As a UX Contractor for some organizations I get to go between every aspect of the UX UI team. At Cheapcaribbean.com I was given the task of opinion mining through customer comments and then making recommendations on what to do about those concerns. This led through wire framing and A/B tests arranged through 3rd party firms as well.
I was also given the task of a functionality audit top to bottom. This was to contribute on the Wiki so the creative team had some idea of the templates and functionality in place and where to focus their efforts.
