Gartner’s Analytic Ascendancy Model. A graph with Difficulty as the x-axis and Value as the y-axis. An arrow beginning at the origin moves from lower left to upper right with the word “Information” on the lower right end and “Optimization” at the upper right end. The words” Hindsight”, “Insight”, and “Foresight” progress up and right along the bottom edge of the arrow. Boxes labeled “Descriptive Analytics – What happened”, “Diagnostic Analytics – Why did it happen?”, “Predictive Analytics – What will happen?”, and “Prescriptive Analytics-How can we make it happen?” progress along the arrow’s top side from lower left to upper right. The message is that though the forms of analytics become more difficult as you move up the arrow, the value gained increases.
