For example, using the information-gain function may yield better results than using the phi function. The phi function is known as a measure of “goodness” of a candidate split at a node in the decision tree. The information gain function is known as a measure of the “reduction in entropy”. In the following, we will build two decision ...
The above example highlights the power of the influence diagram in representing an extremely important concept in decision analysis known as the value of information.

Upon hearing the sounds, the townspeople rushed into the streets. They all stood in silence and awaited the news. She drove to the movies.
The use of such argument analysis for thinking through issues has been called "reflective argumentation". [17] An argument map, unlike a decision tree, does not tell how to make a decision, but the process of choosing a coherent position (or reflective equilibrium) based on the structure of an argument map can be represented as a decision tree ...

Decision table is the term used for a Control table or State-transition table in the field of Business process modeling; they are usually formatted as the transpose of the way they are formatted in Software engineering.
