Towards a multi-criteria development distribution model: An analysis of existing task distribution approaches

Distributing development tasks in the context of global software development bears both many risks and many opportunities. Nowadays, distributed development is often driven by only a few factors or even just a single factor such as workforce costs. Risks and other relevant factors such as workforce capabilities, the innovation potential of different regions, or cultural factors are often not recognized sufficiently. This could be improved by using empirically-based multi-criteria distribution models. Currently, there is a lack of such decision models for distributing software development work. This article focuses on mechanisms for such decision support. First, requirements for a distribution model are formulated based on needs identified from practice. Then, distribution models from different domains are surveyed, compared, and analyzed in terms of suitability. Finally, research questions and directions for future work are given

A rule-based model for customized risk identification in distributed software development projects

Many project risks in distributed software development are very different from the ones in collocated development and therefore are often overlooked. At the same time, they depend to a large extent on project-specific characteristics. This article presents a model for identifying risks early in a project. This model systematically captures experiences from past projects and is based on a set of logical rules describing how project characteristics influence typical risks in distributed development. Thus, the model is able to assess risks individually for each project. It was developed by applying qualitative content analysis to 19 interviews with practitioners. An evaluation using expert interviews showed that the risks identified by the model matched the actual experiences in 81% of the cases; of these, 40% have not been regarded yet at project start. The article describes the concepts of the model, its instantiation and evaluation, followed by a conclusion and future work

A rule-based model for customized risk identification and evaluation of task assignment alternatives in distributed software development projects

Distributed software development imposes new project risks that are very different from the ones in collocated development and are overlooked easily. At the same time, they depend to a large extent on project-specific characteristics. Therefore, new methods for identifying these risks in distributed projects have to be developed. This article presents a model for identifying these risks at the beginning of a project. The model systematically captures experiences from past projects in a set of logical rules describing how project characteristics influence typical risks in distributed development. Thus, it is able to assess risks individually for each project. In addition, the model can be used for evaluating different task assignment alternatives, which makes it possible to allocate tasks systematically. An instance of the model was developed by applying qualitative content analysis to 19 interviews with practitioners. An evaluation using expert interviews showed that the risks identified by the model matched the actual experiences in 81% of the cases; of these, 40% had not been regarded at project start
