    This article focuses on how companies can cope with the enormous volume and variety of data (big data) that is acquired on crowdsourcing platforms from the worldwide community of Internet users. We identify the challenges of implementing crowdsourcing platforms and show how CIOs and other organizational leaders can build the absorptive capacity necessary to extract business value from crowdsourced data.

    Given the rise of the Internet, consumers increasingly engage in co-creating products and services. Whereas most co-creation research deals with various aspects of generating user-generated content, this study addresses designing ratings scales for evaluating such content. In detail, we analyze functional and perceptional aspects of two frequently used rating scales in online innovation communities. Using a multimethod approach, our experiments show that a multicriteria scale leads to higher decision quality of users than a single-criterion scale, that idea elaboration (i.e., idea length) negatively moderates this effect such that the single-criterion rating scale outperforms the multicriteria scale for long ideas, and finally that the multicriteria scale leads to more favorable user attitudes toward the Web site. To ensure robustness of our results, we applied a bootstrap-based Monte Carlo simulation based on our experimental data. We found that around 20 user ratings per idea are sufficient for creating stable idea rankings and that a combination of both rating scales leads to a 63 percent performance improvement over the single-criterion rating scale and 16 percent over the multicriteria rating scale. Our work contributes to co-creation research by offering insights as to how the interaction of the technology being used (i.e., rating scale) and the attributes of the rating object affects two central outcome measures: the effectiveness of the rating in terms of decision quality of its users and the perception of the scale by its users as a predictor of future use.

    Germany is introducing a nation-wide telemedicine infrastructure that enables electronic health services. The project is facing massive resistance from German physicians, which has led to a delay of more than five years. Little is known about the actual burdens and drivers for adoption of e-health innovations by physicians. Based on a quantitative study of German physicians who participated in the national testbed for telemedicine, this article extends existing technology acceptance models (TAM) for electronic health (e-health) in ambulatory care settings and elaborates on determinants of importance to physicians in their decision to use e-health applications. This study explores the opinions, attitudes, and knowledge of physicians in ambulatory care to find drivers for technology acceptance in terms of information technology (IT) utilization, process and security orientation, standardization, communication, documentation and general working patterns. We identified variables within the TAM constructs used in e-health research that have the strongest evidence to determine the intention to use e-health applications. The partial least squares (PLS) regression model from data of 117 physicians showed that the perceived importance of standardization and the perceived importance of the current IT utilization (p<0.01) were the most significant drivers for accepting electronic health services (EHS) in their practice. Significant influence (p<0.05) was shown for the perceived importance of information security and process orientation as well as the documentation intensity and the e-health-related knowledge. This study extends work gleaned from technology acceptance studies in healthcare by investigating factors which influence perceived usefulness and perceived ease of use of e-health services. Based on these empirical findings, we derive implications for the design and introduction of e-health services including suggestions for introducing the topic to physicians in ambulatory care and incentive structures for using e-health.

    Crowdsourcing marketplaces emerged in the internet and enable the integration of customers in various tasks along the innovation process. Marketplaces such as Amazon's Mechanical Turk install a member base for third parties, where they can offer small, highly structured paid tasks which can hardly be solved automatically with information and communication technology (ICT) which we call Pico Jobs. In this paper, a new method for systematically utilising the creative potential of the users of these marketplaces for new product development is illustrated. First, an analysis of related work offers an overview of existing methods for integrating customers into innovation processes and classifies crowdsourcing marketplaces according to existing methods. Second, the characteristics of Pico Jobs are elaborated by reviewing leading crowdsourcing marketplaces. Third, our real-world case with OSRAM pinpoints the features of Pico Jobs for idea generation and validation such as the speed and the dynamic of involving customers into innovation processes. The article concludes with a discussion of potentials and limitations for companies applying Pico Jobs in order to accelerate the integration of customers. Overall, this article contributes a new concept for utilising crowdsourcing and points out opportunities for future research in this area.

    Promoting the Quality of User Generated Ideas in Online Innovation Communities: A Knowledge Collaboration Perspective

    Enabled by Internet-based technologies, users are increasingly participating and collaborating in idea generation in online innovation communities. However, with the limited understanding of the phenomenon, few studies have investigated what determines the quality of ideas. This study aims at addressing the knowledge gap. We find that idea experimentation effort, i.e., the effort associated with creating the idea, and idea review, i.e., comments by other users, influence idea quality. Further, idea recombination, i.e. peer users participating in wiki-based edits, have a positive influence on idea Quality, in case idea experimentation effort was low, and a negative influence in case of high idea experimentation effort. These results contribute to idea generation, knowledge collaboration, and user generated content literature by investigating the mechanisms through which collaboration influences the quality of the collaborative outcome (i.e., idea quality) in online contexts for the first time. Advice for organizations running online innovation communities is provided.

    The Effects of Prediction Market Design and Price Elasticity on Trading Performance of Users : An Experimental Analysis

    We employ a 2x3 factorial experiment to study two central factors in the design of prediction markets (PMs) for idea evaluation: the overall design of the PM, and the elasticity of market prices set by a market maker. The results show that 'multi-market designs' on which each contract is traded on a separate PM lead to significantly higher trading performance than 'single-markets' that handle all contracts one on PM. Price elasticity has no direct effect on trading performance, but a significant interaction effect with market design implies that the performance difference between the market designs is highest in settings of moderate price elasticity. We contribute to the emerging research stream of PM design through an unprecedented experiment which compares current market designs.

    Enabled by Internet-based technologies, users are increasingly participating and collaborating in idea generation in online innovation communities. Beyond increasing the quantity of ideas contributed by users, firms are looking to obtain innovation ideas of better quality. However, with the limited understanding of the phenomenon, few studies have focused on investigating what determines the quality of collaboratively generated user ideas in online innovation communities. This study aims to address this knowledge gap by investigating the antecedents of the quality of user generated ideas from a knowledge collaboration perspective. Based on this perspective, we propose that idea creation effort, peer co- production, and peer feedback will directly and interactively influence the quality of user generated ideas. The model was tested with archival data from the SAPien’s innovation community as well as idea quality rating data from experts. The results reveal that idea creation effort and peer feedback affect the quality of user generated idea. Further, idea creation effort negatively moderates the relationship between peer co- production and the quality of user generated ideas.
