Design Principles of Enterprise Mashups

2009-03-25 , Hoyer, Volker , Stanoevska-Slabeva, Katarina , Hinkelmann, Knut , Wache, Holger

A 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

Enterprise Mashups: Design Principles towards the Long Tail of User Needs

2008-07-08 , Hoyer, Volker , Stanoevska-Slabeva, Katarina , Janner, Till , Schroth, Christoph

A new type of Web-based applications, known as Enterprise Mashups, has been gaining momentum in the last years. Novel design principles are currently about to emerge allowing to cover the long tail of user needs and to provide individual and heterogeneous enterprise applications in a shorter time. In this paper, we introduce the main components of this new paradigm, and discuss the design principles of the architecture (Enterprise Mashup Stack), upcoming intermediaries and mass collaboration, lightweight composition as well as perpetual beta development model. Conference: http://conferences.computer.org/scc/2008/ Services now account for more than half of the U.S. economy. Services Computing, as a new cross discipline, addresses how to enable IT technology to help people perform business services more efficiently and effectively. Building on its great success in 2004, 2005, 2006, 2007, the 2008 IEEE International Conference on Services Computing (SCC 2008) continues to bridge the gap between Services Computing and Business models with an emerging suite of ground-breaking technology that includes service-oriented architecture (SOA), business process integration and management, services engineering and grid/utility computing, and Web 2.0. The theme of SCC 2008 is "Services: Business, Technology, and Application". From the technology foundation perspective, Services Computing has become the default discipline in the modern services industry. SCC 2008 will be co-located with and strategically part of the 2008 IEEE Congress on Services (SERVICES 2008) to explore "Services" (Science and Technology), which has been formally promoted by IEEE Computer Society since 2003! IEEE Services Oriented Architecture (SOA) Industry Summit, IEEE International Services Computing Contest, IEEE SOA Standards Symposium, IEEE Services Computing Workshops, IEEE Services Computing Ph.D. Student Symposium will be featured at this joint event in Hawaii, USA. Services Computing, as a new cross discipline, addresses how to enable IT and computing technology to help people perform business processes, services, and applications more efficiently and effectively. At the core of a business model is a set of processes that jointly help yield a profit in an organization. As we can see, Services Computing currently shapes the thinking of business modeling, business consulting, solution creation, service delivery, and software architecture design, development and deployment. The global nature of Services Computing leads to many opportunities and few challenges and creates a new networked economic structure for supporting different business models. SCC 2008 has the following major research tracks: Foundations of Services Computing, Services-Centric Business Models, Business Process Management and Integration, and SOA Tools, Solutions and Services. SCC 2008 is sponsored by the IEEE Computer Society Technical Committee on Services Computing. SCC 2004 was held in Shanghai, China, September 15-18, 2004 . SCC 2005 was co-located with ICWS 2005 on July 11-15, 2005 in Orlando, Florida, USA. SCC 2006 was co-located with ICWS 2006 on September 18-22, 2006 in Chicago, Illinois, USA. SCC 2007 was co-located with ICWS 2007 on July 9-13, 2007 in Salt Lake City, Utah, USA. The SCC Proceedings have been included in EI Compendex. SCC 2008 will concentrate on the science and technology of Business/Application Services and the bridging technologies such as Business Strategy and Design, Business Process Integration and Management, Grid and Utility Computing, and SOA Services and Solutions; while ICWS 2008 will continue to put its focus on all aspects of Web services from Computer Science and Engineering perspectives.

Generic Business Model Types for Enterprise Mashup Intermediaries

2009-08-06 , Hoyer, Volker , Stanoevska-Slabeva, Katarina , Nelson, Matthew L.

The 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.

Towards a Reference Model for Grassroots Enterprise Mashup Environments

2009-06-08 , Hoyer, Volker , Stanoevska-Slabeva, Katarina , Newell, Susan

A new kind of Web-based application, known as Enterprise Mashups, has gained momentum in the last years: Business users with no or limited programming skills are empowered to leverage in a collaborative manner user friendly building blocks and to 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. Current discussions of the Mashup paradigm in the scientific community are limited on technical aspects. The collaboration and the peer production management aspects of the Mashup development have received less attention yet. In this paper, we propose a reference model for Enterprise Mashups which provides a foundation to develop and to analyse grassroots Enterprise Mashup environments from a managerial and collaborative perspective. By following the design science research approach, we investigate existing reference models and leverage the St. Gallen Media Reference Model (MRM). The development of Enterprise Mashups is structured by market transaction phases similar to electronic markets. The user roles, the necessary processes and the resulting services are modelled according to the views of the MRM. By means of the SAP Research RoofTop Marketplace prototype we demonstrate the application of the designed reference model for grassroots Enterprise Mashups environments.
