In the field of human cognition, thinking consists of problem-solving and decision-making. In cognitive thinking, top-down processing is an approach used by experts that enables them to solve problems and make decisions efficiently. This paper attempts to apply cognitive top-down thinking process to the concept evaluation of systems and their components. In the top-down concept evaluation approach, engineers first evaluate system concepts. Once a system concept is selected, engineers then identify system components (modules) that they can design independently for the chosen system concept. Engineers generate concepts for system modules and select one concept for each module. The objective of this paper is first to identify characteristics needed for a holistic and structured top-down concept evaluation methodology for a system and its components, and second to propose a research roadmap for establishing the proposed framework.
