Impact of Team Size, Project Scale and Level of Education on Software Build Event Status in Enriched Event Streams

Creating a successful team based on number of developers, previous experience of programmer, and their level of education has been a topic of research for decades. Some studies suggest small size teams are better, while others find larger teams more successful. In addition, large projects are more complicated and more error prone. Discovery of the optimal values for these factors in software engineering is always considered as a major challenge. This paper examined the size of the team and scale of project and the level of education of developers on the status of Build events of software based on 11 million actual interactions performed by 83 programmers in a dataset called Enriched Event Streams dataset. The programmers had various programming skills and used variety of programming languages. The results based on 15,000 hours of development activity log indicate that the optimal size of the team is medium size, with developers engaged in large scaled projects without graduate degrees from universities. In other words, experience in large scale projects provides more advantages in contrast to graduate education that has negative impact on programming skills.
