The literature has a mixed response on the usefulness of using a tool like NVivo for the analysis of qualitative data or doing it manually. It allows interrogation and analysis of data at a particular level, allowing engagement with the data, and the derivation of impressions and concepts from it. “The searching tools in NVivo allow the researcher to interrogate her or his data at a particular level. This can, in turn, improve the rigour of the analysis process by validating (or not) some of the researcher’s own impressions of the data.” (Welsh 2002)
