Big Data at Work:Dispelling the Myths, Uncovering the Opportunities
Thomas H. Davenport
Harvard Business Review Press
2014, 240 pages
Our increasing ability to collect more and more information has popularized the term "big data"--to the point that it has become a catchall that simply means "data." But the words still have meaning. According to Thomas Davenport, "Big data refers to data that is too big to fit on a single server, too unstructured to fit into a row-and column database, or too continuously flowing to fit into a static data warehouse."

Meanwhile, "underachievers" may have had more data, but they did not follow through with analyzing information that would have benefitted them or their customers. Lastly, "data disadvantaged" industries simply did not have the data to analyze, or their data are poorly structured.
DEVELOPING A STRATEGY
After helping readers identify where their organizations may fit on the "big data" continuum, Davenport guides readers into developing a big data strategy. He uses examples from various companies to address some of the common business objectives--reducing costs, saving time, providing new offerings, and supporting internal business decisions--that businesses seek to achieve by using big data.
