We switched from a system that had just worked organically over several previous projects. Weekly meetings among the leads with the producer and project manager. Each lead would work out the tasks, time limits, and take into consideration other departments deliverables. Inter-departmental communication was also handled by the leads, there was no pairing off, or groups of different disciplines working together, although this did happen when necessary throughout a project.
As for what Agile method we used, I have no idea what specifically the method was called. We were told our team was going to experiment with Agile but keep it very simple. Teams of 2 or 3 were formed for specific tasks from different departments. Weekly time slots allocated, and reviews done at the beginning of the following week.
