Definition of 'Decision Tree Model'

Definition: Decision tree analysis involves making a tree-shaped diagram to chart out a course of action or a statistical probability analysis. It is used to break down complex problems or branches. Each branch of the decision tree could be a possible outcome. 

Description: The tree structure in the decision model helps in drawing a conclusion for any problem which is more complex in nature. The model is used not just in corporate finance, but in philosophy, economic forecasting as well. 

Under the decision tree model, an individual has to come to a conclusion about investing in a particular project or not. The management often use these models because they lay out the information in a graphical way with possible probabilities attached to the final outcome. 

Let's understand how the whole framework is laid out. Start with your decision by putting it in a small square on the left-hand side of the page and then draw conclusions towards the right-hand side. Draw a line for each possible option and the decision is to be written in a square. 

However, if you are not sure, draw a circle. Circles are described as uncertainties. The review of each circle is very important and a percentage is given to each outcome which should add up to 100 per cent. 

The evaluation of the outcome is very important to make a decision. Assign estimated numeric value for each outcome which will help you in taking the right decision. 

The benefit of a decision tree is that it lists out all the possible outcomes and the revenue or loss attached to each. Information available can then be used by the management of the company to make an informative decision about the project or the investment they are planning to make.
