 TSAG is the advisory group of ITUT and its function is mainly to provide oversight on a number of important issues including structure, working methods, finance, operational planning, strategic planning and so on. So the advisory group meets once a year, it meets between the standardization assemblies to provide some continuity in the kinds of decisions that are taken by one assembly as we prepare for the next one. So that's really been our focus over the last four years. Now of course the study groups are very much involved in providing input and information to the advisory group. We rely on contributions from the membership in order to provide us with ideas as to how they would like us to move forward with regard to the way in which the sector adapts to the changing environment. Well since about a year ago we've begun our preparations in a number of important areas. One of them is in the area of work program and study group structure and we've established a rapid tour group in that area. We've also established a rapid tour group on working methods, one on strengthening collaboration between ITUT and other entities including standard development organizations, rapid tour group which was existing on the examination of the operational plan and the strategic plan and at the last meeting we established a new group which is based on a recommendation from the review committee to establish a rapid tour group on standardization strategy. Now that group has not become operational yet but it will be after the WTSA and I think it's extremely important to have this group to provide an overview of the changes in the environment and how ITUT might adapt to those changes.
