In recent years, Generative Artificial Intelligence (GAI) has evolved significantly and is playing an increasingly important role in supporting business and organisational decision-making. This research aims to explore the role and potential of GAI in this area through a systematic literature review using the PRISMA model. It focuses on the specific tasks in which generative AI can support decision makers and the advantages and disadvantages of using the technology. The research will pay particular attention to the ways in which generative AI can influence human-AI interaction and reduce cognitive biases in the decision-making process. The analysis will explore the experiences and limitations of AI-based decision-making, highlighting the practical benefits and potential limitations of the technology in the corporate environment. The results of this research can contribute to a more effective application of generative AI in decision support and help organisations to optimise their decision-making processes.
