Which of the following tasks is part of the opening procedure for the optical department?

In the opening procedure for the optical department, preparing a UPS shipping slip is a relevant task because it involves logistics necessary for the day's operations. This task ensures that any products or orders that need to be sent out are properly prepared and documented right from the start of the day. Efficient handling of shipping processes is crucial for maintaining the workflow of the optical department and ensuring that customer orders are fulfilled in a timely manner.

While updating customer records, calculating staff commissions, and resolving customer complaints are important tasks, they typically fall under different categories of daily operations or specific employee responsibilities rather than the initial opening procedures. The opening procedures are primarily focused on setting up the department for the day’s workflow, which is why preparing shipping documents is more directly aligned with this task.
