The most valuable feature is the way it works, the usability. From the first setup, the user interface is the most beautiful. It's very nice the way you can recover things and make it work. We use the solution’s Test Planning & test Execution Scheduling features, and they are very important. They are easy to work with. We use SAP Solution Manager, and Qualibrate works with it, enabling us to manage all our tests, taking them from Solution Manager directly into Qualibrate. Because everything we do is in SAP Solution Manager, we are now able to do test automatization, combined with Qualibrate. All the defects are available in SAP Solution Manager and all the changes will be in Qualibrate, immediately. From Qualibrate, we see whether tests are good or not. We can create a test-related incident in Solution Manager for those that are not good, and Test Suite in Solution Manager will notify the person who has to rebuild it. That works very nicely.
