Studying Onboarding to Improve Program Comprehension Tool Support

Gaining an understanding of unfamiliar software systems is hard. Existing support tools are based on studies of the information sought by software developers, but often the developers themselves do not know what to look for. Here an alternative is proposed: by studying the information `pushed' from software experts to new developers during onboarding, the information provided by the experts can be analysed and compared to the information `pulled' by the new developers. The content and presentation of this data will inform tool design for onboarding support.
