The longitudinal method: study of the change process in qualitative studies in management sciences

Abstract

Considered as one of the tools available to the researcher to understand and analyze the process and course of phenomena, the longitudinal qualitative study remains, despite its importance, an ignored research protocol and is rarely used in management sciences. This contribution aims to provide clarification elements regarding the definition, typology, data collection methods and analysis of results in longitudinal qualitative research. It provides a helpful guide for conducting and reviewing longitudinal studies in these sciences.
