How collaborative technology supports cognitive processes in collaborative process modeling: A capabilities-gains-outcome model

We examine which capabilities technologies provide to support collaborative process modeling. We develop a model that explains how technology capabilities impact cognitive group processes, and how they lead to improved modeling outcomes and positive technology beliefs. We test this model through a free simulation experiment of collaborative process modelers structured around a set of modeling tasks. With our study, we provide an understanding of the process of collaborative process modeling, and detail implications for research and guidelines for the practical design of collaborative process modeling.

An Exploratory Study of IT-Enabled Collaborative Process Modeling

Process modeling is an important design practice in intra- as well as inter-organizational process improvement projects. Inter-organizational process modeling often requires collaboration support for distributed participants. We present the results of a preliminary exploratory of study of process modeling on basis of collaborative technology. We examine a group of process modelers that rely on a collaborative modeling editor to complete two process modeling tasks in distributed settings. We examine how the participants learn to appropriate the technology, the key phases and tasks of collaborative process modeling, the breakdowns encountered and workarounds employed by the participants. With our study, we provide a first understanding of the IT-enabled process of process modeling, and detail a set of guidelines and implications for the research and design of collaborative process modeling.

Digitalisierung der IT-Industrie mit Cloud Plattformen – Implikationen für Entwickler und Anwender

ZusammenfassungDie zunehmende Bedeutung und Verbreitung von Plattform Ökosystemen beeinflusst insbesondere auch die IT-Industrie. Eine daraus resultierende Modularisierung ermöglicht eine stärkere Serviceorientierung von Infrastruktur- und Anwendungsarchitekturen insbesondere vor dem Hintergrund des Cloud Computing. Dabei ermöglicht das Plattform-Konzept den beteiligten Partnern die Erzeugung von jeweils größerem Mehrwert, als jeder Einzelne im Stande wäre (Value Co-Creation) hinsichtlich Effizienz oder verteilter Innovationen. Dahingehend soll im Rahmen dieses Artikels ein vertieftes Verständnis für Plattformen im Enterprise Software Segment erzeugt werden. Zunächst wird der Begriff der Cloud Plattform Ökosysteme konzeptualisiert werden und deren Funktionalitäten beschrieben. Darüber hinaus werden generische Wertschöpfungs- und Wertabschöpfungsmechanismen benutzt, um das Geschäftsmodell der Cloud Plattformen aus Sicht der Plattformbetreiber zu charakterisieren. Anschließend werden die verschiedenen Wertschöpfungsmechanismen für weitere beteiligte Akteure (B2B Endkunden, Entwickler/ISVs, Integratoren etc.) näher beleuchtet. Dabei stehen potentielle Handlungsfelder und Risiken im Fokus der Betrachtung, die anhand der generischen Mechanismen für die jeweiligen Akteure detailliert analysiert werden. AbstractThe growing proliferation and dispersion of cloud platform ecosystems particularly impacts the IT industry. The resulting modularity enables an increased service orientation of infrastructure and application architectures, especially with respect to Cloud Computing. The combined offerings of Cloud platform ecosystems can exceed capacities and capabilities of what can be provided by any single company (value co-creation) considering efficiency or open innovation. Thus within the scope of this article we want to provide a detailed analysis of platforms within the enterprise software segment. At first, we will conceptualize the term cloud platform ecosystem and describe the associated functionalities. We will then utilize generic mechanisms for value creation and appropriation to analyze the business model of platform providers. Subsequently, we will describe the detailed value creation and appropriation mechanisms for the other actors within this segment (B2B users, developers/ ISVs, system integrators). In particular, we will focus on potential opportunities and associated risks derived by the generic mechanisms for each ecosystem role.

Geschäftsmodelle im Cloud Computing

Laut aktuellen Umfragen ist Cloud Computing eines der meist diskutierten Themen in der Informationstechnologie (IT). Gartner, eines der weltweit fuhrenden Forschungs- und Beratungsunternehmen in der IT, wahlte Cloud Computing in den Jahren 2009, 2010 und 2011 an die Spitze und auch fur das Jahr 2012 wieder in die Top 10 der strategischen Technologien. Die Analysten von techconsult ermitteln in ihrem IT-Cloud-Index einen kontinuierlichen Anstieg der Verbreitung des Cloud-Einsatzes.

LEVERAGE ONCE, EARN REPEATEDLY – CAPABILITIES FOR CREATING AND APPROPRIATING VALUE IN CLOUD PLATFORM ECOSYSTEMS

Information technology (IT) advancements enabled new delivery models (i.e. Cloud Computing), thereby facilitating the emergence of new business models in the IT industry, such as Cloud platform ecosystems. With their growing acceptance and diffusion in practice, we need a deeper understanding of their IT capabilities in order to implement their business model, thereby creating and appropriating value. We draw on empirical data from four case studies of Cloud platform ecosystems utilizing a framework on IT-enabled business models for data analysis. We found four key motivations for interfirm collaboration that each generated business model requirements specified in the context of Cloud platform ecosystems. These drive the development of unique B2B IT capabilities enabling value creation and appropriation mechanisms. We propose three dyadic (relation-specific) IT customization and two network IT standardization (network-oriented) capabilities based on our cross case analysis. Furthermore, we describe prevalent value creation and appropriation mechanisms and suggest two additional mechanisms grounded in the data: downstream capabilities and platform resourcing. We provide a possible reasoning on the underlying logic of IT capabilities, value creation and appropriation of Cloud platform ecosystems.
