Why would a manager prefer a decision tree instead of a decision table?

What will be an ideal response?

Decision trees and decision tables provide the same results, but in different forms. As the chapter points out, a decision tree is a graphical representation of the same conditions, actions, and rules found in a decision table. Decision trees show the logic structure in a horizontal form that resembles a tree with the roots at the left and the branches to the right.
Like flowcharts, decision trees are useful ways to present the system to management. In many situations, a graphic is the most effective means of communication. Like a decision table, a decision tree illustrates the action to be taken based on certain conditions, but presents it graphically.
Whether to use a decision table or a decision tree often is a matter of personal preference. A decision table might be a better way to handle complex combinations of conditions. On the other hand, a decision tree is an effective way to describe a relatively simple process.
