We have a big testing group with nearly 50 people (Onshore/offshore). Now since everyone has access to quality center we would like to minimize the risk of test cases deletion etc. So far we have a custom group created on QATester (default one in QC) with limited delete rights. That is the test case can be deleted only if they are the owners. This worked good, but now recently some one moved the test cases from one folder to another folder and there were nearly 2000 test cases that mixed up. How do I prevent users not doing these kinds of activities? Any ideas on how the custom group should be ...Pl share your inputs.
