Patent ID: 8751436

Claim:
A method, comprising: receiving transaction information from a database; calculating a forecast based on the transaction information, the forecast predicting the future value of a metric; calculating an upper control limit for the metric based on the transaction information; calculating a lower control limit for the metric based on the transaction information; computing the latest actual value of the metric; and calculating a normalized quality score for the metric based on the latest actual value of the metric, the forecast, the upper control limit, and the lower control limit, wherein calculating the normalized quality score for the metric includes: determining a first difference by calculating a difference between the latest actual value of the metric and the forecast; if the latest actual value of the metric is closer to the upper control limit than the lower control limit, determining a second difference by calculating a difference between the forecast and the upper control limit; if the latest actual value of the metric is not closer to the upper control limit than the lower control limit, determining the second difference by calculating a difference between the forecast and the lower control limit; and dividing the first difference by the second difference to obtain the normalized quality score.
