This capstone project is a protocol intended for researchers conducting qualitative sociotechnical research on data science in the public sector. Its purpose is twofold. First, to design an interpretive qualitative study to further understanding of the as-of-yet understudied area of data science workers who operate in the public sector. Second, to produce a protocol that addresses persistent challenges in transparency within qualitative sociotechnical research by providing a toolkit for doing open, credible, and reproducible collection and analysis of qualitative data. As with data science research itself, this protocol borrows from multiple disciplines to allow for a high degree of usability.
