“How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?” says Sherlock Holmes to Dr. Watson in Sir Arthur Conan-Doyle’s “The Sign of the Four” (and two other books in the series). Many problem solvers have applied the maxim to separate the signal from the noise, finding the real cause. I believe that the maxim creates a real struggle for those under the gun to find the culprit causes. This is one maxim that lots of folks at Toyota are stressed over.
