Shared Job History Notification and Ownership Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing devices face the challenge of preventing the unintended deletion of process execution information shared among multiple users, which can result in other users being unable to access the information.
Innovation Solution
The device notifies users of existing use histories before deleting shared process execution information and allows management users to change ownership or settings to prevent deletion, ensuring that information is not lost if other users have a history with it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a management user deletes process execution information with sharing settings, then the storage space is freed and the deletion instruction is executed, but other users who have used the information cannot access it anymore
Solution Approach 1:
The system performs a preliminary check before deletion to identify if other users have used the process execution information. This advance detection prevents unintended deletion by notifying the management user of the use history before the deletion instruction is executed, allowing them to reconsider or modify their action.
Solution Approach 2:
The system provides feedback to the management user by notifying them when other users have used the process execution information. This feedback mechanism creates a loop where the management user receives information about the impact of their deletion action and can adjust their behavior accordingly, balancing storage needs with data availability requirements.
2Reliability
If the system notifies users before deletion, then data loss is prevented, but the deletion process becomes more complex
Solution Approach 1:
The notification check is performed as a preliminary action before the actual deletion process. This separates the complexity of the notification mechanism from the core deletion function, allowing the deletion process to remain relatively simple while adding a preventive check step that ensures data availability.
3Quantity of substance
If shared process execution information is deleted, then storage capacity is increased, but the information cannot be accessed by previous users
Solution Approach 1:
The system performs a preliminary detection of use history before deletion occurs. This advance action identifies potential information loss risks and notifies the management user, preventing the deletion of information that would be inaccessible to previous users while still allowing deletion of information that can be safely removed.

AI summary
In the present invention, when an instruction has been received to delete shared job history information, from among job history information stored in a job history storage unit 37, that has been set in a shared manner so as to be available to a plurality of users, a controller 35 provides notification that a usage history by another user exists if a usage history by another user other than a managing user of the shared job history information exists.
