Working as an Interface Designer for Transact Ltd, one of the projects we had in the Business Development department was the Message Me Up Directory. The concept cannot be fully explained due to contract clauses, but basically involved creating an interface for a system similar to that of the Yellow Pages and tying in premium rate messaging services such as shout boxes, web cams and SMS messaging. Usability and User Experience was key to the products success and were my responsibility.
This was a particularly difficult project as the specification was minimal and constantly changing. However this gave me valuable experience in creating layouts that were easily adapted and reconfigured to show project managers a range of possible solutions.
