A new and largely ignored set of risks are threatening our organizations. The effects of today’s exploding data volumes have gone overlooked by most business leaders. They may be forgiven for this oversight. Previous leaders did not expect their organizations to cope with data levels growing this fast. Such a data deluge never previously existed. We all need to pay close attention because the data deluge is not only set to continue but to rapidly accelerate, with important consequences for organizations whose behavior is stuck in the pre-Databerg Age. The Databerg concept helps explain how we have got here. Databergs are caused by adding enormous ‘Dark Data’ volumes to poorly understood corporate data. They conceal a threat ‘below the waterline’ that adds significant levels of risk and cost to organizations, and this risk is rising.
