A recent survey on how organization's active data is growing on a year on year basis, looked at two distinct groups:
• Companies experiencing data growth exceeding 50% annually.
• Companies experiencing data growth of 10% or less annually.
So what did the survey reveal?
For starters, companies experiencing rapid data growth were more likely to uncover business opportunities and drive growth. These companies were better able to leverage a wide variety of data types that are both structured and unstructured. And, in comparison to companies with lower rates of data growth, rapid data growth companies:
• 64% more likely to have an executive champion for their Big Data initiatives.
• 68% more likely to have the ability to discover and classify all relevant business data as it arrives.
• 4.3 times more likely to have defined a chief data manager role.
All evidences points to the conclusion that there cannot be a case for excess data. When it comes to data – the more the better.
