Glaser and Strauss define a grounded theory as being one that will be 'readily applicable to and indicated by the data' and 'be meaningfully relevant to and be able to explain the behavior under study' (Glaser and Strauss, 1967,3). Grounded theory is not a research method, it is a process for the logical analysis of qualitative data. However, there are a number of 'guiding principles', which need to be followed if any researcher wishes to claim they have used grounded theory in their work it, engage in active discovery allowing the data to speak and not be forced.
