One example of the company's ethnographic research in action was provided by a project commissioned by the footwear brand Dr Martens. It wanted to understand how young people used fashion brands in their every lives . Why for example, did some brands, such as Nike trainers or baseball caps become popular in youth culture? The researchers identified groups of young people around the world who responded to Dr Martens' target market. In return for a payment, volunteers were followed for several days and their daily routines filmed with a handheld digital camera. In total, 180 hours of captured film was edited to just one hour of highlights showing the key drivers of youth culture which are relevant to the Dr Martens brand. It seemed that young people preferred fashions that allowed them to customize an item of clothing and in some way take ownership of it. The research drew the conclusion that iconic fashion items for young people had to have a distinctive label or style that made their wearers stand out as part of a tribe. Hence, ethnographic research seems to help this company to know why the young clients choose to buy other brand sport shoes, it is possible that they the other brands sport shoes' color or design can be accepted more to than to buy Dr Marten brand's sport shoes when they wear different style of clothing. Hence, it can use digital camera to observe the worldwide choice of paying target youth volunteers whose daily individual behaviors at homes to get the more actual evidence to evaluate what factors influence youth clients choose to buy other brands of sport shoes. Otherwise, if it use structured questionnaire surveys to enquire youth clients, it is possible that who can not give their feedbacks honestly. Otherwise, observable youth people whose daily activities can help this company to know it is possible that their design and color of clothing are one factor to influence their choice to buy preferable brands of sport shoes to wear if who felt the brand of sport shoe was suitable to wear to influence their clothing to be felt more smart in appearance. However, I suggest companies to avoid to tell householders what the research project is about, until it is over. That way, the chances of participants deliberately playing to the camera can be reduced. Hence, ethnographic researcher ought not tell to participants why who needs to record their daily activities at home till to the end of observable survey finishing due to it is possible that the participants will not perform their actual behaviors if who knew the researcher's observable intention. However, if marketers need to understand how whose companies clients actually make purchase decisions to their products, who shall use structured questionnaire surveys for collecting large scale factual data, but it will have major weaknesses when companies can not understand individual's attitude. Complex sets of factors that influence their buying decisions can only rarely be captured by a questionnaire.
