- PublicationMétadonnées seulementThe Contribution of Reference Modeling for Organizing Enterprise Mashup EnvironmentsA new kind of Web-based applications, known as Enterprise Mashups, has gained momentum in the recent years. The vision is that business users with no or limited programming skills are empowered to leverage in a collaborative manner user friendly building blocks in the envisioned Enterprise 2.0. However, the transfer of this concept into practice is still a serious issue. Whereas most research focuses on technical aspects, we point the organizational dimension of implementing Enterprise Mashups. In particular, we claim that new capabilities are needed within the implementing organization that have yet to be discovered. For that purpose we propose a reference model for organizing Enterprise Mashup environments. We also report on two applications of this model within the projects SAP Research RoofTop Marketplace and FAST. In summary, we reflect on the usefulness of the reference model for making Mashups happen in enterprise environments.
- PublicationMétadonnées seulementHow to handle the Long Tail of Business Negotiations: The Open Negotiation Environment (ONE) PlatformIn course of the EU-funded project Open Negotiation Environment (ONE), an Open Source platform was developed which allows modelling and executing of individual complex business negotiations. This paper focuses in particular on unstructured business negotiations. Instead of following a pre-defined negotiation process, real-world business negotiations are characterised by serveral negotiations steps within the different negotiation phases (admission, readiness, negotiation, and acceptance). By following the design science research methodology, this paper presents a report of the achieved results in each phase of the design science approach. The designed and underlying meta model to model business negotiations are introduced. By means of a developed prototype the application is demonstrated. A case study in the facility management in Italy evaluates the underlying concepts and benefits of the solution.
- PublicationMétadonnées seulementLightweight Composition of Ad-Hoc Enterprise-Class Applications with Context-aware Enterprise MashupsThe huge demand for ad-hoc and situational enterprise-class applications led to a new kind of Web-based applications, known as enterprise mashups. End users from the business units with no programming skills are empowered to combine and reuse existing company internal and external resources within minutes to new value added applications. In order to handle the growing number of mashable components, we propose a context-aware concept for enterprise mashups that supports users to find relevant components according to their current situation and to compose them automatically. The designed context model which is structured in the three domains agent, computing and environment is implemented in the SAP Research RoofTop Marketplace prototype to demonstrate its applicability and business benefits.
- PublicationMétadonnées seulementDesign Principles of Enterprise MashupsA new kind of Web-based application, known as Enterprise Mashups, has been gaining momentum in the last years. Enterprise Mashups implicate a shift concerning a collaborative software development and consumption process. End users combine and reuse existing Web-based resources within minutes to new value added applications in order to solve an individual and ad-hoc business problem. Novel design principles are currently about to emerge allowing to cover the long tail of user needs. In this position paper, we introduce the terminology used in context of this new paradigm and present an Enterprise Mashup Stack which consists of three layers: Web-based resources, widgets, and Mashups. Based on this model, we elaborate on the design principles of upcoming intermediaries and the mass collaboration form, the lightweight composition style as well as the perpetual beta development model. By means of the EU funded research project FAST, we show their real-world applicability. http://www.km-conference2009.org/workshops/KSM09.php

- PublicationMétadonnées seulementGeneric Business Model Types for Enterprise Mashup IntermediariesThe huge demand for situational and ad-hoc applications desired by the mass of business end users led to a new kind of Web applications, well-known as Enterprise Mashups. Users with no or limited programming skills are empowered to leverage in a collaborative manner existing Mashup components by combining and reusing company internal and external resources within minutes to new value added applications. Thereby, Enterprise Mashup environments interact as intermediaries to match the supply of providers and demand of consumers. By following the design science approach, we propose an interaction phase model artefact based on market transaction phases to structure required intermediary features. By means of five case studies, we demonstrate the application of the designed model and identify three generic business model types for Enterprise Mashups intermediaries (directory, broker, and marketplace). So far, intermediaries following a real marketplace business model don?t exist in context of Enterprise Mashups and require further research for this emerging paradigm.
