J. L. CAWLEY, Northwest Analytical, Inc., 519 S.W. Park Ave., Portland, OR 97205 HAACP violations are characterized by exceeding critical limits at a Control Point. Often, monitoring CCP values is treated as a go/no-go attribute. It has been demonstrated that using SPC to monitor the underlying process and guarantee a stable, highly capable process is the most effective method to avoid CCP violations. Preventative maintenance programs are designed to avoid process destabilization by scheduling maintenance ahead of expected failure. Such schedules are conservative, and can result in excessive maintenance episodes. By using SPC methods to monitor the process, one can move to an event driven preventative maintenance operation and achieve the same process stability at less cost and downtime.
