It's extremely flexible. Configuring items is straightforward and doesn't require involving the supplier each time. We find the requirement management, test management, documentation, and dashboards very effective.

The aspects related to requirements, testing, changes, tasks, and agile methodology are excellent, which is why we've been using it for a long time.
