Some decisions in IPPOG are being taken by different committees or after consultation with advisory boards. These bodies serve for guidance and advice to the Coordination team, Collaboration board or Collaboration as a whole. These groups are based on standing or recurrent need of IPPOG Collaboration for their input. Today IPPOG has an IPPOG Finance and Audit Advisory Board (IFAAB), Speakers and Publications Committee (SPC) and Candidate Selection Committee (CSC).
