Grounded theory (the practice of developing other theories that emerge from observing a group) is a typical approach to the analysis and interpretation of ethnographic research and is discussed in greater detail in Part 4. The aim is not to create universal ‘laws’ but localized theory relating to the specific phenomenon. Theory emerges from local site and the background analysis of the context; this adds to theory from other sites, other researchers and the theory building continues as an ever increasing understanding of concepts by repeated, in-depth exploration.
