Since we actually conduct usability tests with our products every week, we have a really good idea what kind of lab solution you need and will propose solutions to you. We will also listen to your needs and adjust our base design accordingly. Tell us what you need. Ovo Studios understands and develops its entire usability lab solution. There are no sub-vendors for subsystems.
Some systems have sub-vendor components that are bolted on.
The guy who sells you the lab might not understand the details of the encoder or how the logging software really works. This impacts the overall usability and functionality of the system as well as the ability for the vendor to service the system for you. I'm as guilty as anyone else when it comes to clinging to my tapes. They reassure me that my test data is there if anyone ever wants to view it again. In reality, I never look at the tapes again because they are not tightly integrated with the notes I took during testing.
