Ethnomethodology is the study of methods people use for understanding and producing the social order in which they live. It generally seeks to provide an alternative to mainstream sociological approaches. In its most radical form, it poses a challenge to the social sciences as a whole. On the other hand, its early investigations led to the founding of conversation analysis, which has found its own place as an accepted discipline within the academy. According to Psathas, it is possible to distinguish five major approaches within the ethnomethodological family of disciplines.
Ethnomethodology provides methods which have been used in ethnographic studies to produce accounts of people's methods for negotiating everyday situations. It is a fundamentally descriptive discipline which does not engage in the explanation or evaluation of the particular social order undertaken as a topic of study. However, applications have been found within many applied disciplines, such as software design and management studies.
The term's etymology can be broken down into its three constituent parts: ethno - method - ology, for the purpose of explanation. Using an appropriate Southern California example: ethno refers to a particular socio-cultural group [think a particular, localized community of surfers]; method refers to the methods and practices this particular group employs in its everyday activities [related to surfing]; and ology refers to the systematic description of these methods and practices. The focus of the investigation used in our example is the social order of surfing, the ethnomethodological interest is in the "how" [the methods and practices] of the production and maintenance of this social order. In essence ethnomethodology attempts to create classifications of the social actions of individuals within groups through drawing on the experience of the groups directly, without imposing on the setting the opinions of the researcher with regards to social order, as is the case with sociological studies.
The approach was originally developed by Harold Garfinkel, who attributed its origin to his work investigating the conduct of jury members in 1954. His interest was in describing the common sense methods through which members of a jury produce themselves in a jury room as a jury. Thus, their methods for: establishing matters of fact; developing evidence chains; determining the reliability of witness testimony; establishing the organization of speakers in the jury room itself; and determining the guilt or innocence of defendants, etc. are all topics of interest. Such methods serve to constitute the social order of being a juror for the members of the jury, as well as for researchers and other interested parties, in that specific social setting.
