What work should be done in ITU-T? How should this work be organized? What are the objectives for restructuring the

Study Groups (SGs)? How will SG structure stay relevant?

What is the issue?

TSAG examined the work of all the SGs and work for the future

Identified about 40 “Blocks” of work that should be treated as indivisible units. For example: Block 3A: tariff & accounting principles Block 5A: EMI Block 13B: architecture, interworking and

multi-protocol networks except Ethernet

What work should be done in ITU-T?

How should this work be organized?

Related Blocks are being associated into Related Blocks are being associated into about 15-20 Functional Groupings. For about 15-20 Functional Groupings. For example:example:

Performance FG = Block 12A (all of Performance FG = Block 12A (all of SG12) + Block 13A (WP4/13)SG12) + Block 13A (WP4/13)

EMI = Block 5A (all of SG5)EMI = Block 5A (all of SG5)

ITU-T should have a strong presence in certain areas

Critical areas for future work must include: Next Generation Network (NGN) Security Mobility “E-Everything” Network infrastructure: Optical Transport, IP-

based Networks, Network Management, Signalling, Performance, EMC, Architecture, Interoperability, etc.

BUT – to make it interesting

Two approaches: Change for change sake Two approaches: Change for change sake vs. If it ain’t broke, don’t fix itvs. If it ain’t broke, don’t fix it

Balance between: massive consolidation Balance between: massive consolidation into a few large Study Groups vs. Study into a few large Study Groups vs. Study Groups based on specific topics and Groups based on specific topics and expertiseexpertise

Considerations Some consolidation of work will helpSome consolidation of work will help

Avoid divergent solutionsAvoid divergent solutions Share time of experts among study itemsShare time of experts among study items Reduce need for liaisonsReduce need for liaisons

Too much consolidation of work will hurtToo much consolidation of work will hurt Less time per study item during meetingLess time per study item during meeting Parallel meetings cannot be covered by expertsParallel meetings cannot be covered by experts External liaison relationships become less clearExternal liaison relationships become less clear

Consequences...orWhy do we care?

Make ITU-T THE most attractive place to Make ITU-T THE most attractive place to do international standardsdo international standards

Make best use of experts’ time and Make best use of experts’ time and resourcesresources

Avoid duplication and overlap of workAvoid duplication and overlap of work Lower costs to membership and to ITULower costs to membership and to ITU A bad structure will slow down or stop A bad structure will slow down or stop

Maintaining Future Relevance

TSAG is responsible to review progress of TSAG is responsible to review progress of the work programme, the allocation of work the work programme, the allocation of work among ITU-T SGs and between ITU-T and among ITU-T SGs and between ITU-T and ITU-RITU-R

WTSA Resolution 22 gives TSAG authority WTSA Resolution 22 gives TSAG authority to change study group structure between to change study group structure between WTSAs and to create groups with short life-WTSAs and to create groups with short life-timestimes
