The successful implementation of any Dynamics 365 CE project depends on how much the end user knows about the new system. End user training is one of the keys to the successful implementation of Dynamics 365 CE. End user training makes users more comfortable when using Dynamics 365 CE in production. The more they use Dynamics 365 CE for their day-to-day activities, the more the Dynamics 365 CE implementation will be considered successful. The most common reason for Dynamics 365 CE implementation failure is not using the Dynamics 365 CE application for day-to-day activities, and this could be for many reasons, such as lack of proper training, the slowness of the application, or performance issues. We'll talk about user training in more detail the next section.
