The relevance of customer win-back for digital firms: A novel framework and analytical perspective on reacquired customers

Subscriptions represent the monetization strategy of choice for many digital services. Research on mature industries highlights the profitability of subscription win-back efforts, yet no study specifies the impact of reacquired customers relative to first-lifetime customers in the interplay of acquisition and retention strategies adopted by digital firms. Such considerations are critical for assessing current win-back strategies and forecasting acquisition and retention success though. A proposed win-back assessment framework, in accordance with a novel analytical perspective, offers insights along these lines, by comparing the value of reacquired customers against that of customers in their first lifetime, from the same cohort, to determine the relevance of win-back activities. When applied to a digital subscription service, the results of a field experiment reveal an apparent contradiction, such that reacquired customers live on average 171% longer than in their previous lifetime, but 33% shorter than first-lifetime customers from the same cohort. The authors explain the factors underlying this observation and its implications.

Manage scaling in artificial intelligence ventures

Digital innovations enable new ventures to rapidly scale their business. Information systems research has largely explained scaling on the basis of network effects on user bases in platform markets. It cannot sufficiently explain scaling in digital ventures that integrate artificial intelligence (AI) algorithms into the core of their offerings. While these ventures attract similar funding and grow at analogous paces as (digital) platforms, we find many examples not relying on network effects of growing user bases within singular contexts. Instead, AI ventures in early stages apply their offerings to diverse contexts, relying on expanding training data more than on users. AI algorithms, however, are trained in specific contexts and can hardly act on events they have not been designed for. This so-called ‘framing problem’ leads to a conundrum as it might inhibit swift innovation from data-driven operations in new ventures that pursue rapid scaling. We introduce an exploratory, qualitative study of fifteen cases across Europe to reveal how AI ventures change the mechanism of scaling from user base to lateral scaling. By introducing the mechanisms of AI thresholding and AI locking, we do not only explain how ventures manage the ‘framing problem’, but also contribute to research on scaling as we outline how direct and indirect network effects substitute each other for AI ventures.

Eyes Wide Open: The Role of Situational Information Security Awareness for Cognitive Appraisals and Security-Related Behavior

Phishing emails continue to make their way to users’ inboxes at organizations, putting users under the constant threat of data or identity theft. In finding ways to motivate users to protect themselves and their organization from such threats, information security researchers have made notable contributions on how individuals’ threat and coping appraisal processes shape adaptive responses. What is largely lacking, however, is an understanding of what influences these appraisal processes in a security-related situation, particularly which information cues are salient for users in terms of developing awareness of the situation in order to identify an email as threat. To observe this link, we derive and define situational information security awareness based on situation awareness literature and examine its impact on threat and coping appraisals in a multi-method phishing experiment including eye tracking and survey components with 107 employees. The results underscore the importance of situational information security awareness and show that past experience with phishing and a security warning positively impact awareness, which in turn increases perceived threat and perceived coping efficacy and, ultimately, actual behavioral responses to phishing attacks

Daring to Do Good Design Science Research

Doing good design science research (DSR) is an audacious venture. It is not a journey for those who value conclusive and repeatable research results. DSR projects aspire to create innovative digital artifacts that solve real-world problems in bounded application domains by providing improvements to conditions of the impacted individuals, groups, and societies. Research results include both the designed artifacts and evidence of their impacts along with a fuller scientific understanding via design theories of why the artifacts provide enhancements (or, disruptions) to the relevant application contexts. However, even the most useful results are often eclipsed by rapid changes in the problem and solution spaces. This presentation will survey key challenges of doing good DSR. The challenges of complexity, creativity, control, contribution, and sustainability will be described, examined, and illustrated with recent research results. While formidable challenges exist, doing good DSR is fun and satisfying. You change the world!
