Decent tool, needs additional integration with automation tool
What is most valuable?
Pretty flexible, able to handle different approaches to testing and software lifecycle
What needs improvement?
Not fully integrated with their automation test tool.
What other advice do I have?
From a testing standpoint, ignoring license and cost issues, it's not a bad product. You can use it to organize releases, maintain test cases, and provide management with some decent tools. My concern is with Automation integration. While requirement tracking works fine if you have one automated script per requirement, once you create scripts that cover multiple requirements, any failure in the script updates all requirements as failed instead of giving you the option of only failing those requirements that individually failed. I have an open ticket with HP about this. I was looking at OPA, but couldn't find a viable solution. Other than that, I think QC is pretty decent.

This tool is very useful because it offers visibility and in depth statistics into customer service. It makes sure that no transaction data is lost during the entire transaction process. I find it easy manageable for an efficient user.
