About W3C Groups

Working Groups
Working Groups typically produce deliverables (e.g., standards track technical reports, software, test suites, and reviews of the deliverables of other groups).
Interest Groups
The primary goal of an Interest Group is to bring together people who wish to evaluate potential Web technologies and policies. An Interest Group is a forum for the exchange of ideas.
Coordination Groups
A Coordination Group manages dependencies and facilitates communication with other groups, within or outside of W3C.
Incubator Groups
Incubator Groups foster rapid development, on a time scale of a year or less, of new Web-related concepts. Target concepts include innovative ideas for specifications, guidelines, and applications that are not (or not yet) clear candidates for development and more thorough scrutiny under the current W3C Recommendation Track.

In addition to these groups, W3C has chartered two permanent groups:

Technical Architecture Group (TAG)
W3C created the TAG to document and build consensus around principles of Web architecture and to interpret and clarify these principles when necessary. The TAG also helps to resolve issues involving general Web architecture brought to the TAG, and helps coordinate cross-technology architecture developments inside and outside W3C. Some TAG Participants are elected by by the W3C Members, others are appointed by the W3C Director.
Advisory Board (AB)
The Advisory Board provides ongoing guidance to the Team on issues of strategy, management, legal matters, process, and conflict resolution. The Advisory Board also serves the Members by tracking issues raised between Advisory Committee meetings, soliciting Member comments on such issues, and proposing actions to resolve these issues. The Advisory Board manages the evolution of the Process Document. AB Participants are elected by the W3C Members.
