This research paper by Khairul Baharein Mohd Noor from Universiti Industri Selangor, Malaysia, reviews the literature on case studies as a strategic qualitative research methodology. Despite criticisms of case studies for lacking scientific rigor and generalizability, the author argues that case studies are particularly suitable for in-depth analysis of complex real-life processes and activities. The paper highlights the strengths and weaknesses of case study methods, emphasizing their ability to provide holistic views and capture emergent properties of organizational life. The research methodology chosen for this study is a descriptive case study, involving four organizations. The process includes extensive literature review, theoretical framework development, and the use of semi-structured interviews, participant observation, and documentary sources. The paper also discusses the importance of multiple case studies to enhance generalizability and the validity of findings. The research methodology is designed to provide a comprehensive understanding of training activities in organizations, using multiple techniques to strengthen and confirm results.This research paper by Khairul Baharein Mohd Noor from Universiti Industri Selangor, Malaysia, reviews the literature on case studies as a strategic qualitative research methodology.
