We chose a facilitated survey format for this interview combining engineering domain expertise with sociology research methods both quantitative and qualitative. The sample size, n, was between 30 and 55 for individual questions depending on the company. The sample size and interview length were targeted for a mix of breadth and depth allowing for a broader understanding than what typical case studies allow as well as a deeper analysis than the scope of typical surveys. This unique study provides a new "bottom-up", interdisciplinary, and mixed-methods perspective on the hardware PD process.
