BMW's Ode to Joy is another example of the One Word Brief Based on an Emotion. In the 1980s we planners tried to focus creative work more single-mindedly by reducing brands to 'essences' and reducing creative briefs to single-minded propositions. The idea was that you would get more cut-through if you tried to say one thing effectively rather than communicate a range of benefits. Someone told me at the time that BMW had been reduced to Cold Precise Perfect, which I thought was rather good. And was clearly the inhuman opposite of Joy.
In the Noughties planners have gone too far. One word is not enough, even if your name is Saatchi (we like this take on that venture). Particularly if it is a bland and blancmange-y word like Joy rather than an interesting and edgy word like Killer (our brand essence at the time for a household bleach). I can see why one bland word goes down a storm at the global sales conference. But really it's an abdication of responsibility. It can lead anywhere from gurning vignettes to gorillas.
And a brief that can lead anywhere is really no brief at all.
