Data is observational. What do people actually do? Wal-Mart uses data to decide if an end cap is working. Google Adwords advertisers use data to decide which copy delivers clicks and sales. The library can use data to decide which books to buy (and not to buy). Paco Underhill uses data to turbo charge retail. Data is powerful, overlooked and sometimes mistaken for boring. You don't have to understand the why, you merely need to know the what.
STORIES define everything you say and do. The product has a myth, the service has a legend. Marketing applies to every person, every job, every service and every organization. That's because all we can work with as humans is stories. I want to argue that data and stories are the two key building blocks of marketing--the other three are built on these two.
