Enterprise System Renewal - The Divergence Between Perception and Reality

E-commerce based companies rely on the effective use of the information systems used to support their processes. Accordingly, managers place a great emphasis on the success of projects to introduce such systems. However, research increasingly suggests that project success may not be as objective as one would assume or hope. Quite contrary, as our work will show, project success is often constructed by the stakeholders involved in the project. Extending prior research, we investigate how different groups of stakeholders construct their own perception of project success and how these different perceptions influence each other. Through our work, we provide management with insights into threats to a reliable project management approach for critical IS projects and identify a few major drivers that need to be accounted for to make sure that such critical projects really are successful

Understanding Effective Use in the (Post)-Implementation Phase of Information Systems

Organizational information systems (IS) must be used effectively to maximize their benefits for the overall organization. However, their complexity creates significant challenges for conducting the IS project of an implementation in such a way that users are subsequently enabled to use a system effec-tively. The challenge is also present in the post-implementation phase whenever employees have to learn how to use a system effectively for a given task and develop their own adaptations. Thus, this thesis presents a research effort on the means that effect users’ perception and ability to use a system effec-tively during an IS project as well as in the phase of use in post-implementation. Thereby this thesis provides a more detailed understanding of the concept of effective use and the conditions that enable effective use of IS. The analysis of IS projects contributes to research on the ambiguous and subjective nature of the evaluation of IS project success and explores the configuration of user involvement and participation in implementation projects that is most likely to be related to project success. The results of the analysis show that the participation of the appropriate users in the requirements analysis phase is most often related with IS users that feel enabled to use an IS effectively. Research on the IS use in the post-implementation phase presented in this thesis provides more detailed conceptual development of the relationship of user behaviors such as learning, user adaptation, and workarounds with effective use and thereby extents the nomological net of theory of effective use (Burton-Jones & Grange, 2013). Results of further analysis show that workarounds can positively affect the use of an implemented IS. Finally, this thesis contributes an operationalization of the concept of effective use based on the initial conceptualization by Burton-Jones and Grange (2013). This answers a call for research on richer concep-tualizations of IS use. In sum, these findings add to research on concept of IS use and user behaviors that influence the effective use of IS. Therefore, they enable a more detailed understanding of the concept of effective use and allow future researchers to extent and refine the nomological net of effec-tive use. Practitioners may also employ these new measures to measure the effectiveness of their efforts to improve the effective use of IS. They also benefit from the insights on the perception of IS success in organization and appropriate phases and forms of user participation in IS projects
