Electronic systems of hardware, software and operating procedures have been motoriously difficult to develop with reliable operating characteristics. These systems handle logical complexities which surpass anything imaginable a few years ago. This complexity leads to new difficulties in developing and testing because of the number of operating modes and test cases that are possible. The present state of art in electronic systems development is to specify and design a system in response to a requirements analysis and then test the system selectively with cases perceived to be typical to those requirements. The result is frequently a system which works well against inputs similar to those tested for, but which is unreliable in unexpected circumstances. In fact, no matter how well the tests are planned, the evidence obtained by selective testing is entirely anecdotal rather than scientific.
