43. Sometimes called a sensitivity analysis, a what-if analysis allows you to study how changing one or more values affects the results. Please briefly describe the following terms related to performing a what-if analysis: decision variables, constants, and output variables.

Constants are elements that are not likely to change much over time. They do not vary in a what-if analysis.

Output variables are values in the results that could change if the decision variables change. Output variables are often referred to as dependent variables because their value depends on the independent variables. These are the results that you are calculating and studying with the what-if analysis.

44. Decision trees are made up of three primary elements: Uncertainties, Decisions, and Results. For each decision tree elements please indicate the shape that represents that element and a description of how that element is used in creating values for each option.

Uncertainties are represented by circles

• Multiply each outcome by its probability

• Insert this value in the decision tree

• Repeat this for each uncertainty

Decisions are represented by squares

• Estimate the costs associated with each option

• Subtract cost of the outcome value you calculated to find the benefit of that decision

• Repeat this for each decision

Results are represented by a line

• When you have calculated all of the decision benefits (value–cost), choose the option that has the largest benefit. This is the optimal decision.
