Which of the following is a feature that allows technicians to receive notifications about their service work orders?

The feature that allows technicians to receive notifications about their service work orders is indeed through push notifications in the mobile app. This method is effective because it provides real-time alerts directly to the technician's mobile device, ensuring that they receive immediate updates on any changes or important information regarding their service assignments.

Push notifications are designed to capture the attention of the user quickly, which is critical in a service environment where timely communication can impact the efficiency of operations and customer satisfaction. This keeps technicians informed and enables them to respond swiftly to their tasks.

Other options, while useful in certain contexts, do not match the immediacy and direct user engagement provided by push notifications. Personal alerts via email can be delayed and are dependent on the technician checking their inbox; daily summary reports sent via SMS may lack real-time relevance since they provide information that may no longer be actionable by the time it is received; scheduled alerts through calendar invites are useful for planning but do not serve the purpose of immediate, situational updates needed for service work.
