At first, the logic behind this sounds reasonable: If you change this data element from optional to required, you essentially duplicate error processing that occurs elsewhere in the system.

Prior to a major system error, the impact of the risk of an unintentional user error would be ranked low because of the user's excellent records of entering accurate data.

在发生较大的系统错误前，由于用户在数据正确输入数据方面有良好的记录，因此会认为非故意用户错误的风险影响很低。
