Pair dynamics in team collaboration

From a recent field survey with a group of professional pair programmers, it was revealed that the programmers perceive a partner’s personality, cognitive style and communication skills as the top three factors that lead to prudent pair programming. Based on this finding, the factors personality and communication skills, along with gender were selected for an experiment to analyze if a partner’s human, intrinsic values influence the pair programming experience, specifically in the levels of satisfaction, compatibility, communication, and confidence. A total of 128 students majoring in Management Information Systems, Information Systems, and Information Technology participated in the experiment. Of the 68 undergraduates, 40 were first-year students and 28 were juniors; the remaining 60 were Master’s degree graduate students. The students were formed into a total of 64 pairs based on their personality, level of communication skills, and gender. A total of three visits were made. During the first two visits, a set of four programming problems was used in four programming sessions lasting 45 min each; two were individual programming sessions and two were pair programming sessions. At the end of each visit, a questionnaire was administered and collected. The questionnaire results revealed that the various Myers–Briggs Type Indicator (MBTI) personality combinations did not significantly influence the levels of communication, satisfaction, confidence, and compatibility. The pairs that exhibited a high level of communication between partners did not necessarily experience a high level of satisfaction or exhibit compatibility between partners, nor did they have a high level of confidence regarding the finished product. The communication skill level seemed to have an impact on communication only. Similar to many previous gender-focused literatures, the same gender pairs did exhibit significantly higher levels of communication, satisfaction and compatibility than the mixed gender pairs. Within the same gender pairs, the female–female pairs showed a much higher level than the male–male pairs in those categories. Contrariwise, the same gender pairs did not show a significantly higher confidence level than the mixed gender pairs about their finished product.     

An Ontology-based System to Support Distributed Software Development

Distributed software development has become an option for software companies to expand their horizons and work with geographically dispersed teams, exploiting the advantages brought by this approach. However, this way of developing software enables new challenges to arise, such as the inexistence of a formal, normalized model of a project＇s data and artifacts accessible to all the individuals involved, which makes it harder for them to communicate, understand each other and what is specified on the project＇s artifacts. With what being said, this paper proposes a knowledge management tool that utilizes a domain-specific ontology for distributed development environments, aiming to help distributed teams overcome the challenges brought by this modality of software development proposing techniques and best practices. Thus, the main output of this work is ontology-based system to support the software development process with distributed teams.     

Distributed modeling of use case diagrams with a method based on think-pair-square: Results from two controlled experiments

Objective: In this paper, we present the results of two controlled experiments conducted to assess a new method based on think-pair-square in the distributed modeling of use case diagrams.Methods: This new method has been implemented within an integrated environment, which allows distributed synchronous modeling and communication among team members. To study the effect of the participants׳ familiarity with the method and the integrated environment, the second experiment is a replication conducted with the same participants as the original experiment. The results show a significant difference in favor of face-to-face (i.e., the chosen baseline) for the time to complete modeling tasks, with no significant impact on the quality of the produced models.Results: The results on participants׳ familiarity indicate a significant effect on the task completion time (i.e., more familiar participants spent less time), with no significant impact on quality.Practice: One of the most interesting practical implications of our study is - in case the time difference is not an issue, but moving people might be a problem, the new method and environment could represent a viable alternative to face-to-face. Another significant result is that also people not perfectly trained on our method and environment may benefit from their use: the training phase could be shortened or skipped. In addition, face-to-face is less prone to consolidate participants׳ working style and to develop a shared working habit of participants.Implications: This work is in the direction of the media-effect theories applied to requirements engineering. The results indicate that the participants in the experiments significantly spent less time when modeling use case diagrams using face-to-face. Conversely, no significant difference was observed on the quality of the artifacts produced by the participants in the these tasks.
