This is technical anthropology, and it is thorough and much better than you'd expect from a potentially dry dissertation from 1990, described as an “underground classic among ethnographers of work”. The central thesis of the book is that (technical) knowledge is a socially distributed resource that is transported by way of oral culture and that debugging works by constructing a narrative between technician, customer and machine. More details below, but this is both a central insight, well described and documented, and applicable to most areas of (work) life.
