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.
The Ph.D. is about you." At a Ph.D. colloquium, a senior scholar of my research discipline taught us once the lesson that the outcome of a Ph.D. should be far more than the final thesis or another fancy academic title. Rather, doing a Ph.D. should be about selfimprovement and about being better than you were the day before. Having completed my Ph.D. at the University of Mannheim, I am fortunate to say that I have spent most of my personal resources during the last 4 years on developing myself, my way of thinking, my way of working, and my way of interacting with people. Achievements and failures were equally important experiences on the way to completing it. The content of this book presents my reflections and best research practices of 4 years of studying socio-technical phenomena surrounding cloud computing. There are many people who I like to thank for encouraging, supporting, and inspiring me over the last 4 years in this process. I am especially grateful with my supervisor, Prof. Dr. Daniel Veit with whom I enjoyed a very productive and collaborative relationship over the last few years. It was Daniel who gained me access to so many valuable resources. Between 2010 and 2014, I was honored to discuss my cloud research at various national (
In spite of high potentials and sophisticated goals set by federal governments, municipalities are reluctant to move procurement to the Internet. This study focuses on determinants of E-Procurement adoption at the municipal level. Considering previous research as well as public and private sector differences, a research model is developed, which is further examined by collecting and analyzing data from a multiple-case study of 13 German municipalities. Based on the empirical results, practical implications and areas of future work are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
