On Big Data and Data Science: Is This Hype?

Daniel, Thank you for recognizing Gartner's/my original 3Vs from over 12yrs ago. For future reference, you and your readers might like to see the my 2001 piece first positing them:Three Dimensional Data Challenges. However, I'm confused why you suggest there should be objective indicators for each dimension. Just to keep people from "abusing" the "big data" term? Who really cares? It's both a relative and moving target: I.e. one organization's big data is another organization's not-so-big data. And next year, this year's big data may not seem so big. Gartner's updated definition recognizes this in suggesting that you have big data when "...new innovative forms of processing" are required.  That's all that really matters--when your current infrastructure components can no longer handle a jump in your data's volume, velocity and/or variety. Otherwise, I totally agree that big data has just entered it's golden run. Cheers, Doug Laney, VP Research, Gartner, @doug_laney

On How Data Hoarding Is Costing Your Business

Great piece Ephriam! Assessing which information is qualitatively deemed "important" is just the beginning however. Gartner is working with clients to quantify the actual *economic value* of their information assets using models we have developed as part of our infonomics research. We gauge the gap between retention costs, realized value and probable future economic benefits to make well-informed retention, management and usage decisions. Similarly, thought leaders at IBM incl Deidre Paknad are proponents of "defensible disposal" using quantified methods to determine information retention.

On What Really Is Big Data? And Why It Will Change the World

Nice piece. Looking forward to future posts. Great to see the industry adopting Gartner's original "V"s of bigdata, albeit 12+ years since I first posited them (http://blogs.gartner.com/doug-laney/deja-vvvue-others-claiming-gartners-volume-velocity-variety-construct-for-big-data/) 

Note also that Veracity was added by others trying to be clever or avoid the professional courtesy of proper attribution. Unfortunately, Veracity, Value and other recently suggested V's are not definitional characteristics of bigdata. Value is a goal and Veracity unfortunately is inversely related to the actual "bigness" characteristics. Conflating them only confuses people--as Seth Grimes pointed out in his recent piece. 

Cheers, Doug Laney, VP Research, Gartner. @doug_laney

On The Viability of Big Data [INFOGRAPHIC]

Great infographic and data. However, we need to be cautious about attributing new "V"s to Big Data that are not definitional. It just confounds and conflates its meaning. Cool tho to see the industry *finally* adopting Gartner's original "3Vs" framework for Big Data that we introduced over 12 years ago in the piece I wrote on the "3-D Data Management Challenge" (ref: http://goo.gl/wH3qG). Would be great however to receive the professional courtesy of a proper citation. --Doug Laney, VP Research, Gartner, @doug_laney

On Five Factors to Consider for Your Big Data Initiative

Always pleased when people use Gartner's original "V"s from 12 years ago for defining big data, but more pleased when they're both cited and used properly. Here's the piece I authored on "The Three Dimensional Data Challenge" back in 2001 first introducing them: http://goo.gl/wH3qG. The 3Vs (volume, velocity, varity) were meant to be characteristic of Big Data. Other "V"s that people have glommed on, e.g. veracity (actually an inverse attribute of Big Data), value, variability, velociraptor or whatever are *not* definitional and merely confuse matters. They may be important aspects of *all* information (as are the 12 dimensions Gartner later introduced), but should not be used to conflate the definition of Big Data. --Doug Laney, VP Research, Gartner, @doug_laney

On Statistics vs. Data Science vs. BI

Interesting to see your perspective on these similar roles David. At Gartner last year we used a bit of data science (rather than our own ruminations) to settle the debate. We text mined hundreds of job postings for data scientists, statisticians and BI analysts to discover the similarities and differences in what actual companies are looking for in the skills, qualifications and responsibilities of these roles. For my blog on this: http://blogs.gartner.com/doug-laney/defining-and-differentiating-the-role-of-the-data-scientist/. For Gartner clients who want to see the in-depth analysis: http://www.gartner.com/document/1955615 ("Emerging Role of the Data Scientist and the Art of Data Science"). --Doug Laney, VP Research, Gartner, @doug_laney

On Big Data Goes Real-Time

Fun piece!  Great to see IBM and the rest of the industry adopting the "Vs" of Big Data that Gartner originated over a dozen years ago (See: http://goo.gl/wH3qG). Note however that while "veracity" and other V's that people have posited recently are important, we do not believe they are definitional when it comes to Big Data. They apply to all data and are mutually exclusive of Big Data. As clever as additional "V's" are (and as much as it enables vendors to forgo citing Gartner's original research), the level of data's veracity has no bearing whatsoever on whether it is in the realm of Big Data or not.

Note also that Gartner, as part of our original research into what we call "infonomics" (the economics of information), has developed valuation models that enable organizations to quantify the contribution of individual information assets to financial or other goals. (Search Gartner.com for "infonomics" to find related research or visit the Wikipedia page on Infonomics for more resources and articles.)

On Driving Analytic Value From New Data

Great post Bill. Note that the 3Vs as I first defined them over 13 years ago (ref: http://goo.gl/wH3qG) were meant only to define the challenges and opportunities of Big Data. Value is important of course (along with a dozen other dimensions Gartner has identified), but it is not a defining characteristic of Big Data. That is, you can have Big Data but not be generating value from it. "Value" also is a vague, slipery word that's thrown around too casually: enterprise assets that are unutilized have probable value recorded on balance sheets, and deployed assets have realized value recorded in income statements. And "benefits" are often an unfortunate, insufficient proxy for actual value. Notwithstanding the fact that accounting principles *still* do not allow for information assets to be recognized, they meet all the criteria. Recognizing this and information's growing economic importance, I developed and have been teaching information economics (infonomics), including information valuation methods for some years (ref: http://en.wikipedia.org/wiki/Infonomics). Happy to connect on this w you. 

Also, it's great that you point out the importance of "new data". This is one of the fallacies/limitations of Moneyball that people don't realize: new statistics were developed using old measurements. New ways of measuring player performance (e.g. Sportsvision's Field/fx system of capturing 2M datapoints per game) and similarly corporate/individual/process/machine performance are critical.

On Big Data Defined for 2013: A Definition That Can Help in Your Interaction with the IT Community

Great report, but unfortunate that TechAmerica authors failed to cite either Gartner's original "3Vs" framework that I conceived and authored over 12 years ago (ref: http://goo.gl/wH3qG), Gartner's expanded Big Data definition that incorporates use types and recognition of new forms of processing, or Gartner's "Art of the Possible" research note from 2011 -- each which they seemed to posit as their own ideas. Novel ideas may be hard to come by, but professional courtesy shouldn't be. --Doug Laney, VP Research, Gartner, @doug_laney

On The Buzz About Big Data Analytics

Hi, Here is a link to the original 3Vs article from 2001: http://goo.gl/wH3qG.  Yes, TDWI and others use the concept without the professional courtesy of attributing it to Gartner. -Doug

On Big Data Vs. Traditional Business Intelligence

Great piece Kathryn. Monetization is definitely the big win with big data. Cool to see others in the industry finally adopting Gartner's original "3Vs" from 12 years ago. Ref: http://goo.gl/wH3qG. --Doug Laney, VP Research, Gartner, @doug_laney

On Why Big Data and Business Intelligence Are Like One Direction

Thorough piece Lachlan. Enjoyed it. Good to see the "3V's Gartner identified and first published about 12 years ago are finally understood and have been broadly adopted by the industry. For proper attribution, here is the piece I wrote in 2001 first suggesting and defining these three dimensions: http://blogs.gartner.com/doug-laney/deja-vvvue-others-claiming-gartners-volume-velocity-variety-construct-for-big-data/.

Since then, Gartner has identified 12 dimensions of data management challenge and published an updated definition of Big Data that reflects (as you also suggest) the value side of Big Data equation: "Big Data are high-volume, -velocity, and/or variety information assets that require innovative forms of processing for enhanced decision support, business insights, and process optimization."

Gartner has also developed methods for quantifying the economic value of Big Data sources that companies can use to gauge investments and opportunities in information management/analytics/infosec/etc, and a data magnitude index (DMI) that can help in planning and anticipating needs for new infrastructure & architectures.
