Describe the benefits and limitations of both Sensitivity Analysis and Scenario Analysis
Sensitivity analysis
Sensitivity analysis is used to determine how the value of a
dependent variable changes when we use various values of an
independent variable.
Advantages:
i)In case of sensitivity analysis, a decision maker needs to
identify the variables that affects the forecast of cash flows and
this helps the decision maker to understand the project in
totality.
ii)In helps in identifying the incorrect forecasts and in this way
it helps the decision maker to focus on the relevant variables.
Limitations:
i)We cannot expect clear cut results from sensitivity
analysis.
ii)We analyze each variable separately in sensitivity analysis, so
it doesn't focus on the interrelationship between the underlying
variables.
Scenario Analysis
Scenario analysis is a technique used to calculate the value of an
investment by taking into consideration a variety of scenarios or
future possibilities like worst case scenario, average case
scenario and best case scenario.
Benefits:
i)Scenario analysis helps in business decision making as it takes
into account possible future events in the business.
ii)It helps in developing mitigation strategies and also
contingency plans in case of insurers or insurance companies.
iii)Using scenario analysis we can have a range of values that will
refer to the how much the stock value will be under various
scenarios.
Limitations:
i)It cannot measure accurately the by products of major factor
movements (factors of production, movements of labor, capital
etc)
ii)Scenario analysis depends heavily on the quality of the model,
the quality of the data used for scenario analysis, and the quality
of the team working on scenario analysis. For example, if the data
quality is poor, the result will mostly be incorrect and also
unreliable.
iii)Scenario analysis needs continuous revision, control and
refinement by a group of experts.
iv)The outcome sets in a scenario analysis will be bounded by the
values of extreme events which can be both positive and negative
events.
