The goal of the study was to thoroughly examine the organizational change management and leadership paradigms utilized in various industries. There are various leadership models that can be applied in various situations and change models that are used in various organizations, but there is no evidence of the effectiveness of these models when it comes to managing organizational change, and they aren't discussed as a group in a systematic way either. A research topic that has been highlighted by the studies is to present and examine the leadership models that are most frequently utilized in organizational change management. The past literature on empirical and theoretical topics is compiled via a systematic review. An analysis of the content that is qualitative and descriptive was planned. Scopus, Web of Science, Taylor & Francis, Google Scholar, Emerald, and PubMed search results were for research. The following leadership theories were examined: the Great-Man Theory, the Trait Theory, the Behavioural Theories, the Contingency Theories, the Situational Leadership Theory, the Path-Goal Theory, the Leader Participation Model, the Leader-Member Exchange Theory, the Transformational Theory, the Transactional Theory, the Authentic Leadership theory, the Ethical Leadership theory, and the Servant Leadership theory. Various change management models were also examined, including ADKAR, Kurt Lewin's Change Model the majority of researchers worked on separately examining leadership models and change management in various businesses, but they mostly focused on transformational leadership combined with change management strategies that are helpful in organizational transition. The findings of this study support the widespread use of transformational leadership styles in businesses that were undergoing change. Therefore, it is advised that rather than generalizing the theories, future scholars conduct study by filling up these gaps and concentrating on geographical areas where it is possible to apply leadership models to certain sectors.

We review Sharan B. Merriam and Elizabeth J. Tisdell’s 2016 book, Qualitative Research: A Guide to Design and Implementation and then compare it to three other introductory to qualitative research texts. We found the Merriam and Tisdell book to be useful for both novice and more experienced researchers. The two authors are highly experienced in qualitative research and their book may provide an opportunity to improve our understanding of qualitative research design and implementation when compared to other different qualitative books.
