JS Foundation Working Groups (WG) are autonomous projects created by the Technical Advisory Committee (TAC). A WG may be appropriate when concerns or needs cross multiple Foundation Projects or Collaboration Boards and the represented Projects wish to coordinate their efforts. WGs may also be formed for Foundation-wide technical initiatives that may or may not directly involve or impact any single project.
Working Groups can be formed at any time but must be ratified by the TAC. Once formed the work defined in the Working Group charter is the responsibility of the Working Group rather than the TAC.
It is important that Working Groups are not formed pre-maturely. Working Groups are not formed to begin a set of tasks but instead are formed once that work is already underway and those involved think it would benefit from being done as an autonomous project. The exception to this rule is Foundation-wide technical initiatives where formation of a Working Group in order to define and organize the work would be desirable.
If the work defined in a Working Group charter is completed, the Working Group should be dissolved and the responsibility for governance absorbed back into the TAC or other appropriate governing body as defined in the Working Group charter. A Working Group can be dissolved either through consensus of the Working Group membership or normal TAC motion and vote.
