Research Projects

• The effect of multitasking on actual and perceived productivity and code quality
  Developers today have to work on a multitude of projects and tasks. This condition, which forces them to switch context (i.e., different programming languages, toolchains) multiple times over a day, applies to both OSS and paid developers. Yet, the effects of the mental overload associated with such context switchings have on developers’ productivity and the quality of the code they create during multitasking work sessions.
  — Joint research effort with  Bogdan Vasilescu (CMU).
  An industrial replication of the same investigation is being performed at two large companies from Porto Alegre (Brasil)
  — Joint research effort with Rafael Prikladnicki (PUCRS and TECNOPUC).
• Establishing the effect of developers’ personality and trust in distributed software development
  Software is the result of the effort of very many developers, each having their own personality. Because personality influences how a developer interacts with others, understanding the effects of personality variations can help explain some of the intricacies of software development that make it so hard. Among personality traits, trust takes the spotlight, being a factor that can determine the performance of teams, especially in distributed settings. To perform this research, we use psychometric analysis tools, in conjunction with the Big 5 personality theory (or Five-Factor Model), to mine personality from written traces left by developers in the various communication channels used in modern distributed software projects.
• Success factors in online creative communities
  The project aims to identify the fundamental resemblances and differences between the open-source software (OSS) communities and creative arts communities -i.e., seeing software development as a creative activity — and propose solutions to improve both through cross-contamination and ultimately show that deeper cohesion within the community that could lead to better collaboration and artifacts
  — Joint research effort with Igor Steinmacher and Marco Aurelio Gerosa (Northern Arizona University).
• Information fragmentation and overload for DevOps
  Today, an ever-growing plethora of development tools provide a continual stream of updates and place developers in a situation of information fragmentation and overload. This project defines a hub-and-spoke model for the loosely-coupled integration of development tools, which can help developers cope with these issues while also increasing their overall situational awareness
  — In collaboration with the ReCaS-Bari datacenter.
