A method includes generating first metric data by executing a test suite on a first version of a software model; generating second metric data by executing the test suite on a second version of the software model; generating first and second version principal components that represent the first and second metric data by executing a dimension reduction technique on the first and second metric data; determining at least one control limit based on at least one of the first version principal components; determining a mean value of one of the second version principal components; determining whether the second version of the software model performs within at least one control limit by comparing the mean value to the at least one control limit; and notifying a user of the results of the determining whether the second version of the software model performs within the at least one control limit.
