Implementing Cross-Organizational Business Processes with Enterprise Mashups: Hype or Reality?

Many cross-organizational business processes are implemented by hubs and integration platforms which support the electronic collaboration of multiple organizations. The available concepts and solutions based on service-oriented architectures focus on the automatization of long-term business relationships. However, they often do not provide intuitive ways to modify them according to situational needs. In particular, small and medium-sized enterprises characterized by limited know-how and resources are excluded in such electronic collaborations. This paper demonstrates how the user-driven development paradigm of enterprise mashups could be leveraged for implementing cross-organizational business processes. By means of a case study, we report about the experiences of a real-world scenario we have implemented in the frame of the EU-funded research project FAST. A business value analysis highlights the automational, informational and transformational effects. An organized laboratory experiment evaluates how the actual users create enterprise mashups for cross-organizational processes. We conclude with the benefits and limitations of the paradigm

Enhancing User-Service Interaction Through a Global User-Centric Approach to SOA

Considered as enablers of seamless application-to- application integration both within company boundaries and on a global scale, Web Services-based SOAs have traditionally focused on automating service-to-service collaboration. However, they have never featured a "face " to human users. This gap between human users and services still prevents enterprises from realizing how innovations at the SOA front-end help to make people more productive. And, ultimately, it hinders the emergence of a real Web of Services driven by a global, user-centric SOA. In this paper, we revisit the notion of SOA and analyze its major shortcomings with regard to the emergence of a Web of Services enhancing user-service interaction and increased service usability. We then elaborate on novel, currently emerging technologies that facilitate the establishment of the global mesh of interoperable user-centric services. A novel platform architecture is presented that builds on all the key technical enablers

Mining and quality assessment of mashup model patterns with the crowd: A feasibility study

Pattern mining, that is, the automated discovery of patterns from data, is a mathematically complex and computationally demanding problem that is generally not manageable by humans. In this article, we focus on small datasets and study whether it is possible to mine patterns with the help of the crowd by means of a set of controlled experiments on a common crowdsourcing platform. We specifically concentrate on mining model patterns from a dataset of real mashup models taken from Yahoo! Pipes and cover the entire pattern mining process, including pattern identification and quality assessment. The results of our experiments show that a sensible design of crowdsourcing tasks indeed may enable the crowd to identify patterns from small datasets (40 models). The results, however, also show that the design of tasks for the assessment of the quality of patterns to decide which patterns to retain for further processing and use is much harder (our experiments fail to elicit assessments from the crowd that are similar to those by an expert). The problem is relevant in general to model-driven development (e.g., UML, business processes, scientific workflows), in that reusable model patterns encode valuable modeling and domain knowledge, such as best practices, organizational conventions, or technical choices, that modelers can benefit from when designing their own models

Implementation of end-user development success factors in mashup development environments

[EN] The Future Internet is expected to be composed of a mesh of interoperable web services accessed from all over the Web. This approach has been supported by many software providers who have provided a wide range of mash up tools for creating composite applications based on components prepared by the respective provider. These tools aim to achieve the end-user development (EUD) of rich internet applications (RIA); however, most, having failed to meet the needs of end users without programming knowledge, have been unsuccessful. Thus, many studies have investigated success factors in order to propose scales of success factor objectives and assess the adequacy of mashup tools for their purpose. After reviewing much of the available literature, this paper proposes a new success factor scale based on human factors, human-computer interaction (HCI) factors and the specialization-functionality relationship. It brings together all these factors, offering a general conception of EUD success factors. The proposed scale was applied in an empirical study on current EUD tools, which found that today's EUD tools have many shortcomings. In order to achieve an acceptable success rate among end users, we then designed a mashup tool architecture, called FAST-Wirecloud, which was built taking into account the proposed EUD success factor scale. The results of a new empirical study carried out using this tool have demonstrated that users are better able to successfully develop their composite applications and that FAST-Wirecloud has scored higher than all the other tools under study on all scales of measurement, and particularly on the scale proposed in this paper.

Un método de evaluación de usabilidad de mashups basado en la composicionalidad de sus componentes

[ES] Los Mashups son una nueva generación de aplicaciones Web que integran componentes provistos por terceros desde la Web. La usabilidad en este tipo de aplicaciones es un factor muy importante ya que como en toda aplicación Web, este determina el éxito de la aplicación. Si bien se han planteado métodos de evaluación que permiten evaluar la usabilidad de aplicaciones Web en general, éstos no cubren las características inherentes a la composicionalidad de los Mashups. La presente tesina de máster pretende aportar un método de evaluación de la usabilidad de Mashups acorde con sus características propias de composicionalidad. El método está compuesto de un modelo de usabilidad y un proceso de evaluación que provee guías sobre la forma en la que el modelo de usabilidad puede ser usado para realizar evaluaciones específicas. Tanto el modelo de usabilidad como el proceso de evaluación están alineados con el último estándar ISO/IEC 25000 para la evaluación de la calidad de producto (SQuaRE) y ambos toman en cuenta la naturaleza composicional de los Mashups. El modelo de usabilidad descompone el concepto de usabilidad en sub-características y métricas genéricas. Estas métricas son aplicadas en la composición del producto final y el método de evaluación puede ser aplicado en cualquier estado del ciclo de vida de este tipo de aplicaciones, ya sea en la selección de los componentes, durante el proceso de composición o cuando el producto está listo para ser usado. Para apoyar esta propuesta se ha realizado un profundo estudio del estado del arte. Este estudio comprende dos mapeos sistemáticos: el primero abarca un estudio de la evaluación de la calidad de los Mashups y el segundo cubre las características de la composicionalidad envueltas en los Mashups. Los resultados obtenidos aportaron de una forma significativa en la definición del Modelo de Usabilidad de Mashups y posteriormente en el proceso de evaluación de usabilidad. Finalmente, se desarrollaron tres casos de estudio que muestran la viabilidad de nuestro enfoque. Estos casos de estudio muestran en detalle como el método de evaluación propuesto utiliza nuestro Modelo de Usabilidad para Mashups. Los resultados muestran que nuestra propuesta permite detectar problemas de usabilidad, los cuales una vez corregidos, permiten obtener Mashups más usables[EN] Mashups are the new-generation of Web applications that integrates third-party components from the Web. Usability in these applications is very important since their success depends on this quality factor. Although several methods have been proposed to evaluate the usability of Web applications in general, they do not cover the specific characteristics inherent to the compositionality of Mashups. This master thesis aims to provide a method for evaluating the usability of Mashups according to their specific characteristics of compositionality. The method is composed of a usability model and an evaluation process that provides guidelines on how the usability model can be used to perform specific evaluations. Both the usability model and the evaluation process are aligned with the latest ISO/IEC 25000 standard for software product quality evaluation (SQuaRE), and both take into account the compositional nature of mashups. The usability model breaks down the concept of usability into sub-characteristics, attributes and generic metrics. These metrics are applied to the final product composition and process evaluation method can be applied at any stage of the life cycle of this kind of applications (i.e., during the component selection, the composition process or when the product is ready for use. In order to support the foundation of this proposal, an in-depth study was performed about the state of art. This study comprises two systematic mappings: the first one covers the quality evaluation of Mashups, whereas the second one covers the compositionality features involved in Mashups. The obtained results were used as input in order to define both our Mashups Usability Model, and our usability evaluation process. Finally, we developed three case studies in order to show the feasibility of our approach. These case studies show in detail how the proposed evaluation method was followed by using our Mashup Usability Model. Results showed that our approach was able to detect usability problems, which once corrected, it allows obtaining more usable Mashups.Cedillo Orellana, IP. (2013).
