The steps involved in draw'ing a decision tree are stated below:
- Identify all decisions to be made and the order in which they must be made.
- Identify the chance events that can occur after each decision.
- Develop a tree diagram showing the sequence of decisions and chance events. The tree is constructed starting from left and moving towards right. The square box denotes a decision point at which the available strategies are considered. The circle represents the chance Node or Event, the various state of nature or outcomes emanate from this chance event.
- Obtain a probability estimate of the chances of each outcome's occurrence.
The steps to create a decision tree diagram manually are:
- As a starting point for the decision tree, draw a small square around the center of the left side of the paper.
- If the description is too large to fit the square, use legends by including a number in the tree and referencing the number to the description either at the bottom of the page or in another page
- Draw out lines (forks) to the right of the square box. Draw one line each for each possible solution to the issue, and describe the solution along the line.
- Keep the lines as far apart as possible to expand the tree later.
- Illustrate the results or the outcomes of the solution at the end of each line. If the outcome is uncertain, draw a circle.
- If the outcome leads to another issue, draw a square.
- If the issue is resolved with the solution, draw a triangle.
- Describe the outcome above the square or circle, or use legends, as appropriate.
- Repeat steps 2 through 4 for each new square at the end of the solution lines, and so on until there are no more squares, and all lines have either a circle or blank ending.
- The circles that represent uncertainty remain as they are. A good practice is to assign a probability value, or the chance of such an outcome happening.

In a traditionally drawn decision tree a circle represents?
Short answer: a circle represents a "chance node," meaning a chance to which an Expected Monetary Value (EMV) may be assigned to calculate the most likely pay-off. Explanation: according to the PMBOK Guide, 4th Ed. (pgs. 298-299), the inputs to this node are scenario probability and the EMV (expected monetary value) assigned to that chance node, from the decision node (denoted as a square on a decision tree). A chance node leads to a "net path value," otherwise known as a computed value or solution set (represented by a triangle on a decision tree). A decision tree of this type is one of the tools used to determine quantitative risk analysis used to reach a computed optimal solution using probability distributions as a basis.
What are the key differences between Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA)?
Failure Mode and Effects Analysis (FMEA) focuses on identifying potential failure modes and their effects on a system, while Fault Tree Analysis (FTA) analyzes the causes of a specific system failure by tracing back through a series of events or conditions. FMEA is proactive in preventing failures, while FTA is reactive in investigating the root causes of failures.
What are the differences between fault tree analysis and failure mode and effects analysis (FMEA)?
Fault tree analysis (FTA) and failure mode and effects analysis (FMEA) are both methods used in risk assessment, but they have different approaches. FTA focuses on identifying potential causes of a specific event or failure, while FMEA looks at the potential effects of failures in a system and how to prevent them. FTA analyzes events leading to a failure, while FMEA focuses on the consequences of failures.

What are the key differences between FTA and FMEA methodologies in risk analysis and how do they impact the overall risk management process?
FTA (Fault Tree Analysis) and FMEA (Failure Mode and Effects Analysis) are two methodologies used in risk analysis. FTA focuses on identifying potential failures in a system and analyzing how they can lead to a specific outcome, while FMEA looks at individual failure modes and their effects on the system as a whole. FTA is more focused on the overall system failure, while FMEA is more detailed in analyzing specific failure modes. The impact on the overall risk management process is that FTA helps in understanding the system-level risks, while FMEA helps in identifying and mitigating specific failure modes, leading to a more comprehensive risk management approach.
What are the advantages of decision tree analysis?
Advantages of decision tree analysis: Easy to interpret, Possible scenarios can be easily added, Value of different scenarios can be determined.
How decision tree help the manager in decision making?
A decision tree will help a manager decide which direction that he will moe the business in. e.g. if a business is looking to expand than they would be able to use a decision tree in order to come to a decision in terms of which direction they will expand in. It looks at the different expansion ideas and looks at the possible outcomes for these. It will however only show financial factors affecting the outcome as it analysis solely financial factors.
What are the tree steps to the design process?
The tree steps are oak, ash, and pine.

What is the need for separating analysis phase into lexical analysis and parsing?
Separating the analysis phase into lexical analysis and parsing helps to break down the process of interpreting the structure of a source code into more manageable steps. Lexical analysis focuses on breaking the input into tokens, which are the smallest meaningful units, while parsing constructs a parse tree or syntax tree to represent the grammatical structure of the code. This separation allows for easier maintenance, testing, and implementation of new features in the compiler or interpreter.
What quantitative techniques are applied for business analysis?
A. Quantitative Techniques with reference to time series analysis in business expansion. B. Quantitative techniques are mathematical and reproducible. Regression analysis is an example of one such technique. Statistical analysis is also an example of a quantitative technique. C. Quantitative techniques are applied for business analysis to optimize decision making IE profit maximization and cost minimization). It covers linear programming models and other special algorithms, inventory and production models; decision making process under certainty, uncertainty and risk; decision tree construction and analysis; network models; PERT and CPA business forecasting models; and computer application.

What role does a decision tree play in business decision-making?
Decision trees help managers visualize how their choices will play out within the organization. Using a decision tree, management can assess multiple options at once.

What is the minimum depth of a leaf in a decision tree?
The minimum depth of a leaf in a decision tree is typically 0, meaning that a leaf node can be at the same level as its parent node.
How is chocolate harvesting carried out and what are the key steps involved in the process?
Chocolate harvesting is typically carried out by hand in tropical regions where cacao trees grow. The key steps involved in the process include identifying ripe cacao pods, carefully cutting them from the tree, extracting the beans from the pods, fermenting and drying the beans, and finally roasting and processing them into chocolate products.
