business processes and remote services invocation. Process-and service-enabled Web applications benefit from the high-level modeling and automatic code generation techniques that have been fruitfully applied to conventional Web applications, broadening the class of Web applications that take advantage of these powerful software engineering techniques. All the concepts presented in this paper are fully implemented within a CASE tool.

“…This study focuses on web applications as Management Information Systems (MIS) accessed via a web browser with a central database backend. It focuses on the following definition of a web application proposed by [2]: "These new web applications blend navigation and browsing capabilities, common to hypermedia, with 'classical' operations (or transactions), common to traditional information systems". This study does not consider in its scope E-Commerce sites, informational sites, online communities or web portals.…”

Abstract. This paper explores the software processes and usability techniques used by Small and Medium Enterprises (SMEs) that develop web applications. The significance of this research is that it looks at development processes used by SMEs in order to assess to what degree usability is integrated into the process. This study seeks to gain an understanding into the level of awareness of usability within SMEs today and their commitment to usability in practice. The motivation for this research is to explore the current development processes used by SMEs in developing web applications and to understand how usability is represented in those processes. The background for this research is provided by the growth of the web application industry beyond informational web sites to more sophisticated applications delivering a broad range of functionality. This paper presents an analysis of the practices of several Irish SMEs that develop web applications through a series of case studies. With the focus on SMEs that develop web applications as Management Information Systems and not ECommerce sites, informational sites, online communities or web portals. This study gathered data about the usability techniques practiced by these companies and their awareness of usability in the context of the software process in those SMEs. The contribution of this study is to further the understanding of the current role of usability within the software development processes of SMEs that develop web applications.
