<P>PROBLEM TO BE SOLVED: To easily get a systematic problem. <P>SOLUTION: The systematic problem is retrieved from a looking-back storage part, using a conditional expression for retrieving information, based on the frequency of the problems stored in the looking-back storage part, the frequency of trial improvement measures correlated with the problems stored in the looking-back storage part, and one or a plurality of pieces of information indicating whether a storage improvement measure is stored in the looking-back storage part or not, as a conditional expression indicating a condition for extracting the systematic problem, and a retried result is output to a prescribed storage part or a prescribed output part, in the looking-back storage part that is a storage part of storing the problem in an individual project in every input thereof, of storing the trial improvement measure of an improvement measure for the project in every input thereof, of storing the storage improvement measure of the trial improvement measure effective for the project in every input thereof, and of storing the trial improvement measure and the storage improvement measure while correlated each other, as to the plurality of projects. <P>COPYRIGHT: (C)2009,JPO&INPIT |
