In 2006 my university academic IT support group was approached by an academic colleague wanting to start a new journal, which would be available in electronic form only. There were restrictions imposed by the technical capabilities of the pool of authors, the requirements of the discipline, and — unsurprisingly — the lack of financial resources. The decision was made to implement a system using only open source software, and building largely from scratch, as the existing open source journal publishing systems at the time, although comprehensive and well-established, were seen as far too large and complex for the task. This paper is a case study describing the process and explaining the background to the decisions made. It attempts to draw some conclusions about the technical viability of creating a small-scale publishing system which attempted to retain XML throughout the workflow, and about the human factors which influenced the decisions.

Software development projects are complex. The more complex a project is, the higher are the requirements related to the software development process. The implementation of a process is a great challenge. This, in part, has to do with human factors (acceptance, etc.) as the benefits of a formal development process might not be obvious immediately and it may take a while until the process becomes the lifeblood of a team. A crucial step towards implementing, enacting and enforcing a process is to provide tool support for the many activities the process asks for. Tool support is necessary to guarantee efficiency in the project, to do the housekeeping and to minimize the “overhead” of the process. This chapter describes challenges and options for supporting process models by tools. Furthermore it describes concrete samples and shows how tool chains can be created with commercial tools as well as with open source tools.

Building an effective team of developers is a complex task faced by both software companies and open source communities. The problem of forming a “dream” team involves many variables, including consideration of human factors, and it is not a dilemma solvable in a mathematical way. Empirical studies might provide interesting insights to explain which factors need to be taken into account in building a team of developers and which levers act to optimise collaboration and productivity among developers. In this paper, we present the results of an empirical study aimed at investigating the link between team diver- sity (i.e., gender, nationality) and productivity (issue fixing time). We consider issues solved from the GHTorrent dataset inferring gender and nationality of each team’s members. We also evaluate the politeness of all comments involved in issue resolution. Results show that higher gender diversity is linked with a lower team average issue fixing time and that nationality diversity is linked with lower team politeness.

Human Factors educators teach a variety of different types of classes including in-person, mixed mode, and online. The Generalized Intelligent Framework for Tutoring (GIFT) is a free, open-source domain-independent intelligent tutoring system (ITS) framework that can be leveraged by Human Factors educators for use in their own classes. GIFT includes authoring tools that are easy to use and do not require a background in computer science or ITSs. This demonstration is interactive and shows an overview of the tools and features of GIFT that can be used by Human Factors educators. It also provides context by showing a GIFT course in a Human Factors relevant area, and discusses how GIFT has and can be used in the classroom. As GIFT is open-source and continually being developed, the presenters provide the conference attendees an opportunity to give feedback about useful improvements that could be made to GIFT.
