As Director of Operational Test and Evaluation from 2001 to 2005, Ernest Seglie helped me to make a number of important changes to how operational and developmental testing functioned and the role that statistical methods played. One problem that we addressed is that major defense systems often have a number of innovative components, and testing often begins before all the innovative aspects have been implemented. Rather than have to enter into another acquisition each time a component is updated, we initiated work towards evolutionary acquisition, whereby systems are updated in stages, which has important implications for how each of the tests for each stage are designed and for system evaluation. Further, Ernest Seglie was interested in the higher priority and improved assessment of system reliability, which cannot be well done during operational testing due to the short time duration of such tests. He therefore was interested in using results from developmental test to augment the information collected in operational testing. In addition, Ernest Seglie was concerned with how increasingly complicated software components could be tested as part of developmental and operational testing.
