Briefly, from the field perspective, in 2005 the United Nations undertook an important reform process. Essentially, it created the cluster system, which is made up of sectors. You might have a water and sanitation cluster, for instance. They set up these clusters for each and every sector across a response. It pulls together every actor, whether it's the United Nations, an NGO, or the Red Cross movement, so that they work together in a much more coordinated fashion to ensure they address all gaps and any duplication. It's often co-chaired by the government as well as by the United Nations.
What we have learned also over the years is that it's very important to embed civilian and political officers within the DART team to ensure that the full coordination taken from headquarters also reaches deep into the field, and then comes back to headquarters.
