Les failles de Big Data

Après des années à lutter contre les approches BI purement techniques et sans valeur, Big Data essaie de nous refaire le coup de baguette magique. Heureusement, il semble que la communauté et les journalistes soient désormais suffisamment échaudés pour ne pas laisser passer l’embrouille…

EDIT : Malheureusement, le blog de Jonathan Mac Donald n’est plus en ligne. Heureusement, j’avais gardé les quelques points les plus saillants, alors je me permets de les recopier ci-dessous :

• Big Data Prediction 1: The financial forecasts for the promise of big data will be wide off the mark, causing a tidal wave of shock amongst companies that are neck deep in the totally unrealistic advice they’ve bought in to
• Big Data Prediction 2: Major expenditure will continue to happen despite targets not being hit, directors will be ousted, profit warnings will be common and eventually even the largest of company fortunes will plummet
• Big Data Prediction 3: The very same people who extolled the virtues of big data will be retrospective experts in what went wrong and try desperately to come up with a new insight that covers over the cracks of what I’d generously term as malpractice
• Big Data Prediction 4: Acquisitions made on the back of the big data promise will eventually be questioned for financial wrong-doing. Values will be written down and scandal will repeatedly hit the headlines, with analysts and commentators blaming accounting errors
• Big Data Prediction 5: Then, the next hype cycle item will capture the imagination and boom, as we went from thinking it was all about digital to all about mobile, we’ll go from all about big data to all about <insert next wave here>
