Engineers fundamentally believe that it’s possible to “get it right”, to create something new that accomplishes its mission and never disappoints. Validators know that, if it is possible, it’s exceedingly unlikely, because they’ve never seen it. Validators learn that if humans are involved, then human error is present. (And sometimes tool errors, manufacturing errors, user errors, and validation errors, possibly all at the same time.) Design engineers would do well to consider the validation attitude while creating their designs.
In this talk I will discuss the impacts and origins of design errors and validation mistakes, and talk about the best way forward.
