Responsibility and mandates of each Study Group, including study questions, is set out by WTSA. TSAG may review priorities, programmes, and provide guidelines for SGs. Focus Groups Create forum-like entities under ITU-T Study Group, on a well-defined topic, scheduled for completion at a specific short time. Goal: encourage participation of non-members / members of other organizations (forums/consortiums) [Recent examples: FG IdM, FG IPTV, FG NGN etc.] Regional Groups According to WTSA-04 Res.54, regional groups can be established in order to facilitate developing counties participation in ITU-T activities.
