Gap analysis is a research method used to evaluate the difference between current and desired states in a particular research area or field. It involves identifying gaps or discrepancies in knowledge, resources, methodologies, or practices, and determining strategies to bridge those gaps. Gap analysis helps researchers identify areas for improvement, prioritize research objectives, and plan future research directions. It is often used in a variety of disciplines, including business, healthcare, education, and environmental science, to inform decision-making and drive innovation.
