Scaling the Management of Extreme Programming Projects

XP is a code-oriented, light-weight software engineering methodology, suited merely for small-sized teams who develop software that relies on vague or rapidly changing requirements. Being very code-oriented, the discipline of systems engineering knows it as approach of incremental system change. In this contribution, we discuss the enhanced version of a concept on how to extend XP on large scale projects with hundreds of software engineers and programmers, respectively. Previous versions were already presented in [1] and [12]. The basic idea is to apply the "hierarchical approach", a management principle of reorganizing companies, as well as well-known moderation principles to XP project organization. We show similarities between software engineering methods and company reorganization processes and discuss how the elements of the hierarchical approach can improve XP. We provide guidelines on how to scale up XP to very large projects e.g. those common in telecommunication industry and IT technology consultancy firms by using moderation techniques.Comment: 7 pages, 4 figure

Analyse the risks of ad hoc programming in web development and develop a metrics of appropriate tools

Today the World Wide Web has become one of the most powerful tools for business promotion and social networking. As the use of websites and web applications to promote the businesses has increased drastically over the past few years, the complexity of managing them and protecting them from security threats has become a complicated task for the organizations. On the other hand, most of the web projects are at risk and less secure due to lack of quality programming. Although there are plenty of frameworks available for free in the market to improve the quality of programming, most of the programmers use ad hoc programming rather than using frameworks which could save their time and repeated work. The research identifies the different frameworks in PHP and .NET programming, and evaluates their benefits and drawbacks in the web application development. The research aims to help web development companies to minimize the risks involved in developing large web projects and develop a metrics of appropriate frameworks to be used for the specific projects. The study examined the way web applications were developed in different software companies and the advantages of using frameworks while developing them. The findings of the results show that it was not only the experience of developers that motivated them to use frameworks. The major conclusions and recommendations drawn from this research were that the main reasons behind web developers avoiding frameworks are that they are difficult to learn and implement. Also, the motivations factors for programmers towards using frameworks were self-efficiency, habit of learning new things and awareness about the benefits of frameworks. The research recommended companies to use appropriate frameworks to protect their projects against security threats like SQL injection and RSS injectio

Transition of Governance in a Mature Open Software Source Community: Evidence from the Debian Case

As flourishing, productive open source software (OSS) communities mature, they have to introduce a variety of governance mechanisms to manage the participation of their members and to coordinate the launch of new releases. In contrast to other modes of governance of OSS communities, the Debian community introduced new mechanisms of informal administrative control based on a constitution, elected leaders and new functions attributed to interactive communication channels (like mailing lists or IRC channels) that can provide for community effects (and feedback). We show that these control mechanisms were introduced as a response to emerging innovative opportunities due the usage of source packages and heterogeneous learning processes by different groups within the Debian community.Open Source Software community, Governance Mechanism, Debian Community

The Impact of Entry and Competition by Open Source Software on Innovation Activity

This paper presents the stylized facts of open source software innovation and provides empirical evidence on the impact of increased competition by OSS on the innovative activity in the software industry. Furthermore, we introduce a simple formal model that captures the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The paper identifies a pro-innovative effect of OSS competition.open source software, innovation, strategic interaction

Identifying the Enablers and Barriers of Information Technology Personnel Transition

This paper reports the initial findings from a National Science Foundation supported study of IT personnel transition. We used the revealed causal mapping method (Narayanan and Fahey 1990) to elicit barriers, enablers, and examples of IT personnel transition. This paper reveals new knowledge and insight into factors that enable and prevent IT personnel transition as organizations evolve. The data is presented in the form of interpretation of revealed causal maps from 83 respondents. The results of this study are the first steps toward developing a theory of IT personnel transition that is distinct from general transition theories

Global IS research: Cultivating universalistic and situated perspectives in the age of ubiquitous computing

This paper examines the tension between universalistic and situated perspectives particularly in terms of the forces driving each perspective as well as other forces constraining them. This concept is discussed in general, and then applied to a set of specific topics across the range of global IS concerns. The paper includes a discussion of the tension between these perspectives in investigating emerging topics in global IS research and concludes providing some guidance in extending research in this area

Analysis of activity in open-source communities using social network analysis techniques

The success of an open-source software project is closely linked to the successful organization and development of the underlying virtual community. In particular, participation is the most important mechanism by which the development of the project is supported. The main objective of this paper is to analyse the online participation in virtual communities using social network analysis techniques in order to obtain the main patterns of behaviour of users within communities. Several open-source communities related to Linux ports to embedded processors have been studied, obtaining a set of indicators by modelling them as a social network. Exploratory factor analysis has been used to extract the main dimensions related to the participation process. Participation inequality, hierarchy and the cohesion of the community constitute the main dimensions characterizing the participation mechanism within communities. Obtained results highlight the necessity of guiding the organization and development of the community to achieve successful target softwareJunta de Andalucía.
