Why are decision trees used?
Decision trees are used because they are simple to understand and provide valuable insight into a problem by providing the outcomes, alternatives, and probabilities of various decisions. This makes it easy to evaluate which decision results in the most favorable outcome.
How can businesses select the decision that produces a favorable outcome?
By modeling the various expected outcomes and their probabilities, businesses can then select the decision that produces a favorable outcome.
What happens when there are multiple decisions to be made?
If there are multiple decisions to be made, a business will calculate the expected value for each decision to determine which is most favorable.
What is the purpose of decision analysis?
Going to an even deeper level, the purpose of decision analysis is to take complexity (in the decision) off the table so that you can focus on who you want to be. It is not about the math, although there is some very powerful math at your disposal if the decision is complex enough to require the math. This is the ultimate opportunity every human being has through their decisions - to shape themselves through their actions.
Why is decision analysis important?

When you encounter personal or professional decisions, you can conduct a decision analysis to aid your process. This method requires using various decision-making tools to understand all aspects of the problem you aim to solve. By implementing its associated techniques, such as decision trees and expected value calculations, you can compare several options against one another for a more comprehensive decision. In this article, we explain the decision analysis process and provide examples you can use for guidance.

How does a decision tree work?
A decision tree starts at a single point (or ‘node’) which then branches (or ‘splits’) in two or more directions. Each branch offers different possible outcomes, incorporating a variety of decisions and chance events until a final outcome is achieved. When shown visually, their appearance is tree-like…hence the name!

Expected Value
- After a model is constructed, it is important to find the expected value (EV)to evaluate which decision results in the most favorable outcome. Recall that the decision trees provide all the possible outcomes in comparison to the alternatives. By calculating the expected value, we can observe the average outcomes of all decisions and then make an informed decision. To calculat…

Opening a location in either city will involve different capital expendituresand demonstrate different rates of success. Before constructing a decision tree, we will need to gather relevant data: After gathering data, we can construct the decision tree based …
