and goals for improvement. NGSP and CAP have been actively tightening
standards in an effort to improve method performance. Have methods improved

in the laboratory (see POC devices, EQC options, and emerging CLSI
standards) . So how do we balance the strengths and weaknesses of Risk
Management? By tapping the strength of another quality management technique:
