Andreas Weigand has a blog post on Eight Rules of Big Data.

Start with the problem, not with the data
Share data to get data
Align interests of all parties
Make it trivially easy for people to contribute, connect, collaborate
Base the equation of your business on customer centric metrics
Decompose the business into its “atoms”
Let people do what people are good at, and computers what computers are good at
Thou shalt not blame technology for barriers of institutions and society

Here is video of Andreas presenting the Eight Rules at Walmart Labs.
