Functional research focuses on understanding how different elements within a system or organism work together to perform specific functions. This area of research often involves studying the roles of various components, processes, and interactions in a biological, mechanical, or social system. Functional research often seeks to determine how specific functions are carried out, why they occur, and how they can be optimized or improved. Additionally, functional research can involve developing models to predict outcomes based on the relationships between different elements within a system. Overall, functional research aims to enhance our understanding of complex systems and improve their overall effectiveness and efficiency.
