With the growing complexity and interaction of vehicle functionalities, a reliable functional test methodology has become a major concern. In 1995, recognizing the need to develop a quality functional test process, Ford Motor Company started a concentrated effort to define for itself and its suppliers an effective test strategy for functionality verification. The Robust Test Method (RTM) presented in this article is an important component. Ford successfully applied the strategy in an extremely cost-conscious environment that demands high quality and fast test turnaround time. The introduction of robust test methods into the test process translated into a quantum jump in the test quality, allowing the detection of previously undetected faults. When this type of testing was applied to subsystem-level design verification yielded more errors detected than the module and system tests combined, while reducing the test turnaround time by 30%.
