An example of a successful research proposal: Part II.

In qualitative case study research, the investigator uses open-ended methods of data collection, such as intensive interviews, to gain an understanding of each case. The structure of data collection allows for expected and unexpected relationships to be described. During open-ended interviews, the interviewer is the so-called instrument and must be authentic, intuitive, and receptive to the unfolding story. Open-ended questions support the exploratory and descriptive nature of this study by enabling the investigators to elicit information about a wide variety of situations that would otherwise require a formidable survey questionnaire. In collective case study, common questions facilitate across-case analysis. In addition, using standardized interview guides promotes consistency when more than one interviewer will be involved in performing the interviews.
