The Inter-Sector Coordination Group (ISCG) on issues of mutual interest, which is composed by representatives of all three advisory groups, works to identify subjects common to the three Sectors and mechanisms to enhance cooperation and collaboration in all Sectors on matters of mutual interest, in order to avoid duplication of effort and optimize the use of resources of the Union. It should consider current and new activities and their distribution among ITU-R, ITU-T and ITU-D for approval by the ITU Member States in accordance with the procedures for approval of new and revised Questions. It will also consider the reports by the three Directors and the Inter-Sector Task Force (ISC-TF) on options for improving cooperation at the secretariat level to ensure that close coordination is maximized.
It was originally set up by WTDC-14 through its Resolution 59, which was subsequently revised by WTDC-17. Its Terms of Reference are approved by the three advisory groups.
