I enjoyed this article from Max Wessel at SAP talking about how big data is not always the answer, but more specifically that you need the right data. There is a lot to unpack when you start apply and adding your business processes to this context.

The term “big data” is ubiquitous. With exabytes of information flowing across broadband pipes, companies compete to claim the biggest, most audacious data sets. And businesses of all varieties — old and new, industrial and digital, big and small — are getting into the game.
Masses of social, weather, and government data are being leveraged to predict supply chain outages. Enormous amounts of user data are being harnessed at scale to identify individuals among a sea of website clicks. And companies are even starting to leverage huge quantities of text exchanges to build algorithms capable of having conversations with customers.
