This chapter will focus on the participant observation method as one of the data collection tools for corporate social responsibility (CSR) research and it will present information oriented towards how we can use especially the participant observation method in our research. When we approach the issue in methodological terms, observation is a tool that can provide us with important data resources within the method that we chose based on the research problem. Conducting a study based on qualitative study principles requires detailed planning and acting accordingly. The use of ethnography in a study in organizations is often performed as a part of a grounded theoretical framework, a sound research design, data collection tools, effective analysis methods and validity-reliability calculations. Research design starts with the determination of the research question and related questions thereto, and then follows a cyclical process. Researchers choose among these options depending on their research design.Although it is believed that providing detailed information about these tools will be useful to guide researchers, who are planning to apply quantitative research methods, it will increase the length of this chapter considerably. With these techniques, the participant observation method, which is considered as almost equaling ethnography, will form our fundamental discussion point for this chapter.
