Abstract

SOCIAL NETWORKS ARE COMMONLY USED IN PRIVATE AND BUSINESS LIFE. DIFFERENT STUDIES OUTLINE THAT THIS TREND WILL INCREASE IN THE NEARER FUTURE. IN ORDER TO UNDERSTAND THE BEHAVIORAL INTENTION TO PARTICIPATE IN SOCIAL NETWORKS OF NEXT GENERATION EMPLOYEES, WE EXTENDED THE WELL-ESTABLISHED THEORY OF PLANNED BEHAVIOUR TO HABIT AND INFORMATION OVERLOAD. USING SURVEY DATA FROM 262 PARTICIPANTS, WE FOUND THAT THE OVERLOAD OF INFORMATION PLAYS AN IMPORTANT ROLE TO PARTICIPATE IN SOCIAL NETWORKS, BESIDES THE HABIT TO USE SUCH NETWORKS.

A Unified View of Electronic Invoicing Adoption: Developing a Meta-Model on the Governmental Level

In: Proceedings of the 46th Hawaii International Conference on System Sciences (HICSS); Los Alamitos, CA, USA

Category: Proceedings [Find it]

Abstract

The digitalization of invoices and their processing is a key factor for the improvement of process efficiency on the G2B (government-to-business) and G2G (government-to-government) level. Some European countries like Denmark or Spain already started to mandate electronic invoicing, but most other countries in the European Union are still in the planning phase for implementation. This weak adoption rate hinders governments to generate benefits of electronic invoicing, so an understanding of this fact from a public sector perspective is crucial. Still, the majority of preceding studies investigated electronic invoicing from a private sector perspective. In addition to that, an overarching model explaining electronic invoicing adoption is still missing. This paper develops a unifying meta-model of influencing factors of electronic invoicing adoption on governmental level by analyzing relevant literature and by conducting expert interviews. The paper then discusses implications for future research with a focus on the public sector.

A Mapping Model for Assessing Project Effort from Requirements

In: Information Systems and e-Business Management (11:3), pp. 377-401

Category: Publications in scientific journals [Find it]

Abstract

Since the effort required to develop a system depends on its requirements, it is important to consider the resulting effort when deciding on the requirements. Miscalculating the effort may lead to requirements that cannot be implemented within given budget constraints. In order to support requirements engineers in calculating the effort resulting from the requirements they elaborate correctly, we develop a mapping model for assessing project effort from requirements (MMAPER) in this paper. MMAPER incorporates effort estimation into requirements engineering and thereby enables engineers to proactively assess project effort without demanding that they spend significant additional time on this task. MMAPER measures system size using function point analysis and assesses the resulting effort using the Constructive Cost Model 2. The theoretical underpinning of the methods stems from theoretical perspectives from which we derive theories of how requirements determine the resulting project effort. We also take into consideration that it is important to distinguish requirements of different size but also implemented in different contexts for estimating the resulting effort. We empirically evaluate the model using data from five case studies which we conducted with a financial services organization. The developed model provides very accurate effort estimations, across both controlled experiments and field applications.
