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

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.

Consider how to address the impractical assumptions we made in order to meet the validity and agreement properties for the reliable multicast protocol based on IP multicast. Hint: add a rule for deleting retained messages when they have been delivered everywhere, and consider adding a dummy ‘heartbeat’ message, which is never delivered to the application, but which the protocol sends if the application has no message to send.
