Very interesting story.
The tyranny of process .... having a bit of retail exposure I can tell
you there is plenty of process behind all of Walmarts intentions so it
is no accident. They managed to engineer it that way with plenty of
proof.
Coke had a similar story with new Coke somewhere in 80's if memory
served me right. Pepsi was making headway, winning first taste tests
and was reported to be tasting better than Coke and coke's researchers
confirmed this and after a lof research and development new coke was
born a better coke. Indeed the first sip of Pepsi and even New Coke
did taste better... BUT it is not first sip that really counts! The
moral of the story in someway is that by trying measure user behaviour
we learn we can influence people to tell us what they think they want
us to know. The Hawthorne effect. (For those that don't know the
story, in coke's case it caused and uproar from coke fans, new coke
was still born, it turned out to be positive for coke but nearly
became a disaster)
I bet it happens a lot more than people want to admit to, imagine
spending all that money, who is going to tell the boss A we were
stupid? B because we were stupid we wasted even more money?
