Inspection planning is a systematic methodological approach within quality management focused on predetermining the necessary parameters, locations, methods, and procedures for evaluating products, processes, or services against specified quality standards. As a research concept, it investigates the optimal design and execution of inspection activities, encompassing the selection of inspection points, definition of inspection criteria, determination of inspection frequency, and allocation of inspection resources, with its significance lying in ensuring effective quality control while optimizing potentially non-value-adding inspection efforts to support overall process efficiency and product reliability.
