You have the flexibility to easily add or delete reports in Sigma, including incorporating new ones without any complications. In terms of users, the advantage lies in the fact that viewers are free and their allocation is unlimited. This has been particularly beneficial for us, as the majority of our users fall into the viewer category. This simplified the process, allowing anyone who simply requires viewing access to be added without any limitations. For users needing additional capabilities, such as making adjustments or creating content, a license purchase is required. However, these users with extended functionalities are limited, and we don't have a substantial number of users falling into this category. We have future plans to expand and continue our utilization of Sigma.
