Open source software development (OSSD) process modeling has received increasing interest in recent years. These efforts aim to identify common elements in the development process between multiple open source software (OSS) projects. However, the complexity inherent to OSSD process modeling puts significant demands on the modeling language.
Objective

In this paper, we propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed.
Method

We investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. DEMO models were constructed to describe the NetBeans Requirements and Release process. In addition, the quality of these DEMO models was evaluated using a quality framework for conceptual modeling.
Results

Our results showed that our DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. In addition, the evaluation of the models developed in this paper by using the quality framework for conceptual modeling showed that the models were of high quality.
Conclusions

We have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models. However, given some potential drawbacks with respect to understandability and implementability, we primarily propose the use of DEMO within OSSD process modeling as an analysis tool that should be complemented with other techniques and models for communication and reenactment purposes.},

	abstract = {IT managers seem to be hesitant to adopt OSS in the absence of professional support. Previous qualitative studies have indeed suggested that the availability of external support is important for the adoption of OSS. Therefore, we feel it is interesting to gain more insight into the role of external support in the adoption process. To this end, we performed a web survey involving 95 Belgian organizations. Our data suggests a balanced picture. As expected, our results show that the majority of organizations in our sample rely on commercial support such as vendor or third party support. Even organizations that have deployed OSS to a large extent{\textemdash}and that are therefore likely to have some experience and familiarity with OSS{\textemdash}rely on commercial support. Nevertheless, a considerable proportion of organizations indicated not to rely on commercial support, which suggests that internal expertise can be sufficient for successful adoption. Finally, and most surprisingly, we have found that the OSS community is used by a large proportion of organizations. This indicates that the OSS community is a valuable source of external support for organizations. Nevertheless, it appears that it is primarily used by organizations with a rather strong background in IT.

	abstract = {Open source software is increasingly used by public administrations as an alternative to commercial software. In this paper we present a case study of the transition of the ministerial cabinets of the Brussels-Capital Region towards OpenOffice.org. 
In this case, the decision to use open source software was taken by the Government of the Brussels-Capital Region. The goal of the paper is to outline the implementation trajectory followed and to compare our findings to previous studies in this field as well as other Information Systems literature. Additionally, we discuss how OpenOffice.org was received by end users as well as the IT department that was responsible for the migration. Our findings indicate that although a migration towards OpenOffice.org is feasible, a number of difficulties still remain. For example, end user perceptions of OpenOffice.org are not always favorable and migration costs (document conversion and training) can be significant.

	abstract = {This study reports on five case studies in Belgian organizations that currently use open source server software. Respondents were asked about their motivation to use open source server software. Our results indicate that the lower cost, high reliability and availability of external support are the prime reasons why organizations use open source software. The often claimed advantage of open source software of having access to the source code was found relevant only for those organizations who perform development based on open source software. Some factors that were found relevant in previous studies (such as the support of standards) were however deemed less important by the organizations in our sample.

The design and operation of this website is inspired by the Open Source movement and recent developments such as Wikipedia. In operations research, data sets are exchanged between researchers in order to test the performance of newly developed algorithms. Currently, the exchange of these data sets suffers from many problems. One of the main problems is that data sets are currently exchanged through a centrally maintained website, which makes it slow to respond to new developments. By applying an Open Source approach to content creation, we hope to spur the diffusion of information within the operations research community.},

	abstract = {Many studies on Open Source Software Development (OSSD) have been published in the past years. In these studies, OSSD has received positive comments and is proposed as a new way of developing software. We investigate how project management is used in Open Source Software (OSS) projects to exercise control of development activities. Project management in OSSD is worth studying, because research has shown that project management is a critical success factor in traditional software development. We use the COBIT framework to audit project management practices commonly found in OSS projects with the aim of determining which practices are currently missing or can be further improved upon. The framework identifies several potential threats to the long term continuity of OSS projects.},
