Most companies only use 5 to 10 percent of the data they collect. So estimates Beatriz Sanz Sai, a 20-year veteran in advanced analytics and the head of Ernst and Young’s global data and analytics practice. While it’s impossible to validate such a claim, the fact is many organizations are gathering lots of data but analyzing little of it.
Legacy database management systems shoulder much of the blame for this. They hog time and resources for the sake of storing, managing, and preparing data and thus impede analytics.
