When preparing for the PL-500 Microsoft Power Automate RPA Developer exam, one of the crucial topics to grasp is understanding the fundamental differences and considerations when running desktop flows in attended versus unattended settings. Desktop flows automate repetitive tasks on local machines and applications, critically saving up man-hours and enhancing efficiency.
I. Attended Versus Unattended Desktop Flows
Attended desktop flows are run on the user’s device, requiring interaction or oversight by the user. For instance, the user may need to initiate the flow or provide input during the operation.
On the other hand, unattended desktop flows can run independently without any human intervention. They are typically triggered as per a specific schedule or event and run on a virtual machine or a Windows device locked in the background.
II. Considerations for Running Desktop Flows Attended versus Unattended
1. User Interaction and Supervision:
- Attended: User input or supervision is necessary as the flow is user-initiated and runs on the user’s device.
- Unattended: No user interaction is needed. The flow is service-triggered and independently runs on a virtual machine or locked device.
2. Security and Privacy:
- Attended: User data security is less significant as the user can monitor the flow’s activity.
- Unattended: Security is a top priority as the flow has automated access to perform tasks independently.
3. Execution Time:
- Attended: Execution time is variable and depends on the user’s availability to initiate or oversee the flow.
- Unattended: Execution time is fixed and can be scheduled to guarantee timely task completion.
4. Error Handling:
- Attended: Less worry about error handling as the user is available to monitor and react to any issues.
- Unattended: Robust error handling and recovery strategies are required to manage errors during the autonomous process.
III. Use Case Examples
A practical example for attended flow is customer service scenarios, where a customer service representative interacts with various systems during a customer call. An attended desktop flow can help streamline this process by automating certain tasks like data retrieval or entry while the representative still supervises the overall process.
An unattended desktop flow example could be a daily routine task like producing reports and analytics. This is initiated at a specific scheduled time, runs independently, and typically sends an email report upon completion. In this case, no user intervention is required once the flow is set up.
Understanding these variables between attended and unattended operations is vital for the PL-500 Microsoft Power Automate RPA Developer exam and applying this knowledge effectively in real-world scenarios. Always consider both the technical aspects and organizational needs when determining the best approach.
