This can be confirmed, so it is wrong. Application, agreement, return, and approval are all operations carried out on the ringi system, and the workflow history records who performed which operation and when, with a timestamp attached. The date and time at which each operation was performed can therefore be read directly from the history.
×Incorrectイ
This can be confirmed, so it is wrong. Both the date and time of the application and the date and time of the final approval are recorded in the history, so taking the difference between them gives the time taken from application to approval. Grasping the lead time up to approval is in fact a typical reason for introducing a ringi system, namely to analyze bottlenecks in the work process.
○ウ
正解The correct answer is ウ, the number of revisions made before the application. Under the specification in the stem, the ringi system (an internal approval-request system) executes processing when the execute button on the application, agreement, return, or approval screen is pressed, and saves the input items and the date and time as history. The stem also states explicitly that information entered before the application is not saved as history. Input before the application is an operation on the system, since a ringi can even be saved temporarily as in (1), but the specification excludes it from the history, so how many times it was revised before the application is not recorded and cannot be confirmed. In contrast, the date and time of each operation (ア), the time taken from application to approval (イ, the difference between the application and approval times), and the number of returns (エ, the count of return entries in the history) can all be obtained from the saved history.
×Incorrectエ
This can be confirmed, so it is wrong. A return is also one of the operations on the system, and each time it is performed one entry is recorded in the history. Counting how many return entries exist for that case therefore tells you how many times a return was performed.
ここがポイント
Per the specification, the history of the ringi system consists of the input items and the date and time at each execution of application, agreement, return, and approval. Because information entered before the application is not saved as history, revisions made before the application are not recorded even though a temporary save is possible.
Because the recorded operation logs include the person who performed the action, the type of operation, and the date and time, secondary information can also be derived from them, such as the difference between timestamps (the time required) or the number of entries of the same kind of operation (the number of returns). This is exactly what underpins the improved efficiency and the visibility of progress that come from making the approval process electronic.
