Date: Jan 25,2010 Editor: QYResearch Consutling Research Lab

QYResearch used to deal with several difficult custom research projects need depth interviews,here we share our experience for customers or consulting craft brothers:

According market survey or first hand data source, we often use interviews in order to get true and reliable data or information. and generally, normal market survey need Statistical theory model + data acquisition and analysis mode.but we do not discuss this kind survey at this paper, here we discuss depth interview or professional interview as these interviews seldom or almost not use any Statistical theory model. it only rely on interviews, such as handset manufacturing process survey or BOM survey. it is not easy to get the related information or data via Statistical theory model.So, we can only get the target information via professional interviews.generally professional interview just like normal interviews also divided into phone interview and spot interview.spot interview cost higher than phone interviews, So phone interview is popular. and this kind of professional interview need Interviewer and Interviewee have rich experience at the same industry,such as handset manufacturing process and BOM, Amateur can not do the interview and Interviewee will also no interesting to accept a amateur Interviewer.what is more, as most depth interviewee are stranger,so all market survey or interview should obey law and societ marol.and generally Interviewer should pay for Interviewee for about 100-500USD/Hour via phone or face to fact interviews.

here we discuss how to get the information via professional interviews, such as handset manufacturing process cost structure and BOM survey. the data or information maybe not control by one person or few persons, and maybe the inside workers also do not know all of related information, thus. interviewer should do the interview with several steps, first step,interview technical or process engineer who has rich experience on handset manufacturing,. second step, interview dirctor of each department through handset manufacturing process,in order to know BOM details labour cost equipment cost etc. third step,after the previous two steps, we can know all information and data from the company itself, but we can not confirm it is right or wrong, so we need double check the data or information through other parts, generally, we will interview their upstream suppliers and downstream customers, such as raw material suppliers and equipment suppliers, and their customers. thus we can get the same data or information through three voices and three voices from different companies, we usually it can get relliable enough information if the three steps completed. and also reach our survey targets.

as limitation of this paper, QYResearch will not introduced details of the case and also there are a lot of uncertain factors during phone or spot interviews,So we just list a method and details steps should carry out according different projects or persons, but one point is same, that is this kind of interviews should do by professional experts.in Solar and wind energy, QYResearch has rich experience and owned experience to do this kind of survey,other industries,QYResearch is an amateur.here just list a topic,also looking forward your opinions and advices.
