In product development there’s a hard-and-fast rule that has been proven over and over again. I talked about this earlier: 80 percent of the value is in 20 percent of the features. Think about that for a moment. In anything that you buy, most of the value—most of what people want—is in only a fifth of what has been built. In this company’s case they looked at this huge list of things that could be included in their home automation system, and they knew—they knew—that customers really only wanted 20 percent of them.
