Data warehouses (DW) form the backbone of data integration that is necessary for analytical applications, and play important roles in the information technology landscape of many industries. We introduce an approach for addressing the fundamental problem of semantic heterogeneity in the design of data integration requirements during DW development....

The building of shared understanding between project stakeholders in the requirements elicitation phase is necessary for knowledge sharing and a key factor for successful information systems (IS) development. However, the processes that lead to shared understanding and successful knowledge sharing are still not well understood. We examine how stake...

Research on IS success and IT adoption has shown that object-based beliefs about IT systems have a profound impact on subsequent IT usage. However, we still lack knowledge on and need to identify antecedents and determinants of object-based beliefs in order to understand how the belief formation process works and how it can be influenced. Our resea...

Methods for Agile information systems development (ISD) are widely accepted in industry. One key difference in comparison to traditional, plan-driven ISD approaches is that Agile ISD teams rely heavily on direct, informal face-to- face communication instead of indirect and formal documents, models, and plans. While the importance of communication i...

Knowledge transfer, communication, and shared understanding between project stakeholders are important factors in requirements development and in the information systems development process.

While extant research on routines largely builds on qualitative methods, the increasing ubiquitousness and prevalence of trace data enables novel methodologi...

Digital ventures must navigate a key tension as they design new digital market offerings—that is, products or services that are embodied in digital technologies or enabled by them. On one hand, digital ventures pursue a vision that builds on what might be possible through the generative potential that digital technology offers, but on the other han...

Research suggests the relationship between time pressure and software quality to be more complex than presumed. While software developers can adjust their output to improve observed performance at the expense of software quality, the latter has been found to increase with time pressure in case of work-pace dependent incentives. An untested, but wid...

One constitutional part of project management is the management of teams, their actions, and their social mechanisms. Team processes, behavior, and agile practices used by team members play important parts in the success of projects. To reap benefits from these highly interactive and social-focused practices, team members need to feel safe to speak...

Agile methods are increasingly popular-in information system development and in general. The process of transformation hard and the inherent barriers for successful transformation are high. To successfully transform a team or a whole organization, the threats, barriers and the overall process have to be known. In this paper, we derive a lifecycle m...
