The participants in a study can become involved in the research process to an extent that may be beyond the past experience of the researcher.The rapport necessary to carry out in-depth case studies places a great deal of responsibility on develop a strong rapport with s while remaining the researcher removed from the situation. This can more difficult than originally assumed helps if the researcher begins to refer to the end of the fieldwork during Phase 2 to make it clear to participants that the work with them will come to an end at some point. At the beginning of the fieldwork it helps if each participant is given a stud outline; dates should be included even if they are broad estimates, in order to give the participants a definite picture of the structure of the study. Once it becomes apparent that the fieldwork is not yielding new information the researcher should ell participants that the study will end soon and refer them to the original stud outline
