The paper reports the results of a sensitivity analysis of a state variable model of the Software Test Process (STP). Given a state model of the STP, a sensitivity matrix is calculated using tensor algebra. The sensitivity matrix allows computation of output variations to small perturbations in the model parameters. The results confirm that the model behaves in a manner very similar to what one might expect from a software test process. Results of this analysis also suggest changes and enhancements in the model to improve its accuracy in predicting the behavior of the Software Test Process.
