The Leadership of PDCA

PDCA is managed by a Board of Directors, drawn from the membership, who volunteer to serve the organization without compensation. The Board of Directors numbers between fifteen (15) and twenty-one (21) and meets at least quarterly. The Board of Directors adopts PDCA policies, guides programs, appoints Committees, leads PDCA activities, sets member dues, approves the annual budget, and secures and monitors the organization's finances.
