For a few months I've been working with RWD's uPerform single-sourcing tool. It seems to have a lot of quirks. As a TC I understand tools have quirks; however, this is slowing us down substantially. When I ask the contractor representing uPeform, he doesn't give answers. He avoids all technical questions, such as how does the tranform file work, can we modify the xml in the file or in the transform file, etc. It seems very unprofessional to not share this type of information. I've never, in 13 years, had a vendor insist on keeping all of the technical information a secret.
