Working Group Transition

Since 2015, CCIH Working Groups helped chart our technical directions, organized webinars and forums, identified conference topics and speakers, and guided CCIH initiatives.

In order to enhance our ability to adapt and address emerging issues, the CCIH Board approved a staff recommendation to restructure the Working Groups and sunset them in their current form when their Charters end in September 2023. CCIH will launch a new structure of time-limited Task Forces after September and the current Working Group Co-Chairs will transition to Technical Advisors for CCIH in their areas of expertise.
