Group feedback analysis applied to longitudinal monitoring of the decision making process

The paper describes the application to longitudinal research of a method of data collection which combines quantitative and qualitative material. It is claimed that Group Feedback Analysis (GFA) helps to validate data collected by various methods and produces additional ethnographic material and insight into the process under investigation. When the people who supply the data are experienced in the subject matter, as is the case with managers and other employees in organizational research, GFA makes it possible for them to help with the interpretation of the data instead of leaving it entirely to the researcher. The method, which has previously been used in cross-sectional research, is shown to have utility in a longitudinal design where it can facilitate organizational learning. It can also contribute to the refinement of a theoretical model
