Weaving risk identification into crowdsourcing lifecycle

© 2015 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license. Crowdsourcing enables companies and individuals as well to tap into the versatile knowledge, creativity, and talent of a large population of crowd contributors. Yet, crowdsourcing can expose companies to a myriad of risks that can have drastic impact on the profitability and competitive position. This paper presents a Risk Breakdown Structure (RBS) of crowdsourcing projects that spans the entire project\u27s lifecycle. The paper first reports on a lifecycle model that captures the main phases of a crowdsourcing project. It then identifies the risk factors associated with each phase of the crowdsourcing lifecycle and discusses the impact of these identified risk factors on the crowdsourcing company. The proposed RBS calls for the need to pay close attention to risk monitoring during each phase of the crowdsourcing lifecycle

Social Media in the Context of Development: A Case Study of Dutch NGOs

This paper presents views of six Dutch development NGOs on possibilities and threats of social media for their work. A systematic analysis of the literature and the systematic analysis of the interviews yield an interesting theoretical framework in which social media characteristics are cross-referenced with NGO organisational characteristics. The resulting preliminary framework of emerging themes suggests that potential disadvantages associated with social media use may impede the organisational use. Fur-thermore it is suggested that potential organisational uses of social media may motivate use and adaptation of the social media use to a development context. It is also suggested that disadvantages attributed to social media may influence the use or non-use of social media for particular developmental activities

Human Computation and Convergence

Humans are the most effective integrators and producers of information, directly and through the use of information-processing inventions. As these inventions become increasingly sophisticated, the substantive role of humans in processing information will tend toward capabilities that derive from our most complex cognitive processes, e.g., abstraction, creativity, and applied world knowledge. Through the advancement of human computation - methods that leverage the respective strengths of humans and machines in distributed information-processing systems - formerly discrete processes will combine synergistically into increasingly integrated and complex information processing systems. These new, collective systems will exhibit an unprecedented degree of predictive accuracy in modeling physical and techno-social processes, and may ultimately coalesce into a single unified predictive organism, with the capacity to address societies most wicked problems and achieve planetary homeostasis.Comment: Pre-publication draft of chapter. 24 pages, 3 figures; added references to page 1 and 3, and corrected typ

Making an Impression Through Openness: How Open Strategy-Making Practices Change in the Evolution of New Ventures

While previous open strategy studies have acknowledged open strategy's function as an impression management instrument, their focus has mostly been on short episodes. The impression management literature, meanwhile, pays openness scant attention. By studying how new ventures engage in open strategy-making, we track how open strategy-making and respective impression management benefits evolve over time. Specifically, we draw on a comparative case study of two firms' blog communication on strategy-related issues and corresponding audience responses over a four-year period. We identify three distinct modes of how organizations engage in open strategymaking with external audiences and show how each mode is related to a specific set of impression management effects. Having established the impression management functions of these modes, we then demonstrate how open strategy-making contributes to new ventures' quests for legitimacy as they evolve. In the launch phase, dialoguing with blog audiences helps a venture attract endorsements for its organization and products. As the venture grows, concentrating on broadcasting relevant strategic information may attract media audiences' additional support for pursuing openness as a desirable organizational practice

When situativity meets objectivity in peer-production of knowledge:the case of the WikiRate platform

PurposeThe purpose of this paper is to further the debate on Knowledge Artefacts (KAs), by presenting the design of WikiRate, a Collective Awareness platform whose goal is to support a wider public contributing to the generation of knowledge on environmental, social and governance (ESG) performance of companies.Design/methodology/approachThe material presented in the paper comes from the first-hand experience of the authors as part of the WikiRate design team. This material is reflexively discussed using concepts from the field of science and technology studies.FindingsUsing the concept of the “funnel of interest”, the authors discuss how the design of a KA like WikiRate relies on the designers’ capacity to translate general statements into particular design solutions. The authors also show how this funnelling helps understanding the interplay between situativity and objectivity in a KA. The authors show how WikiRate is a peer-production platform based on situativity, which requires a robust level of objectivity for producing reliable knowledge about the ESG performance of companies.Originality/valueThis paper furthers the debate on KAs. It presents a relevant design example and offers in the discussion a set of design and community building recommendations to practitioners

OSCAR: A Collaborative Bandwidth Aggregation System

The exponential increase in mobile data demand, coupled with growing user expectation to be connected in all places at all times, have introduced novel challenges for researchers to address. Fortunately, the wide spread deployment of various network technologies and the increased adoption of multi-interface enabled devices have enabled researchers to develop solutions for those challenges. Such solutions aim to exploit available interfaces on such devices in both solitary and collaborative forms. These solutions, however, have faced a steep deployment barrier. In this paper, we present OSCAR, a multi-objective, incentive-based, collaborative, and deployable bandwidth aggregation system. We present the OSCAR architecture that does not introduce any intermediate hardware nor require changes to current applications or legacy servers. The OSCAR architecture is designed to automatically estimate the system's context, dynamically schedule various connections and/or packets to different interfaces, be backwards compatible with the current Internet architecture, and provide the user with incentives for collaboration. We also formulate the OSCAR scheduler as a multi-objective, multi-modal scheduler that maximizes system throughput while minimizing energy consumption or financial cost. We evaluate OSCAR via implementation on Linux, as well as via simulation, and compare our results to the current optimal achievable throughput, cost, and energy consumption. Our evaluation shows that, in the throughput maximization mode, we provide up to 150% enhancement in throughput compared to current operating systems, without any changes to legacy servers. Moreover, this performance gain further increases with the availability of connection resume-supporting, or OSCAR-enabled servers, reaching the maximum achievable upper-bound throughput
