The Joint Staff, J8, Vice Director (VDJ-8), is the "gatekeeper" of the JCIDS process. The gatekeeper assigns the JPD, and assigns lead and supporting functional capabilities boards FCBs, and performs an initial review. The gatekeeper initially reviews all proposals, and then designates the Joint Potential Designation, and which Functional Capability Board and Joint Warfighting Capability Assessment Teams will receive the proposal. The Joint Potential Designation is based on input from Joint Forces Command, each of the Joint Warfighting Capability Assessment teams, and other elements of the Joint Staff. The gatekeeper periodically reevaluates the Joint Potential designation throughout the process because changes in the proposed capability may require it to change as well.
