For over a decade, dedicated E-markets have been facilitating globally distributed systems development by enhancing the traditionally high-risk global sourcing processes. At the same time, the success and potential of E-markets for sourcing project globally can be questioned, as E-markets embody a variety of temporal, geographical and socio-cultural gaps. To study the effectiveness of the mechanisms offered by the E-markets, we ran a field experiment in which four development teams worked for 10 weeks to have a software development product designed, programmed and tested by remote developer(s) using an E-market. Three out of the four teams managed to deliver a successful product within time and budget. This result exceeded our expectations and contradicts the critical observations and opinions in several blogs and news articles. We find that for effective e-Market sourcing a skilled customer team with competences including vendor selection, software contracting, software requirements specification, development methods, cross-cultural and virtual communications, use of various cloud based tools, frequent functional and non functional testing are necessary.

The considerations presented in this position paper provide a starting point for incorporating model representations on additional perception channels, e.g., by using audio, into the concrete syntax specification of modeling languages. As it turns out, this cannot be done inside the frameworks of existing concrete syntax specification approaches, but first means to question the state-of-the-art of treating concrete syntax definitions as static mapping structures, and subsequently requires to widen the understanding of what concrete syntax is to an operative view on how humans interact with models.

Whether or how firms can employ the halo effect to facilitate their mobile payment service adoption remains a critical and puzzling issue in e-commerce research. Using the schema theory and the value literature as theoretical lenses, this study investigates the role of halo effect on mobile payment value perceptions and usage intentions. More specifically, we identify two types of mobile payment value: utilitarian and hedonic value. A field survey with 273 responses is conducted to test the research model and hypotheses. Our findings show that the two factors of the web-mobile payment relationship, namely perceived similarity and perceived business tie, can lead to increased value perceptions of mobile payment. Moreover, both utilitarian value and hedonic value are positively associated with mobile payment usage intention. We expect this study can provide valuable insights regarding the significant role of halo effect when consumers make the decision to use mobile payment services. Limitations, theoretical and practical implications are also discussed.

The paper describes a, framework and implementing issues addressing service orientation in the management and control of enterprises. A hybrid, semi-heterarchical control model based on the paradigm of holonic manufacturing is proposed;it switches its operating mode from hierarchical to heterarchical in the presence of perturbations to ensure both global optimization and agility to changes in batch orders, while featuring robustness to disturbances in the production environment. In order to ensure these conflicting functionalities, a service oriented architecture is proposed and implemented, whose structure includes a distributed fault-tolerant Resource Service Access Model. Besides the design of a generic structural and dynamic model, a real implementation solution is proposed using a multi-agent framework.

Modern high-performing software product development organizations are nowadays more and more often transforming their operations towards continuous higher-level ends. In general, customer satisfaction (CS) is such a goal. This paper presents an approach of gauging and improving customer satisfaction in an industrial B2B product development project organization for continuous customer experience (CX) management. In order to do that, the Customer Satisfaction Index (CSI) used in the company was systematized with an applied impact analysis technique. The resulting artifact (called CSI Impact Mapping Grid) combines a set of satisfier improvement strategies derived from our initial work with the GQM+Strategies method coupled with the company assets (capabilities) and insights. It is furthermore aimed to be integrated with rich online measurement inputs for real-time predictive feedback. Such transparency across the whole organization enables employees to realize and insightfully support - even proactively in real time - the various cause-effect relationships of the CS/CX.

Much of the research on Performance Management (PM) for collaborative enterprises (CE) is based on qualitative considerations and does not consider the impact of modern information Systems both on the collaborative/competitive dimension of firms and on the PM process. The peculiarities of the different types of CEs are not clearly addressed and managed in literature, and the performance measurements are often oriented to specific aspects rather than to assess the overall quality of business. Moreover, in several proposals, the skills and the time required to the managers of CEs are far from those available in the largest part of existing SMEs. In this scenario the objective of the paper is to discuss how conceptual modeling techniques, and namely ontologies and performance modeling, can contribute to better manage collaborative enterprises.

Technical debt represents the situation in a project where developers accept compromises in one dimension of a system in order to meet urgent demands in other dimensions. These compromises incur a "debt", on which "interest" has to be paid to maintain the long-term health of the project. One of the elements of technical debt is documentation debt due to under-documentation of the evolving system. In this exploratory study, our goal is to examine the different aspects of developers' motivation to document code. Specifically, we aim to identify the motivating and hindering aspects of documentation as perceived by the developers. The motivating aspects of code documenting we find include improving code comprehensibility, order, and quality. The hindering aspects include developers' perception of documenting as a tedious, difficult, and time consuming task that interrupts the coding process. These findings may serve as a basis for developing guidelines toward improving documentation practices and encouraging developers to document their code thus reducing documentation debt.

The use of lean software development methodology and business model experimentation has become popular in software companies in recent years. business model experimentation is used to validate assumptions made on a product from real customers before the actual product is created. A minimum viable product is used to test the business model by gathering and measuring customer feedback. However, in many cases creating a minimum viable product requires the development team to take shortcuts and workarounds in the product. This phenomenon in software development is called 'technical debt', where companies trade long-term software quality to short-term gain in time-to-market. We investigated four software companies and conducted nine interviews to understand the relationship between business model experimentation and technical debt. The goal was to study how business model experimentation is affecting to technical debt. The results showed that business model experimentation has a clear relationship to technical debt.

Data Integration (DI) is the problem of combining a set of heterogeneous, autonomous data sources and providing the user with a unified view of these data. Integrating data raises several challenges, since the designer usually encounters incompatible data models characterized by differences in structure and semantics. One of the hardest challenges is to define correspondences between schema elements (e.g., attributes) to determine how they relate to each other. Since most business data is currently stored in relational databases, here present a declarative and formal approach to specify 1-to-1, 1-m, and m-to-n correspondences between relational schema components. Differently from usual approaches, our (CAs) have semantics and can deal with outer-joins and data-metadata relationships. Finally, we demonstrate how to use the CAs to generate mapping expressions in the form of SQL queries, and we present some preliminary tests to verify the performance of the generated queries.
