Applying virtual reality for trust-building e-commerce environments

The application of virtual reality in e-commerce has enormous potential for transforming online shopping into a real-world equivalent. However, the growing research interest focuses on virtual reality technology adoption for the development of e-commerce environments without addressing social and behavioral facets of online shopping such as trust. At the same time, trust is a critical success factor for e-commerce and remains an open issue as to how it can be accomplished within an online store. This paper shows that the use of virtual reality for online shopping environments offers an advanced customer experience compared to conventional web stores and enables the formation of customer trust. The paper presents a prototype virtual shopping mall environment, designed on principles derived by an empirically tested model for building trust in e-commerce. The environment is evaluated with an empirical study providing evidence and explaining that a virtual reality shopping environment would be preferred by customers over a conventional web store and would facilitate the assessment of the e-vendor’s trustworthiness.     

A pluggable service platform architecture for e-commerce

In the beginning of the e-commerce era, retailers mostly adopted vertically integrated solutions to control the entire e-commerce value chain. However, they began to realize that to achieve agility, a better approach would be to focus on certain core capabilities and then create a partner ecosystem around them. From a technical point of view, this means it is advised to have a lightweight platform architecture with small core e-commerce functionality which can be extended by additional services from third party providers. In a typical e-commerce ecosystem with diverse information systems of network partners, integration and interoperability become critical factors to enable seamless coordination among the partners. Furthermore an increasing adoption of cloud computing technology could be observed resulting in more challenging integration scenarios involving cloud services. Thus, an e-commerce platform is required that suites the advanced needs for flexible and agile service integration. Therefore, this paper aims to present a reference architecture of a novel pluggable service platform for e-commerce. We investigate on currently available online shop platform solutions and integration platforms in the market. Based on the findings and motivated by literature on service-oriented design, we develop an architecture of a service-based pluggable platform for online retailers. This design is then instantiated by means of a prototype for an e-commerce returns handling scenario to demonstrate the feasibility of our architecture design.

Are software engineers true engineers?

Software engineering is an often used term to describe the activities, methods, and tools of large scale software development. There is an ongoing discussion whether Software Engineering can be considered as an engineering discipline. In many respects the development of software shares common properties of other engineering disciplines. In contrast to “classical” engineering fields, theories, questions, and approaches from the social sciences are more important than those from the natural sciences. This is investigated here by comparing the situation found in software engineering with several concepts of engineering in general. Three viewpoints are used to guide this comparison: one is a social stereotype of engineers; the second is the organization of engineering profession organizations; and the third are capabilities which the engineers of the future will need.

An approach for high-yield requirements capture for e-commerce and its application

Web-based e-commerce software is typically real-time, responsive, and distributed software that must meet high quality requirements. Moreover, because of its Internet-based operating environment, e-commerce software must deal with concurrency, synchronization, and non-deterministic issues (such as delays) primarily caused by the heavy usage load and underlying network conditions. In this paper, we introduce a generic, cost-effective approach to optimize requirements capture (and subsequent development and testing) with respect to functional coverage and customer perception of quality. This high-yield approach is presented and illustrated by application to an e-commerce online shopping system and used to explain the principles of use-case requirements captured in the unified modeling language.

Recommendation agent impact on consumer online shopping: The Movie Magic case study

A simulated online shopping environment with a recommender system based on collaborative filtering data has been developed to empirically test the impact of recommendation agents in an online retail environment. The report provides some background for the most widely used types of recommender system based on collaborative filtering. The Movie Magic system developed for this study is described, as well as the experiment assessing the impact of such an agent on product promotion effectiveness, customer satisfaction with the website, and customer loyalty to the website. Finally, the report discusses the implications of the results for system developers and managers interested in using Intelligent Agent technology for enhancing e-commerce. By corroborating the proposed relationships between the use of the recommender agent and improved product promotion, customer satisfaction and loyalty, the results should aid online businesses in further understanding the benefits and limitations of using a recommender agent to support e-commerce.

Developing Flexible Software Using Agent-Oriented Software Engineering

Software agents are associated with modern industrial software. In various application fields such as e-business, telecommunications, logistics, and industrial automation, software based on agents seems to make the challenges in modern applications easier to overcome. However, it's often unclear what a software agent is and why problems can be better solved with it. Is it concerning a technology, an architecture, or a programming concept? This article presents a general introduction to software agent concepts from the software engineer's perspective, explaining the theoretical basis and clarifying to which type of problem software agents might represent a reasonable approach.     

Developing internet e-commerce benchmarks

A benchmark is a standard for measuring and comparing the performance of like systems. For new product makers, a benchmark can provide important statistical information so products can be fine-tuned before their deployment. For end users, on the other hand, a benchmark can be used to compare the strengths and weaknesses of different products so that an informed decision can be made about system adoption. Benchmarks aid in estimations of scalability in terms of the number of users and/or transactions that a system can support, and system response times under various loads and hardware/software deployment platforms.This paper focuses on the design issues in developing benchmarks for e-commerce. Because of the multidisciplinary aspects of e-commerce and the various emerging and distinct e-commerce business models, creating a single benchmark for the e-commerce application is not feasible. Add to this the diverse needs of small to medium enterprises (SMEs) and big business and we motivate the need for a benchmark suite for e-commerce.It is the thesis of this paper that the business model plays the primary role in the development of a e-commerce benchmark. It is the business that determines processes and transactions and thus also the database and navigational designs. For illustrative purposes, we step through the design of an e-commerce benchmark specification, WebEC, based on a e-broker (cybermediary) Internet business model. An example implementation of the benchmark specification, based on Microsoft's COM technology, and sample benchmark results are also presented.
