I like that Taverna is easy to use and can be customized to suit your needs. It's also very flexible, allowing you to create custom workflows. It takes some time getting used to but once you do, it becomes second nature. One thing I don't like about Taverna is that you cannot have more than one workflow running at a time. This is a big issue when trying to run multiple tests in parallel. I would recommend using Taverna if you want to quickly set up a test management system for your team. We were able to set up our own test management system within minutes.
