How do you create a discipline around making good decisions for business strategy? I've seen "highest paid person" win, I've seen "Most vocal" win, I've seen "5 versus 1" win. The testing advocates I've worked with have an attitude of "I don't know what will work - that's why we're testing". I have not seem much of that attitude from most other individuals/teams involved in decision making -- they have preferred to say "this will work", and get angry when I say, "compared to what? how do you know?" edit - fwiw, I totally agree with understanding the limitations of testing. You have to know what it can be good for. My argument is that it's actually better for long term strategy than most other decision making processes I have experienced, which usually boils down to "gut based".
