In practical terms, this means that you need to have a good understanding of the data resources you have access to as well as a clear plan for the ways you want to use it to grow your business. It's not how much data you have - despite the buzz about big data - but rather the quality of this data, how quickly you can access it and what you do with it.
Instead of trying to tame the gushing well of big data, rather think about what your business objectives are and which pieces of data will help you to meet them.
