After logical validation checks, the analyst calculates all metric values for which data elements are present and conducts statistical validation on the resulting metric values. APQC employs the Interquartile Range (IQR) method to establish upper and lower bounds to indicate a range of acceptable values. Metric values that fall outside of the established range are flagged for further investigation by the analyst. The analyst may leverage multiple peer groups for comparison in determination of the significance of any outlier against peers with similar industry, size, and regional characteristics. All data elements are then identified as potential outlier factors in statistical outlier metric values. The analyst makes a determination as to the outlier factor’s comparative nature to data elements unlikely to result in statistical outlier metric values.
