Depth interview

Qualitative marketing research involves a natural or observational abnormal pangit examination of the philosophies that govern consumer behavior. The direction and framework of the research is often revised as new information is gained, allowing the researcher to evaluate issues and subjects in an in-depth manner. The quality of the research produced is heavily dependent on the skills of the researcher and is easily influenced by researcher bias.

Qualitative marketing researchers collect data ranging from focus group, case study, participation observation, innovation game and individual depth interview.

The focus group is marketing research technique for qualitative data that involves a small group of people (6-10) that share a common set characteristics (demographics, attitudes, etc.) and participate in a discussion of predetermined topics led by a moderator. There are opportunities to conduct focus groups with the use of focus group software. There are many types of focus group as well, but they always involve discussion among the group(s). The problem of the focus group is the issue of observer dependency: the results obtained are influenced by the researcher or his own reading of the group's discussion, raising questions of validity. Non-verbal cues, which may contradict the views participants articulate, are important and can easily be missed if the researcher is not familiar with visual cues, body language and other non verbal cues.

Qualitative case study methodology provides tools for researchers to study complex phenomena within their contexts. Because it only studies one case, so it is very up-close, in-depth. It contains high levels of internal validity (the extent to which one is able to say that no other variables except the one being studied caused the result), but the external validity is low. Customer behaviour is a good example for qualitative market research.

Participation observation is watching participants' behavior in real world settings without trying to manipulate their actions. This method is high in external validity but low in internal validity.

Innovation game refers to a form of primary market research developed by Luke Hohmann where customers play a set of directed games as a means of generating feedback about a product or service. A facilitator explains the game(s) to be played and controls the paces, monitors the participants' levels and manages the time. There are many types of innovation games, such as 20/20 vision, me and my shadow, and buy a feature.

By doing individual depth interviews, one can get unique points from each respondent, and their answers will not be influenced by other people as in a focus group.
