Are you making daiquiris or blenders?

Many years ago, I was designing a feature for Excel 2003. And the VP of our division of Office, a man named Richard McAniff, didn't like the feature. At one point, he told me:

"Rob, it's like you live in a world where everyone wants really tasty daiquiris. And what you are building is a blender. A blender that, when assembled and used properly, can make great daiquiris. But the problem is, no one wants the blender. They don't want to mess with it, they're too busy for that. What they want. is just the tasty daiquiri."
