    What are the Business Benefits of Enterprise Mashups?

    Enterprise mashups (EMs) are a new technology that enables the automation of situational needs of knowledge workers. EMs imply a new development paradigm based on the peer production philosophy and empower end users to create individual applications without the involvement of the IT department. So far, there is insufficient research on potential benefits of EMs. This paper contributes to fill this gap by designing an EM benefit model. By following the design science approach, the balance scorecard concept is leveraged to identify and structure potential benefits of EMs. By means of a laboratory experiment and a case study, the applicability of the designed benefit model is demonstrated.

    The 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.

    SAP Research RoofTop Marketplace: Putting a Face on Service-Oriented Architectures

    The huge demand for situational and ad-hoc applications desired by the mass of business end users cannot be fully covered by traditional Service-Oriented Architectures (SOAs). By putting a face on SOA, Enterprise Mashups empower these end users to combine and reuse Web-based resources within minutes to create value added applications. In this paper, we present the SAP Research RoofTop Marketplace prototype that transfers established marketplace concepts to the Enterprise Mashup paradigm in order to leverage the power of peer production. The underlying concepts and the resulting architecture of the platform are presented. By means of a business scenario, the features of the grassroosts Enterprise Mashup platform are demonstrated.

    Business Models for Digital Business Ecosystems: The Case of the Open Negotiation Environment (ONE) Platform
    (IEEE Computer Society, 2009-06-01)

    The process of business negotiations of complex products or services is an essential binding element in today's dynamic global markets. The Digital Business Ecosystem (DBE) paradigm provides a concept for understanding such dynamic global businesses. However, an analysis form a business model perspective is still missing. This paper presents the case study of an envisioned Open Source decentralized negotiation platform which is currently under development. In contrast to existing negotiation platforms such as Ebay in the B2C market or Ariba in the B2B market, the negotiation platform is based on a decentralized philosophy both on technical and organiza-tional level following the DBE paradigm. The analysis is structure along seven major components according to the MCM Business Model Framework: features of the specific product or service, features for the specific medium (technology), potential customers, value chain, financial flow, flow of goods and services, societal environment. As a result, we categorize the characteristics and challenges in the different business model components providing the foundation to analyze further business ecosystems from a business model perspective.

    How to handle the Long Tail of Business Negotiations : The Open Negotiation Environment (ONE) Platform

    Stanoevska-Slabeva, Katarina
    In 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.

    A 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.

    A new paradigm, known as Enterprise Mashups, implicates a shift concerning the service development and consumption process: end users combine and reuse existing Web-based resources within minutes to new applications in order to solve an individual and ad-hoc business problem. In such democratized operational environments, the role of IT departments is changing. They are no longer solely responsible for developing or installing business applications. Instead, end users in the business units compose their own operational environment in a collaborative manner. This paper analyses and discusses challenges and the changing role of IT departments toward service intermediaries.

    Practical Guidelines for Evolving IT Infrastructure towards Grids and Clouds

    In the previous chapters of this book the foundation of Grid and Cloud Computing were described and their application in companies was illustrated with examples. Grid Computing enables sharing of and access to distributed and heterogeneous computing resources as well as establishment of VOs. Through virtualization, heterogeneous pools of servers, storage systems and networks are pooled together into a virtualized system that is exposed to the user as a single computing entity. This entity can be centrally monitored and assigned to computing tasks. Overall, Grid Computing enables a virtualization layer that is placed between the heterogeneous infrastructure and the specific user application using it. Grid Computing potentially results in higher flexibility of computing resources and their more efficient utilization, and by that, enables an environmentally friendlier IT management in companies. Cloud Computing evolved from and builds upon the convergence of Grid Computing and SOC. It has the potential to substantially change the way how computing resources are consumed. Core features of Cloud Computing are integrated support for IaaS, PaaS and SaaS as well as user-friendly and service-oriented interfaces for developers and users. Cloud Computing offers a new, easy-to-use way for increasing scalability and flexibility of own IT resources on demand. Sudden peaks can be accommodated with access to external resources provided in a payper- use manner without additional investments in hardware, data centres and related human resources required for maintenance and support. Cloud Computing provides also new opportunities for Independent Software Vendors. They can develop innovative business models and offer their software in a SaaS manner without building up the necessary infrastructure.

    Mashups ermöglichen es Endnutzern, individuelle Applikationen innerhalb von Minuten zu erstellen. Die IT-Abteilung spielt dabei eine neue Rolle als Vermittler zwischen Anwendern sowie internen und externen Diensteanbietern. Mit klassischem Projektmanagement kommt man hier nicht weiter. Agile Method eignen sie jedoch gut für die Aufgabe.
