Final answer:
The decision tree evaluation determines that the firm should expand to a new site. However, further analysis and consideration of other factors are recommended before making a final decision.
Step-by-step explanation:
a. Construct a decision tree:
- The decision tree consists of three options: expand at current site, expand to a new site, or do nothing.
- Draw a square as the starting point and label it 'Evaluate options'.
- From this square, draw three branches labeled 'Expand at current site', 'Expand to a new site', and 'Do nothing'.
- From each of these branches, draw two branches representing the two types of growth: strong growth and weak growth.
- Attach the corresponding costs and revenues to each branch according to the given probabilities and values.
- Continue branching out and assigning probabilities and values until all possible outcomes are accounted for.
b. Solve the tree:
- Calculate the expected value for each leaf node by multiplying the probability by the revenue and subtracting the cost.
- Work backward through the tree, calculating the expected value at each decision node by taking the maximum value of the corresponding leaf nodes.
- Continue this process until you reach the starting point, where you will have the expected value for each option.
c. Decision based on the evaluation:
- The option with the highest expected value is the recommended decision, as it represents the best outcome considering the given probabilities and values.
- In this case, the decision tree evaluation shows that the firm should expand to a new site as it has the highest expected value compared to the other options.
d. Critical thinking on the decision:
- However, it's important to consider other factors that may influence the decision, such as market conditions, competition, and potential risks.
- It's also advisable to conduct further analysis and research to validate the findings of the decision tree evaluation and ensure a comprehensive understanding of the potential outcomes.
