According to an improvement support system (100) comprising an input unit (12), a display (11), an arithmetic processing unit (13) and a storage unit (2), the storage unit stores analytical data (21) containing analytical information corresponding to "phenomenon" or "influence" and "cause" or "measures" for each of failure modes previously extracted at a stage of product designing or process designing, and malfunction generation historical data (22, 23) in which malfunction information formed based on the contents of malfunction and related to the failure mode of the analytical information is sequentially accumulated every time the malfunction is detected after the system is started. The arithmetic processing unit (1) has a function of retrieving the analytical data (22 and 23) using the malfunction information as a key and detecting the failure mode correlated with the malfunction. Thus, the number of malfunctions related to the analytical information regarding each failure mode is counted and the total number of malfunctions related to the failure mode is displayed with the contents of the failure mode in the display.
