For very practical purposes, it can be said that qualitative research of scientific nature has three stages: (1) an exploratory phase; (2) fieldwork; (3) analysis and treatment of the empirical and documentary material. The exploratory phase consists of the production of the research project and all the procedures necessary for preparation to enter the field. The fieldwork phase constitutes the primordial moment for understanding, in intersubjectivity, the empirical reality under study.
