Frequent debriefing sessions between the researcher and his supervisor were important in ensuring credibility of the research process. Through discussion, the vision of the investigator was widened so as other bring to bear other experiences and perceptions. Such Collaborative sessions were used to discuss alternative approaches, and those responsible for the supervision of the study were able to draw attention to flaws in the proposed course of action. The meetings also provided an avenue for the researcher to test his developing ideas and interpretations and allowed for the recognition of his own biases and preferences.
