Introduction For A Simple Decision: It Is Either A Question
Introduction for A Simple Decision It Is Either A Question Of Taking On
Introduction For a simple decision it is either a question of taking one path or another path. With multifaceted decisions it can be a more complicated process because, one decision may affect the outcome of another decision and/or vice versa. In making decisions there also could be uncertainty and the degree of an uncertainty could affect the decisions.
Activity Instructions
To learn about decision trees in business, conduct research within the TU library databases and credible Internet resources to explain the following: Discuss the concept of a decision tree. Outline its purpose in business. Explain the advantages and disadvantages over other decision techniques. Describe how uncertainty is depicted within the tree and how it is considered within the tree to make decisions. Draw a decision tree making at least a 3-level decision: Explain the decision the tree is depicting, and how the tree can be utilized to make the decision. When drawing the decision tree, you can use the features in Microsoft Word within your paper or draw the tree on paper, take a picture of the tree, and insert the picture into the word document. If you are not familiar with the tools in Microsoft Word, it may be simpler to draw the decision tree. If you draw the tree and take a picture, make sure you make the drawing large enough, the drawing is legible and the picture you take is clear and focused.
Writing and Submission Requirements: 2-3 pages (approx. 300 words per page), not including title page or references page. Minimum of 2 references.

Decision trees are graphical representations that help in systematically analyzing complex decision-making scenarios by illustrating possible options, outcomes, and associated probabilities. They are instrumental in business for facilitating structured decision-making, especially under conditions of uncertainty. A decision tree typically starts with a decision node, followed by chance nodes representing uncertain events, and culminates in terminal nodes illustrating possible outcomes and their associated payoffs or costs.
The primary purpose of decision trees in business is to aid managers and decision-makers in evaluating different courses of action by quantifying risks and benefits and visualizing potential future scenarios. This visualization allows for more informed decision-making, especially in strategic planning, investment analysis, and operational decisions where multiple variables and uncertain outcomes are involved.
Advantages and Disadvantages of Decision Trees
One of the key advantages of decision trees is their clarity and visual nature, making complex decisions more understandable and accessible. They facilitate thorough analysis by considering various options and possible outcomes systematically and can incorporate probabilities and payoffs, aiding in risk assessment. Decision trees are also flexible, allowing updates as new information becomes available, and are applicable across diverse business contexts.
However, decision trees also have disadvantages. They can become overly complex when multiple decision points and outcomes are involved, making them difficult to interpret and manage. Additionally, they rely heavily on accurate probability estimates; incorrect assumptions can lead to flawed decisions. Building an extensive decision tree can also be time-consuming and computationally intensive, especially for decisions involving many variables and potential outcomes.
Depiction and Consideration of Uncertainty
Uncertainty is depicted within a decision tree through chance nodes, which represent uncertain events with associated probabilities. These probabilities reflect the likelihood of particular outcomes and are used to calculate expected values at each terminal node. The decision maker can incorporate subjective probabilities based on historical data or expert judgment. The tree considers uncertainty by weighting the outcomes according to their probabilities, thus enabling a calculation of the expected utility or value for each decision path.
In decision-making, uncertainty is incorporated by assigning probabilities to the chance nodes and utilizing these to evaluate the expected payoff of different options. Decision-makers can compare outcomes based on their expected values, thus selecting the option with the highest expected benefit while accounting for risk. Sensitivity analysis can further assess how changes in probabilities influence the decision, enhancing robustness.
Example of a 3-Level Decision Tree
To illustrate, consider a business deciding whether to launch a new product. The first decision node involves choosing to launch or not. If they launch, the next chance node assesses market response as successful or unsuccessful, with associated probabilities. The final level considers financial outcomes, such as profit or loss, based on prior choices and market responses.
This decision tree helps visualize the risks and rewards inherent in the decision. It quantifies potential outcomes, facilitating a rational choice based on expected monetary value calculations. For instance, if launching offers a high probability of success with substantial profit, the tree’s analysis supports proceeding with the launch. Conversely, if risks outweigh rewards, the business can decide to hold off.
In practice, decision trees are valuable because they provide a visual and quantitative framework for complex decisions. They enable managers to evaluate each possible outcome systematically, incorporate uncertainties, and select strategies that optimize their objective, such as profit maximization or risk minimization.
Conclusion
In conclusion, decision trees are vital decision-support tools in modern business contexts. They offer clarity through visualization, account for uncertainties via probabilistic analysis, and aid in maximizing expected benefits. Although they have limitations, their strategic application facilitates better decision outcomes under uncertainty, making them indispensable in various business scenarios.
