This invention relates to a defect countermeasure status management method that visualizes the defect countermeasure status by periodically displaying the defect countermeasure status on a screen.

[Conventional technology]

Conventionally, as a management method for production systems, there were methods to display defect status (for example, Japanese Patent Laid-Open No. 62-39165).
(see publication). In the above method, in the automobile production process,
This method calculates the residence time of defective products in the repair shop and displays identification information on the screen to workers for products that exceed the time limit.

However, this method is used to manage the time taken by workers to correct defects in the assembly process, and simply displays the residence time for defect correction.

[Invention or problem to be solved] By the way, when developing hardware and software at the same time, conventionally, in order to manage the status of defect countermeasures in the actual machine testing process such as testing and inspection, communication is carried out after identifying defective parts. A ticket was issued to isolate the defect, and management materials on the identification of defects and the status of countermeasures were created and distributed to designers in the countermeasures department.

However, with this method, it is not possible to immediately know whether the current defect countermeasure situation is as described.
It was necessary for those involved to contact the defect correction manager each time.

The purpose of the present invention is to solve such conventional problems, and to immediately or periodically notify necessary people such as countermeasure personnel and managers at necessary times such as when detecting or taking countermeasures against defective countermeasures. The purpose of the present invention is to provide a defect countermeasure status management capability and method that can be displayed on the screen and that allows the user to always grasp the latest information on the status of defect detection and countermeasures.

[Means for Solving the Problems] In order to achieve the purpose described above, the defect countermeasure status management method of the present invention includes (a) storing numbers and classifications in the order of the detected defect points in the memory within the defect countermeasure management system; , a defect information management table that stores the subject, importance level, countermeasure department, and countermeasure change status is provided, and the contents of the defect information management table are updated every time a countermeasure is input from the person in charge, and the stored defect countermeasures are updated. A distinctive feature of this system is that the information is displayed immediately or periodically on the display devices of all parties involved, according to the display conditions for each level of importance and countermeasure department. (b) In addition to the defect information management table that stores defect information, the memory also contains a countermeasure days management table that shows the number of work-in-progress days since the defect information was detected, and unmeasured defects that are selected from the defect information management table. A display information management table that extracts the display content and display type for each display destination and terminal address, and a display that determines whether or not to perform a blinking display based on the importance level and number of days in progress in the defect information management table. Another feature is that a blinking determination table is provided.

[Function] In the present invention, an information processing device (defect countermeasure management device) that executes defect countermeasure management registers defect information of extracted defective parts in a defect information management table, and calculates the number of countermeasure days for each registration. and register the number of days in the countermeasure days management table. Next, the defect countermeasure management device extracts unmeasured defects from the defect information management table and registers the display destination terminal address, display content condition code, importance level, and defect countermeasure department in the display information management table. Accordingly, on each screen of the terminal address, the defect contents are divided by importance level, defect countermeasure management, etc. according to the display contents condition code, and displayed on the screen immediately or periodically according to the display type code. Further, in accordance with the display blinking determination, the corresponding defect information is displayed blinking.

As a result, the status of changes in countermeasures for the identified defective locations is registered in the management table and displayed on the screen each time the registered contents are updated, allowing those involved to grasp the countermeasure status for each defective location.
