The research, however, could not be implemented as conceived. Uncontrollable circumstances and unexpected events undermined the implementation of the study. Perhaps in more favourable circumstances it could be enacted as planned or more active control of the implementation process may have averted some of the unexpected difficulties. Alternatively such a study may be too ambitious. The study process highlighted the great difficulty of conducting research into reliability in situ,
and exemplifies many of the challenges of conducting organisational field research.
