Given the current data on how software engineers are working together with their leader, you will most likely find a lot of data that is outdated or not focused on the software engineering part. Behavioral Software Engineering tries to change the focus to the software engineering part. The path is hard though because the information for this topic is sparse. This bachelors thesis contributes to the few sources out there who try to understand how software engineers are coping with the leadership styles of their leaders. By analyzing the personality traits of two teams and comparing them to the different leadership styles I am trying to outline what the styles and traits have in common and how they are interacting with each other. This will help team leaders understand their leadership style and how they are affecting their team with their behavior.
