Big Data and Management



Big Data and Management

                With the explosion of Big Data, many managers are wondering how they can get in on a piece of the action.  The article says Big Data is important to management because they can measure business performance and make adjustments. You have to be able to measure before you can fix.
                Booksellers in physical stores could always track which books sold and which did not. But with online sales, booksellers are now able to get a better understanding of the customers and their purchasing habits. They can not only track what they bought, but what they looked at, how much they were influenced by page layouts and promotions, and how they were swayed by reviews. Traditional retailers were put out of business because they could not keep up with these new algorithms.  
                This new online retail standard has set the bar high for new online companies.  People expect new digital companies to accomplish things that were unheard of a decade ago.  The article says that these powerful tools can be used for management decisions. “We can make better predictions and smarter decisions. We can target more-effective interventions, and can do so in areas that, so far have been dominated by gut and intuition rather than by data and rigor.”**
                The article separates Big Data and Analytics by highlighting two key differences between the two. Velocity and Volume are the two big differences between Analytics and Big Data.

Volume: As of 2012, about 2.5 exabytes of data are created each day, and that number is doubling every 40 months or so. More data cross the internet every second than were stored in the entire internet just 20 years ago. This gives companies an opportunity to work with many petabyes of data in a single data set—and not just from the internet. For instance, it is estimated that Walmart collects more than 2.5 petabytes of data every hour from its customer transactions. A petabyte is one quadrillion bytes, or the equivalent of about 20 million filing cabinets’ worth of text. An exabyte is 1,000 times that amount, or one billion gigabytes.**

Velocity. For many applications, the speed of data creation is even more important than the volume. Real-time or nearly real-time information makes it possible for a company to be much more agile than its competitors. For instance, our colleague Alex “Sandy” Pentland and his group at the MIT Media Lab used location data from mobile phones to infer how many people were in Macy’s parking lots on Black Friday—the start of the Christmas shopping season in the United States. This made it possible to estimate the retailer’s sales on that critical day even before Macy’s itself had recorded those sales. Rapid insights like that can provide an obvious competitive advantage to Wall Street analysts and Main Street managers. **

  1. I think this is another blog that talking about the big data application in the supply chain. As I said before. Wal-Mart is one of the best companies that use the big data technology. Actually,as we known, except Wal-Mart, Apple and eBay also have some of biggest data warehouses as we have ever seen. In the era of big data become more and more popular and important, many companies have introduced big data technology. Let’s see how the customers use the company’s analytics software. “Teradata’ approach” is a technology to handle big data workloads and make no mistake about the company’s clout. Now the following is how they are using Teradata and at what scale. For Wal-Mart including Sam’s Club, Teradata’s first-ever terabyte-scale database is deployed in1992. And it has been developed a lot during these years. “The analytics efforts have essentially helped Wal-Mart become a massive consignment shop.” said by Derrick Harris. It will tell the suppliers how to optimize the shelf space using the data that given by the supplier. Then through the analysis approach, it helps to determine what to sell, the refill frequency, even whether they need to redesign their packaging to fit more on the shelves. It is very helpful and makes more profit for the Wal-Mart stores. Not only Wal-Mart, Apple and eBay also use this approach to increase the customer experience in order to make more profit.
