Many of the cataclysmic leadership failures were failures of rationality. The pendulum of leadership development needs to swing back toward the rational: strategy, creativity, foresight, decision-making, and analytics.

The human side of analytics is the biggest challenge to implementing big data.

Ambiguity is not, today, a lack of data, but a deluge of data.

Yesterday’s decision-making strategies are ill-equipped to deal with petabyte information flows.

Use of analytics is accelerating, and that means more data-drivendecision making and fewer hunches. Evidence-based managementcomplements analytics by adding validated cause-and-effect relationshipsbetween policies and effects.
