Which practice is likely to enhance the accuracy of mail delivery?

Regular quality control checks are essential for enhancing the accuracy of mail delivery because they involve systematic evaluation of the mail processing system and addressing inconsistencies or errors promptly. By conducting these checks, postal services can identify issues such as mislabeling, incorrect sorting, or other operational mistakes that could lead to delayed or lost mail. Quality control ensures that procedures are followed and that the accuracy of data is maintained throughout the sorting and delivery process. This attention to detail contributes directly to the reliability and precision needed for effective mail delivery.

In contrast, the other practices may not directly improve accuracy. Frequent breaks could lead to interruptions in workflow and might not impact overall accuracy. High-speed processing techniques may improve efficiency but could also increase the likelihood of errors if not carefully managed. Mandatory overtime might push workers beyond their optimal performance levels, potentially leading to fatigue and mistakes, which could negatively impact the accuracy of mail delivery.
