Final answer:
The best way to assist the employee is through a Quick Assist session or a Remote Assistance connection, which allow for real-time observation of the issue without the need for commuting.
Step-by-step explanation:
To provide the best assistance to an employee experiencing issues with an application, the most effective strategies would be to establish a Quick Assist session or establish a Remote Assistance connection. Both options allow you to view the employee's screen and observe the issue first-hand, making it easier to diagnose and resolve. Additionally, these methods are time-efficient and cost-effective compared to driving to the other location, especially considering the productivity losses associated with commuting.
Establishing a Remote Desktop connection to perform the task for the employee could also be a solution, but it does not help the employee learn how to deal with similar issues in the future. Providing additional training could be worthwhile, but it would not immediately resolve the current problem the employee is experiencing.
