This document provides an overview of ethnography and how it can be applied in various contexts. It discusses ethnography as the study of people in their natural environments through observation and informal interviews. It also outlines important principles for conducting ethnographic research, such as being unassuming, using all five senses to make observations, spending enough time with subjects, and preparing properly with checklists, recording devices, and consent forms. Finally, it notes how ethnography differs from traditional market research by being more holistic, contextual, and empirical in its approach to understanding human behavior.
