Data, Big Data, Data Science, Analytics, and Visualization are necessary competencies, but they are not sufficient. Without bridging the last mile, these competencies are like heating water to 211 degrees Fahrenheit. Not bad, but not good enough.
What's the extra 1 degree to get the water to really boil and steam? Decision-making!
You have to bridge that very last mile - bringing the result of all the data competencies to help companies decide and solve problems. You have to consider judgment under uncertainty, biases, and heuristics in decision-making.
Without that, it's just a lot of hot air!
