Abstract
A method for analyzing test results. The method includes selecting a first subset of tests from a plurality of tests. Test results are gathered from the plurality of tests in real-time. A first statistical analysis is performed on test results from the first subset of tests. At least one process control rule is initiated as determined by results of the first statistical analysis performed on the test results from the first subset of tests.
Claims20
A method for analyzing test results, the method comprising:
- selecting a first subset of tests of interest from a plurality of tests;
- obtaining test results from the plurality of tests;
- performing a statistical analysis on test results from the first subset of tests;
- initiating at least one process control rule as determined by results of the first statistical analysis performed on the test results from the first subset of tests.
A computer-readable medium having computer-readable program code embodied therein for causing a computer system to perform a method for analyzing test results, the method comprising:
- selecting a first subset of tests from a plurality of tests;
- obtaining test results from the plurality of tests;
- performing a first statistical analysis on test results from the first subset of tests;
- initiating at least one process control rule as determined by results of the first statistical analysis performed on the test results from the first subset of tests.
An apparatus for analyzing test results, the apparatus comprising:
- a measured value monitor operable to receive test results from a plurality of tests;
- an adaptive value capture module operable to select a first subset of tests from the plurality of performed tests, wherein the measured value monitor is further operable to gather test results from the first subset of tests and perform a first statistical analysis on the gathered test results from the first subset of tests;
- and
- a statistical process control module operable to initiate at least one process control rule as determined by results of the first statistical analysis performed on the gathered test results from the first subset of tests.
