In my years of managing design processes, this distinction always seems to get lost in the excitement. When I look at a troubled design team, this is the first area that I diagnose. It's what I meant when I said that the engineers and managers have siezed complete control of the industry. The current focus is on features, not benefits. Features are best described in quantifiable performance terms.
Benefits are values.
I'd propose describing the MMC's benefits and then mapping features on to them. So, with your indulgence, I'd like to tell you three or four stories over the next day or so. I'll make every effort to keep them compact. My Family's Learning Curve Kate, my four year old, has been using a Macintosh since well before she could speak. She's learned some spanish, counting, the alphabet and pattern matching.
