Abstract

When developing peer-to-peer applications on Distributed Ledger Technology (DLT), a crucial decision is the selection of a suitable DLT design (e.g., Ethereum) because it is hard to change the underlying DLT design post hoc. To facilitate the selection of suitable DLT designs, we review DLT characteristics and identify trade-offs between them. Furthermore, we assess how DLT designs account for these trade-offs and we develop archetypes for DLT designs that cater to specific quality requirements. The main purpose of our article is to introduce scientific and practical audiences to the intricacies of DLT designs and to support development of viable applications on DLT.

Abstract

While the importance of information system (IS) certifications to demonstrate compliance with security and personal data protection requirements is constantly increasing, competing (theoretical) viewpoints exist that outline the rationales for organizations to adopt certifications. The results of these competing perspectives are inconclusive research findings in the certification adoption literature. While organizations may use certifications to signal quality to consumers, others mainly adopt certifications to improve internal processes or create institutional legitimacy. To enhance our understanding of the motivation for online vendors to adopt IS certifications, we conduct a literature review and a ranking‐type Delphi study with two unique panels comprising certified online vendors (N = 15) and certification authorities (N = 24). As a result, we provide a rank‐order list of 24 motivators and 17 demotivators impacting online vendors’ intentions to adopt IS certifications. We reveal that certain motives are context‐independent, whereas other motives are specific for electronic markets (e.g., “signal data protection”). We also provide rich descriptions of potential demotivators, thereby increasing our understanding of the boundary conditions for IS certification adoption. Comparing our findings to three competing theoretical perspectives enabled us to derive a typology of distinctive certification adopters: functionalists, institutionalists, and signalers. In developing this typology, our findings constitute a first step toward alleviating the inconclusive findings in the academic literature as well as highlighting differences in motivating and inhibiting factors that impact vendors’ adoption intentions.

Abstract

Whereas the importance of information system (IS) certifications is increasing to prove compliance with regulatory and industry requirements, research reveals inconsistent findings concerning the effectiveness of IS certifications. Prior studies have concluded that such inconsistent findings stem partly from users' limited understanding of the nature and role of certifications due to ineffective certification presentations. We follow a three-phase, theory-driven design science approach to examine how to design effective certification presentations. First, we identified sources of users' limited understanding and formulated a revised certification presentation that facilitates users' peripheral information processing. We tested our design proposal in an online experiment with 300 participants. Second, we derived meta-requirements and design guidelines by validating a theory-driven model of certification presentations through an online survey with 352 participants. Third, we implemented three certification presentations complying with example guidelines and ran an online experiment with 400 participants to test whether these presentations are effective. We contribute to research and practice by proposing a design theory for certification presentations composed of peripheral cues inducing authority, social proof and likeability to increase users' trust perceptions.
