PublicationHow to Empower the Workforce – Analyzing Internal Crowd Work as a Neo-Socio-Technical System( 2019-01-08)
;Durward, David ;Simmert, BenediktIn this paper, we analyze internal crowd work as Neo-STS from an employee’s perspective. Based on qualitative interviews, we describe in our model how employees perceive empowerment through participation in internal crowd work. As our main contribution, we detail and extend existing research regarding internal crowd work, Neo-STS as well as empowerment by identifying structural antecedents that affect psychological empowerment of internal crowd workers.Type: conference paperJournal: Hawaii International Conference on System Sciences (HICSS) -
PublicationThe Rise of Crowd Aggregators - How Individual Workers Restructure Their Own Crowd( 2017-02-12)
;Durward, DavidCrowd work has emerged as a new form of digital gainful employment whose nature is still a black box. In this paper, we focus on the crowd workers – a perspective that has been largely neglected by research. We report results from crowd worker interviews on two different platforms. Our findings illustrate that crowd aggregators as new players restructure the nature of crowd work sustainably with different effects on the behavior as well as the existing relationships of crowd workers. We contribute to prior research by developing a theoretical framework based on value chain and work aggregation theories which are applicable in this new form of digital labor. For practice, our results provide initial insights that need to be taken into account as part of the ongoing discussion on fair and decent conditions in crowd work.Type: conference paper -
PublicationBlueprinting Crowdfunding - Designing a Crowdfunding Service Configuration Framework( 2017-02-12)Crowdfunding gained momentum over the last few years. In contrast to traditional forms of funding, the service provision of crowdfunding platforms is performed within service systems. These comprise a complex combination of IT and non-IT services, different stakeholders, and diverging contexts and purposes. The design and operation of such service systems represents a tough challenge. Therefore, we developed a crowdfunding service configuration framework in the form of a morphological box and derived three dominant design patterns by following a design science approach. Therefore, we followed three iterations, which comprise in total twelve expert interviews, three case studies and the analysis of 161 crowdfunding platforms. The configuration framework extends research on crowdfunding and service science by providing insights in how to support the systematic design of crowdfunding service systems, reducing their complexity, and giving a comprehensive overview over their building blocks.Type: conference paper

PublicationThird Time is a Charm-Determining the Required Number of Assessors when Using Peer Assessment in Large-Scale Lectures( 2017-12-10)
;Lehmann, KatjaAlthough peer assessment is a widely used didactical method in higher education, little is known about a) how many peer assessors are required to receive a stable assessment on a peer's solution and b) how valid this assessment is compared to an expert assessment. To fill these gaps, we conducted a peer assessment in a large-scale lecture. Overall, 136 students participated in the peer assessment. Each student had to complete an assignment, which was then anonymously evaluated by five randomly selected peers, and three independent experts. We applied a bootstrap-based Monte Carlo simulation based on our data. The results show that a) three peer assessors are sufficient for a stable assessment, and b) the peer assessors are less critical compared to experts. We thus contribute to literature by providing insights on how many peer assessors are required when applying peer assessment, and how comparable peer assessment is with expert assessment.Type: conference paperJournal: International Conference on Information Systems (ICIS) -

PublicationManaging Disruptive Innovation through Service Systems – The Case of Crowdlending in the Banking Industry(Association for Information Systems, 2016-12-11)
;Jakob, ThomasThe Internet has affected and partially radically changed the business models of traditional industries. Crowdfunding as a new concept of funding over the Internet by a large crowd has especially gained maturity. Crowdfunding offerings range from funding charitable projects or innovative gadgets to a funding alternative for start-ups or small businesses. Therefore, crowdfunding represents an innovative way to provide liquidity for illiquid markets. With regard to the banking crisis and the growing skepticism toward banks, crowdfunding is seen as a more transparent, democratic, and entertaining way of funding, which makes it highly attractive for banks. A senior innovation manager of The Bank of Switzerland (TBOS), one of Switzerland’s largest and most traditional banks, recognized the disruptive and beneficial potential of crowdlending. By facing strong resentments, he developed the idea of TBOS engaging in crowdlending by collaborating with a start-up by bundling competencies in a service system.Type: conference paper -
PublicationIs There PAPA in Crowd Work? : A Literature Review on Ethical Dimensions in CrowdsourcingThe phenomenon of crowdsourcing has emerged as a new pattern of digitally mediated collaboration. This novel socio-technical arrangement changes the organization of work as well as its general nature and takes place in information systems (IS) in which humans face many threats to their dignity. For this reason, the importance of ethical issues within this new form of employment arises. Hence, in this paper we focus on the ethical issues in crowd work – a perspective that has been largely neglected by current crowdsourcing research. We analyze recent crowdsourcing literature and extract ethical issues by following the PAPA (privacy, accuracy, property and accessibility of information) concept, a well-established approach in IS. The review focuses on the individual perspective of crowdworkers, which addresses their working conditions and benefits. Although, the literature review exhibits that there are PAPA dimensions in crowdsourcing, only few focus on the crowdworkers as individuals. Our findings contribute to further research in crowdsourcing by introducing an ethical framework and give practical insight into how to design sustainable and ethical crowd work.Type: conference paper

PublicationRags to Riches - How signaling behaviour causes a power shift in crowdsourcing marketsCrowdsourcing has emerged as new form of digital work organization. This novel socio-technical ar-rangement changes the organization of work as well as its general nature. In this paper, we focus on the crowdworkers – a perspective that has been largely neglected by crowdsourcing research. We re-port results from crowdworker-interviews on two different platforms. Our research shows that quality signals of crowdworkers increase the bargaining power towards their principals, i.e. the crowdsourcers. As a result, the crowdworkers can reach a turning point of critical bargaining power at which the distribution of power shifts in their favor. We contribute to the literature by unraveling signaling behavior as mechanism influencing bargaining power and thus success in crowdsourcing. Beyond, we develop a theoretical model that indicates a shift in bargaining power over time and im-proves our understanding of crowdsourcing as novel way of organizing digital work. For practice, our results provide guidelines for crowdworkers how to improve their position in bargaining in relation to the crowdsourcer.Type: conference paper
