F.G. is one of the best and currently applied instruments in qualitative researches. In This research, We have one main Subject and it will be the focus of discussion in the selected group. At first. P. Lazarsfeld used this method. We can use F.G. as an exploratory research. We can use it at the end of a research, but, it is possible to use F.G. as an independent tool. When we use this method we have to observe many considerations: At first, we have to determine the dimensions of the subject. Then, we have to select a participant for each dimension. We have to define the competency criteria for each participant, More over, we have to select a competent monitor. Time management and assessment of any participant is also necessary. We call it a posteriori evaluation .F.G as a tool has many privileges but it has some bottlenecks :F. G, is applied in a specific culture therefore, any problem related to the culture will be reflected in the validity of data obtained by this instrument. However, This tool is a useful one in conducting social research.
