 ==== Definition ====
-A decision making tree is essentially a diagram that represents, in a specially organized way, the decisions, the main external or other events that introduce uncertainty, as well as possible outcomes of all those decisions and events.
+A decision making tree is essentially a diagram that represents, in a specially organized way, the decisions, the main external or other events that introduce uncertainty, as well as possible outcomes of all those decisions and events [1].
 **Components of a decision tree**
   - Decision node: a square node; represents decisions you can make
   - Chance (uncertainty) node: a circle node; shows the occurrence of events over which the decision maker has no direct control
-  - Consequences (outcomes: utilities or costs

   * Clear lay out of the problem so that all options can be challenged
@@ Redak 28: / Redak 28: @@
   * Help us to make the best decisions on the basis of existing information and best guesses
 ==== Disadvantages ====
+Some of the disadvantaged of using decision tress for decision making and planning are the following [3]:
+  * Even a small change in input data can at times, cause large changes in the tree
+  * Decisions contained in the decision tree are based on expectations, and irrational expectations can lead to flaws and errors in the decision tree
+  * Large decision trees can be unwieldy and complex to us
+===== Applications =====
+Decision tress are used in the field of operational research, a discipline that deals with the application of advanced analytical methods to help make better decisions. Some examples of the fields where it is used:
+  * business and economics; project management
+  * health economics
+  * public health
