Final answer:
Appian recommends having two essential user groups: Administrators and Designers. Administrators handle overall system management, while Designers manage the creation and modification of applications.
Step-by-step explanation:
Appian, a leader in low-code automation for enterprise businesses, recommends at a minimum having at least two user groups for the effective management and security of applications. These two groups are the Administrators and Designers. The Administrators group is responsible for overseeing the entire application platform, managing user access, and ensuring the security and proper functioning of the system.
The Designers group, on the other hand, is tasked with creating and modifying the applications within Appian. It's critical for maintaining a clear separation of duties and ensuring that the system development is controlled and streamlined.
