Collaborative software design and modeling in virtual reality

Context: Software engineering is becoming more and more distributed. Developers and other stakeholders are often located in different locations, departments, and countries and operating within different time zones. Most online software design and modeling tools are not adequate for distributed collaboration since they do not support awareness and lack features for effective communication. Objective: The aim of our research is to support distributed software design activities in Virtual Reality (VR). Method: Using design science research methodology, we design and evaluate a tool for collaborative design in VR. We evaluate the collaboration efficiency and recall of design information when using the VR software design environment compared to a non-VR software design environment. Moreover, we collect the perceptions and preferences of users to explore the opportunities and challenges that were incurred by using the VR software design environment. Results: We find that there is no significant difference in the efficiency and recall of design information when using the VR compared to the non-VR environment. Furthermore, we find that developers are more satisfied with collaboration in VR. Conclusion: The results of our research and similar studies show that working in VR is not yet faster or more efficient than working on standard desktops. It is very important to improve the interface in VR (gestures with haptics, keyboard and voice input), as confirmed by the difference in results between the first and second evaluation

Software engineering whispers: The effect of textual vs. graphical software design descriptions on software design communication

Context:\ua0Software\ua0engineering\ua0is a social and collaborative activity. Communicating and sharing knowledge between\ua0software\ua0developers requires much effort. Hence, the quality of\ua0communication\ua0plays an important role in influencing project success. To better understand the\ua0effect\ua0of\ua0communication\ua0on project success, more in-depth empirical studies investigating this phenomenon are needed. Objective: We investigate the\ua0effect\ua0of using a\ua0graphical\ua0versus\ua0textual\ua0design\ua0description\ua0on co-located\ua0software\ua0design\ua0communication. Method: Therefore, we conducted a family of experiments involving a mix of 240\ua0software\ua0engineering\ua0students from four universities. We examined how different\ua0design\ua0representations (i.e.,\ua0graphical\ua0vs.\ua0textual) affect the ability to Explain, Understand, Recall, and Actively Communicate knowledge. Results: We found that the\ua0graphical\ua0design\ua0description\ua0is better than the\ua0textual\ua0in promoting Active Discussion between developers and improving the Recall of\ua0design\ua0details. Furthermore, compared to its unaltered version, a well-organized and motivated\ua0textual\ua0design\ua0description–that is used for the same amount of time–enhances the recall of\ua0design\ua0details and increases the amount of active discussions at the cost of reducing the perceived quality of explaining

The influence of software design representation on the design communication of teams with diverse personalities

Software is the main driver of added-value in many of the systems that surround us. While its complexity is increasing, so is the diversity of systems driven by software. To meet the challenges emerging from this combination, it is necessary to mobilize increasingly large and heterogeneous multidisciplinary teams, comprising software experts, as well as experts from various domains related to the systems driven by software. Hence, the quality of communication about software between stakeholders of different domains and with different personalities is becoming a key issue for successfully engineering software-intensive systems. The goal of this study, thus, is to investigate the effect of the representation of software design models on the communication of design decisions between stakeholders with diverse personality traits. As a result, this study finds that graphical representations of software design models are better than textual representations in enhancing the communication and increasing the productivity of stakeholders with diverse personalities
