What should happen is that the designers think positive while the testers think negative AND the testers have the authority to prevent release of whatever it is that's being developed. What happened to NASA was basically as simple as testers (perhaps it would be more accurate to say their managers) thinking positive ("Well, so what if it failed this test? It'll work anyway!). What made it worse was that the chains of command of designers and testers met at far too low a level (i.e. not at the top). Good ol' Larry Mulloy (head of NASA's solid booster division) should never have been able to intercept the test results. But he did. Don Stock
