I used IBM Rational RequisitePro for two years. We can define the test plan for the business and the teams can follow that. The status for all the phases in the test cycle can be tracked efficiently through the software. One can manage the test cases, review, approve and define the interdependencies between two kinds of test cases. We can estimate the size, complexity and effort required to carry on a test cycle.

The main problem with IBM Rational RequisitePro is the interface not being very friendly.
A lot of companies adopt the software but the employees still follow the traditional way of managing the tet cases.
The software faces problem in getting signed off after a few minutes of inactivity. This should be taken care of.
The software crashes at times and needs an upgrade. Sometimes the application responds very slow which consumes a lot of user time. Possibly a new patch can resolve the issues. Review collected by and hosted on G2.com.
