- ZeitschriftenartikelImplementation of Aspect-oriented Business Process Models with Web Services(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Jose, Hercules Sant Ana da Silva; Cappelli, Claudia; Santoro, Flavia Maria; Azevedo, Leonardo GuerreiroIn software development, crosscutting concerns, such as security, audit, access control, authentication, logging, persistence, transaction, error handling etc. can be modularized using the aspect-oriented paradigm. In business process modeling, aspects have been used to reduce visualization complexity, increase reuse and improve model maintainability. There are techniques which address aspects in modeling and implementation phases of business process; however, these techniques adopt different semantic representations, hindering the integration of these phases into the BPM lifecycle. This work proposes an architecture for service discovery capable of selecting web services that implement crosscutting concerns and meet the goals established in the aspect modeling phase, executing them accordingly with a prioritization. A proof of concept to analyze the proposed architecture and generated artifacts was performed. Afterwards, the proposal was evaluated by means of an experiment. The results suggest that the definition of an operational goal enables the business specialists to concentrate on the modeling of the aspect without necessarily concerning its implementation, since a proper option for implementation is discovered during the execution of the process.
- ZeitschriftenartikelA Case for a New IT Ecosystem: On-The-Fly Computing(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Karl, Holger; Kundisch, Dennis; Meyer auf der Heide, Friedhelm; Wehrheim, HeikeThe complexity of development and deployment in today’s IT world is enormous. Despite the existence of so many pre-fabricated components, frameworks, cloud providers, etc., building IT systems still remains a major challenge and most likely overtaxes even a single ambitious developer. This results in spreading such development and deployment tasks over different team members with their own specialization. Nevertheless, not even highly competent IT personnel can easily succeed in developing and deploying a nontrivial application that comprises a multitude of different components running on different platforms (from frontend to backend). Current industry trends such as DevOps strive to keep development and deployment tasks tightly integrated. This, however, only partially addresses the underlying complexity of either of these two tasks. But would it not be desirable to simplify these tasks in the first place, enabling one person – maybe even a non-expert – to deal with all of them? Today’s approaches to the development and deployment of complex IT applications are not up to this challenge. “On-The-Fly Computing” offers an approach to tackle this challenge by providing complex IT services through largely automated configuration and execution. The configuration of such services is based on simple, flexibly combinable services that are provided by different software providers and traded in a market. This constitutes a highly relevant challenge for research in many branches of computer science, information systems, business administration, and economics. In this research note, it is analyzed which pieces of this new “On-The-Fly Computing” ecosystem already exist and where additional, often significant research efforts are necessary.
- ZeitschriftenartikelThe Impact of Integration on Application Success and Customer Satisfaction in Mobile Device Platforms(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Bender, BenedictDigital software platforms allow third parties to develop applications and thus extend their functionality. Platform owners provide platform boundary resources that allow for application development. For developers, platform integration, understood as the employment of platform resources, helps to realize application functionality effectively. Simultaneously, it requires integration effort and increases dependencies. Developers are interested to know whether integration contributes to success in hypercompetitive platform settings. While aspects of platform participation have been studied, research on a comprehensive notion of integration and related implications are missing. By proposing a platform integration model, this study supports a better understanding of integration. Concerning dynamics related to integration, effects were tested using information from over 82,000 Apple AppStore applications. Regression model analysis reveals that application success and customer satisfaction is positively influenced by platform integration. To achieve superior results, developers should address multiple aspects of integration, such as devices, data, the operating system, the marketplace as well as other applications, and provide updates. Finally, the study highlights the importance for all platform participants and their possibilities to employ integration as a strategic instrument.
- ZeitschriftenartikelThe Energy Consumption of Blockchain Technology: Beyond Myth(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Sedlmeir, Johannes; Buhl, Hans Ulrich; Fridgen, Gilbert; Keller, RobertWhen talking about blockchain technology in academia, business, and society, frequently generalizations are still heared about its – supposedly inherent – enormous energy consumption. This perception inevitably raises concerns about the further adoption of blockchain technology, a fact that inhibits rapid uptake of what is widely considered to be a groundbreaking and disruptive innovation. However, blockchain technology is far from homogeneous, meaning that blanket statements about its energy consumption should be reviewed with care. The article is meant to bring clarity to the topic in a holistic fashion, looking beyond claims regarding the energy consumption of Bitcoin, which have, so far, dominated the discussion.
- ZeitschriftenartikelDesigning for Crowdfunding Co-creation(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Lipusch, Nikolaus; Dellermann, Dominik; Bretschneider, Ulrich; Ebel, Philipp; Leimeister, Jan MarcoCrowdfunding is now established as a valid alternative to conventional methods of financing for startups. Unfortunately, to date, research has not investigated how backers can be encouraged to support entrepreneurs beyond funding. The aim of this study is to design and evaluate certain design elements for reward-based crowdfunding platforms that can engage backers in co-creational activities for product development. The study uses a design science research (DSR) approach and the theoretical concept of psychological ownership to inform a new design and then experimentally test that design. The results suggest that the derived artifacts positively influence co-creational activities in crowdfunding and that feelings of psychological ownership play an important mediating role. The contribution of this research is threefold. First, this paper extends crowdfunding’s application potential from merely a method of financing to a method of value creation with customers for product development. Second, the study advances DSR by applying a new DSR approach that shows whether a design performs as hypothesized by theory. Third, this research allows the exploration of backers’ individual behavior as opposed to their collective behavior.
- ZeitschriftenartikelUnlocking Online Reputation(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Teubner, Timm; Adam, Marc T. P.; Hawlitschek, FlorianWith the ever-growing popularity of sharing economy platforms, complementors increasingly face the challenge to manage their reputation on different platforms. The paper reports the results from an experimental online survey to investigate how and under which conditions online reputation is effective to engender trust across platform boundaries. It shows that (1) cross-platform signaling is in fact a viable strategy to engender trust and that (2) its effectiveness crucially depends on source–target fit. Implications for three stakeholders are discussed. First, platform complementors may benefit from importing reputation, especially when they have just started on a new platform and have not earned on-site reputation yet. The results also show, however, that importing reputation (even if it is excellent) may be detrimental if there occurs a mismatch between source and target and that, hence, fit is of utmost importance. Second, regulatory authorities may consider reputation portability as a means to make platform boundaries more permeable and hence to tackle lock-in effects. Third, platform operators may employ cross-platform signaling as a competitive lever.

- ZeitschriftenartikelStandardization of Forms in Governments(Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Scholta, Hendrik; Balta, Dian; Räckers, Michael; Becker, Jörg; Krcmar, HelmutForms are central interfaces for information exchange between a government and its citizens. As a way to translate laws into practice, forms are an essential part facilitating this exchange. Unfortunately, forms often require substantial development effort to ensure they comply with legal requirements, with the result that citizens often describe them as highly complex. Standardization of forms through reference modeling would help to minimize governments’ effort by reusing elements and would reduce complexity for citizens by providing a unified representation of information. The article contributes a meta-model for a modeling language that can be used in representing reference models for forms. It follows a design science research approach to elicit form structure and editorial process requirements and to iteratively design the meta-model. The paper demonstrates and evaluates the meta-model using focus groups and application in three case studies. It extends research on standardization to reference modeling and government forms.
