This study examines learning effects (i.e., the effects of prior experience) in information systems development (ISD). ISD is characterized by disparate tasks, teams, and levels of project complexity across projects. These features challenge our understanding of how learning effects occur in the ISD context. Drawing on the theory of transfer of learning, this study examines how ISD project teams learn and under what conditions the learning effects are stronger or weaker. We find that ISD project

What type of knowledge, among domain, technology, and methodology knowledge, is most influential to the performance of software development? We answer to this question by empirically investigating the learning and forgetting curves in software development using an extensive archival data set of software development projects in an IT service company. We find that prior experiences with the same methodology or technology have a stronger impact on software project performance than those in the same

We study a new dynamic order acceptance and assignment problem of a make-to-order manufacturing or service system that produces heterogeneous products or services using heterogeneous servers. Unlike traditional dynamic order acceptance and assignment problems, in our settings the system can strategically postpone acceptance and assignment decisions for orders in hand. The system does this while waiting for more profitable orders to come and/or more productive servers to become available, with th

ABSTRACT This study investigates the effects of media affordances and information security awareness on knowledge-sharing behavior among global software development (GSD) team members. Using survey data collected from 214 GSD team members, we identify three organizational media affordances based on prior affordance literature: awareness, searchability, and editability. Positive relationships are found between perceived media affordances and actualized media affordances. Two actualized affordance

Shared experience (i.e., experience working together) among project team members is known to affect a project team's performance. Yet, little is known of whether the effects of shared experience homogeneous. We empirically find that the effects of shared experience on a project's performance vary by the outcome of shared experience (e.g., successful vs. unsuccessful) as well as project team role (e.g., project managers vs. non-managers) in the context of software development. Moreover, we find t

While healthcare providers have widely adopted digital health platforms for patient online virtual consultations, organizations are challenged by difficulties in utilizing them for effective physician–patient interactions. This study investigates online virtual consultations between physicians and patients enabled by their joint use of mobile social media technology. Based on affordance theory, we propose a new type of group-level affordance, interactive affordance, characterized by interactions

For the successful and sustainable deployment and diffusion of smart factories, both the capabilities of the adopters who operate the factories and the capabilities of the suppliers who supply information technology and equipment play very important roles. However, since the existing models for diagnosing the capabilities of smart factories are mainly focused on evaluating the capabilities of the manufacturing companies themselves, such as technological capabilities and digital transformation, t

Shared experience (i.e., experience working together in prior projects) among project team members is known to affect the project team’s performance. However, little is known of whether this effect is moderated by other factors. In this study, we examine the two attributes of shared experience as moderators: the outcome of shared experience and the time lapse of shared experience. We find that the effect of shared experience on project performance shows an inverse U-shaped curve with respect t

Managing software development is a very complex activity because it must deal with people, organizations, technologies, and business processes. My dissertation consists of three studies that examine software development management from various perspectives. The first study empirically investigates the impacts of prior experience with similar projects (i.e., learning effects) and the impact of the length of time between similar projects (i.e., forgetting effects) on software development project p

This study empirically examines a question often debated in practice: which professional type - specialists, those with deep and focused experience of a particular knowledge, and generalists, who have experience with a broad range of knowledge - contributes more to software development productivity? In order to find an answer to this question, this study investigates the impacts of specialized experience (i.e., prior experience with the focal knowledge), diverse experience (i.e., prior experienc

The rapid advancement of digital technology and growing interest in well-being have fueled the mobile health (mHealth) market. mHealth apps aim to support positive behavioral changes and maintain high user motivation through various health-related activities. This study examines the impact of a gain-loss incentive structure within mHealth apps, where users make a monetary deposit that could result in rewards, penalties, or neither, based on performance. Using data from a leading mHealth app plat

<sec> <title>BACKGROUND</title> Integrative internet social media platform (IISMP) integrates the features of mobile and social media technologies as well as the legacy healthcare systems to support healthcare processes for patients and physicians that enables patient-centered care. To better understand the use of IISMP, especially the digital interactions between patients and physicians, we develop the concept of interactive affordance and use a mixed-method approach to identify and present the
