[0002]
[Prior art]
When solving a quality problem of a product etc. that a company manufactures, it is common to carry out in order of problem definition, goal setting, factor analysis / analysis, countermeasure planning / execution, effect confirmation, standardization / management. As a means for analyzing the problematic problems for that purpose, software using various quality control methods is commercially available, and analysis using these methods has become widespread.
[0003]
However, the scope of the survey and analysis, etc. to grasp the problem that has occurred is often determined based on the past experience of the person in charge and the manager, so the necessary survey and analysis work may be missing. However, useless investigations and experiments are performed without accurate investigations, and the problems that have occurred cannot be solved even if the analysis using software is performed.
[0004]
Further, as an example of a quality control system, for example, as shown in “Quality control device” disclosed in Japanese Patent Application Laid-Open No. H06-150098, the quality abnormal items are determined by the number of occurrences and the downtime of the manufacturing device. A system has been disclosed that provides useful data for taking countermeasures by displaying them in descending order.However, work to reduce unnecessary analysis investigations and solve quality problems that have occurred There was no procedure management involved.
