It’s everywhere. Consider the following sce- nario: I’ll put my comments in brackets [ ]. I mentioned an online story last month about the National Aeronautics an d Space Administration’s Orion spacecraft in orbit around the moon, and they wer e confident the mechanical components would perform adequately. However, the y were not confident the software used to control everything the rocket does was u p to the task. Shortly after it reached orbit, the spacecraft, which had no astronauts onboard , ran into trouble because the flight computers were 11 hours off. [I cannot overem - phasize how critically important this is. Almost everything a computer does is refer - enced to time.] This caused the spacecraft to lose its navigational reference [it didn’t kno w where it was, so it didn’t know where it should be, either] which burned additiona l fuel, which in turn, forced the operators to call off the mission early [there are n o fueling stations in outer space at this time]. Boeing was able to diagnose the problem and send up a software fix whic h managed to bring the spacecraft down safely. Later evaluation [often called a “Postmortem” and for good reason] found both the software itself and the softwar e testing were deeply flawed [Duh!]. Boeing also revealed they did not use the actua l hardware for testing, but used instead an “emulator” which is an equipment “simu - lator” that is supposed to simulate the real-world conditions they are trying to test . However, this emulator had the wrong values programmed into it [which literall y transformed this spaceship into a space boat anchor]. There is no substitute for hands-on testing. If you cannot get hands-on testing, as would be the case here, you find the next best thing. You first test all of the components individually, and then test them as a unit. This is not a new concept and has been used successfully for many years. Henry Royce, the “Royce” of the Rolls-Royce automobile manufacturer, was known to abuse new products to determine if they were fit to use in his automobiles. The idea was, if the product could survive the abuse in the lab, it wouldn’t have any problem performing in the real world. When we develop a new product, we will often give them to the customer at no charge, for testing. We make sure they are working well during bench testing, but it’s not enough. If the product has a problem, sooner or later the problem will sur- face. If it performs well in the field, then and only then, will we consider marketing the product. Why do we “give away” mer- chandise? It would seem to be a poor business model, but it isn’t. We give it away because what we learn from customer feedback is valuable information that can be used to improve it and other products long into the future. We never turn down the chance to learn something useful.
