Here is a topic that is worthy of more discussion in the research community: What is the optimal number of in-depth interviews to complete in an IDI study? The appropriate number of interviews to conduct for a face-to-face IDI study needs to be considered at two key moments of time in the research process – the initial research design phase and the phase of field execution. At the initial design stage, the number of IDIs is dictated by four considerations: 1) the breadth, depth, and nature of the research topic or issue; 2) the hetero- or homogeneity of the population of interest; 3) the level of analysis and interpretation required to meet research objectives; and 4) practical parameters such as the availability and access to interviewees, travel and other logistics associated with conducting face-to-face interviews, as well as the budget or financial resources. These four factors present the researcher with the difficult task of balancing the specific realities of the research components while estimating the optimal number of interviews to conduct. Although the number of required interviews tends to move in direct step with the level of diversity and Read Full Text
The researcher’s key to the executive suite is hanging in the spot where it has always been. Our entry into the consumer and other B2B worlds may have strayed towards mobile and online methods – bulletin boards, surveys, communities, and social-media lurking – but successful research with the corporate executive still lies in the warm, personal connections we make in the face-to-face mode. We can try to defend other approaches as more efficient (in time and cost), innovative, and sexy, but the reality is that nothing reaps the richness of a person (the professional interviewer) sitting with another person (the executive interviewee) for the sole purpose of exploring topic-specific attitudes and behavior.
If success is measured by the depth of input and insight then there are at least six necessary components to the face-to-face executive interviewing design model: Read Full Text
