International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The challenge being faced today in the Department of Defense is to find ways to improve the systems acquisition process. One area needing improvement is to eliminate surprises in unexpected test data which add cost and time to developing the system. This amounts to eliminating errors in all phases of a system’s lifecycle. In a perfect world, the ideal systems acquisition process would result in a perfect system. Flawless testing of a perfect system would result in predicted test results 100% of the time. However, such close fidelity between predicted behavior and real behavior has never occurred. Until this ideal level of boredom in testing occurs, testing will remain a critical part of the acquisition process. Given the indispensability of testing, the goal to reduce the cost of flight tests is well worth pursuing. Reducing test cost equates to reducing open air test hours, our most costly budget item. It also means planning, implementing and controlling test cycles more efficiently. We are working on methods to set up test missions faster, and analyze, evaluate, and report on the test data more quickly, including unexpected results. This paper explores the moving focus concept, one method that shows promise in our pursuit of the goal of reducing test costs. The moving focus concept permits testers to change the data they collect and view during a test, interactively, in real-time. This allows testers who are receiving unexpected test results to change measurement subsets and explore the problem or pursue other test scenarios.
