I still prefer the focus on complete data as Big is pretty meaningless. Complete means all the structured and unstructured data that can help ensure you have as complete information to make and execute better decisions. Vincent's article shows the breadth of activities that Complete Data will benefit and emphasises SMBs should leverage external data. The data Science points really interesting but I would like more on the other disciplines that must work with data scientists to deliver data driven decisions. Not forgetting business users who are immersed in the world of customers, suppliers and stakeholders to ensure practical outcomes
Healthcare, HR, and law will also benefit from big data, to create customized drugs and reduce healthcare costs, to hire the right candidates by automatically analyzing his tweets, and to better identify criminals (currently, many cases are not pursued because the evidence, based on expert opinion but not on data, is not strong enough for conviction)
