The aim of this paper is to provide deep insights regarding the decision tree approach and how decision tree helps the management of the organization to take right decision. In the paper the whole process of making a decision tree is described. The decision tree approach is adopted in the response of the situation which is experienced by the operational manager of cereal producer. Through creating the decision tree, the operation manager will have enough information regarding which option should be selected and how that option will create profit for the organization. Below is the complete process of developing a decision tree in detail.

2. Process of developing a decision tree

The management of the deepdrill oil rig has three options to choose from, which include deepdrill modification of old rig, renting from the pacific search, and renting from the Houston. In order to take the best project the operation manager has decided to utilize the decision tree approach. A decision tree is a decision support instrument that helps the manager of the organization to make the right decision. The decision tree approach includes various steps which are explained in detail as follows:

2.1. Drawing decision tree that represents investment options to the operation manager

The first phase of the design tree development process is to begin tree by creating the decision point and node. It means that the tree begins with a square. As there are three options available to the operation manager, three lines will be radiating from the square that will represent three options that are available to the manager (Mittal, Khanduja, & Tewari, 2017). The first can be easily understood from the following figure which represents decision options.

2.2. Adding Chance Nodes, Probability & Outcomes

The second phase of the decision tree is to add chance nodes. In the decision tree, the options have different outcomes. So the option will end with outcome (Mittal, Khanduja, & Tewari, 2017). This is marked by creating circle. The operation manager has two outcomes for the investment options, whereas the third option of no change as no outcome, so its outcome will not be shown in the decision tree (Mittal, Khanduja, & Tewari, 2017). The below figure is showing the decision tree with options & their respective probabilities.

2.3. Evaluating the expected values of Decision Tree

The third step in the decision tree making process is evaluating the expected values of the options. At the right side of the decision tree, the expected values are calculated by multiplying the probability of the options with the outcome of the option. After this the answers should be added for every option. The answers should be mentioned in the appropriate circle in the decision tree (SONG & LU, 2015). The figure below is showing the decision trees diagram with returns and outcomes.

2.4. Evaluating the Net Expected Value of Decision Tree

The last step of the decision tree process is to find out the net expected value of the options or the actual costs of the options. The initial investor, the cost of each option, is subtracted from the expected value of each option. After subtracting the cost calculations are presented on the decision tree (Mittal, Khanduja, & Tewari, 2017). Those options will be rejected which have lower net expected value and that option will be selected which has the highest net expected value. The decision regarding the option is taken on the basis of net expected value of the option (SONG & LU, 2015). The below figure is showing a complete decision tree diagram.

3. Final Decision for Operation Manager of Decision Tree

If the complete decision tree is analyzed critically than it can be seen that the large scale investment have the net expected value of 0.56 million which is higher than the net expected value of small scale project that is Houston 0.075 million (Mittal, Khanduja, & Tewari, 2017). Therefore it is advised to the operational manager to pacific rent because it has a higher net expected value than the Houston rent option. The small scale project and continue without change options should be rejected, and large scale investment should be perused because this decision will be more profitable than other decisions (Mittal, Khanduja, & Tewari, 2017).

It is recommended to the management of the deep drill to go with the decision of pacific rent because it will be more economical for the deep drill. The pacific rent will be less expensive for the deepdrill as compare to other alternatives. If all the alternatives are analyzed than it is evident that pacific rent option is the cheapest of all of the other options. After selecting this alternative it is clear that the cost of the organization won’t increase up to lot of extent. If any other option is going to be selected than there is chance that the expenses of the company will increase dramatically.

The aim of every business is to generate profit and the organization can generate profit only when it makes rational and economical decisions. Selecting pacific would be an economical decision because through this not only the corporation can save expenses significantly but also will be able to increase its profit as well no other option will provide this opportunity to the company to increase its profit up to that much of an extent. Therefore the decision tree have provided the answer of the problem which the organization was facing.

4.Conclusion of Decision Tree

It is concluded that the management of the deepdrill oil rig has three options to choose from, which include deep drill modification of old rig, renting from the pacific search, and renting from the Houston. In order to take the best project the operation manager has decided to utilize the decision tree approach. A decision tree is a decision support instrument that helps the manager of the organization to make the right decision. If the complete decision tree is analyzed critically than it can be seen that the large scale investment have the net expected value of 0.56 million which is higher than the net expected value of small scale project that is Houston 0.075 million. Therefore it is advised to the operational manager to pacific rent because it has a higher net expected value than the Houston rent option. . The decision tree approach is adopted in the response of the situation which is experienced by the operational manager of cereal producer. Through creating the decision tree, the operation manager will have enough information regarding which option should be selected and how that option will create profit for the organization.
