Focus Groups are an instrument created by ITU–T to provide an additional working environment for the quick development of standards in specific areas. The procedure in ITU-T Rec. A.7 defines how an "arms-length" entity (called a "Focus Group" in ITU-T parlance) can be created to work with an ITU–T Study Group as a parent body while at the same time maintaining a high degree of independence, in particular concerning working methods, types of outputs, membership, financing, and administration.
Focus Groups generate outputs in well-defined areas within a short-term charter; these products can remain stand-alone Focus Group deliverables (e.g. Technical Specifications or Technical Reports), or may be proposed into the Study Groups for progression into traditional ITU-T products (e.g. Recommendations and Supplements).
Focus Groups can originate from within ITU-T or from an external group. Two examples are the URN Focus Group (endogenous) and the FS-VDSL Focus Group (exogenous). See links below for details and examples.
