Purpose - The purpose of this study is to examine a mobile delivery system as a working ubiquitous decision support system (UDSS) and determine whether it would improve decision quality. Design/methodology/approach - Ubiquitous mobility and context awareness are the two core functions of the UDSS. Hence the authors examined how they might influence individual absorptive capacity and perceived usefulness. Moreover the authors investigated how individual absorptive capacity and perceived usefulness might be related to decision quality. A total of 174 completed questionnaires were collected from delivery workers, and a financial incentive was provided to participants. To test the hypotheses the research model was analysed with the partial least square method. Findings - The results reveal that all paths are statistically valid. Individual absorptive capacity and perceived usefulness were positively influenced by ubiquitous mobility and context awareness. In addition individual absorptive capacity and perceived usefulness have positive effects on decision quality. Research limitations/implications - This research model did not consider all the capabilities enabled by the UDSS. Future study should pay attention to nomadicity, proactiveness, invisibility, and portability as relevant antecedents within the model. Originality/value - In the field of IS studies the impact of the UDSS on users' decision quality has remained unclear to date. The authors adopted a mobile delivery system as a working UDSS and applied it in their study. Thereby the authors found the mediating effects of perceived usefulness and absorptive capacity under a ubiquitous environment. © Emerald Group Publishing Limited.

Agile methods are highly attractive for small projects, but no agile method works well as a standalone system. Therefore, some adaption or customization is always required. In this paper, the Agile Framework for Small Projects (AFSP) was applied to four industry cases. The AFSP provides a structured way for software organizations to adopt agile practices and evaluate the results. The framework includes an extended Scrum process and agile practices, which are based on agility and critical success factors in agile software projects that are selected from Scrum, XP, FDD, DSDM and Crystal Clear. AFSP also helps software managers and developers effectively use agile engineering techniques throughout the software development lifecycle. The case study projects were evaluated on the basis of risk-based agility factors, the agility of the adopted practices, agile adoption levels, and the degree of the agile project success. The analysis of the results showed that the framework used in the aforementioned cases was effective. © 2013 KIPS.

Globalization is a key challenge in the modern software industry. It covers issues like developing software in joint teams all around the world or developing software that needs to be used in many different countries and different cultural environments. In this tutorial, we focus on this second aspect of globalization: developing software, in particular variants of software for markets around the world. PLE4G was designed as a special approach to enrich classical product line engineering with considerations of globalization issues. As we will assume that participants are mostly familiar with the basics of product line engineering, we will focus in particular on those issues that are specific to globalization.

The purpose of this study is to analyse various factors of switching blogs. The switching costs theory has been applied to develop the research model. Bloggers using such blogs as: Cyworld's minihompy, Naver's blog, Daum's Tistory, and Tattertools were selected as subjects for the sample frame. A total of 290 surveys were collected, from which 243 were used as data for analysis. Results of the survey by SPSS 12.0 showed that the attractiveness of alternatives and attachment affected blog switching intention, and attractiveness of alternatives had a moderating effect between user satisfaction and switching intention.
