Dynamics 365 Field Service has streamlined our field operations with its strong scheduling and resource management features. The mobile app works well for technicians, and integration with other Microsoft tools is seamless. The setup process is a bit complex, and performance can slow down with large datasets, but overall it's a reliable and effective solution for managing field service.

The product seems to lack UI/UX team behind the scenes. It does what you expect it to do, but your users are not going to be happy. It has a very steep learning curve.
