Sensitivity and risk analysis
Recognizing that the venture profitability forecast hinges on future
developments whose occurrence can not be predicted with certainty, the decisionmaker
may
want
to
probe
further.
The
analyst
may
want
to
determine
the
impact
of
changes
in
variables
such
as
product
price,
raw
material
costs,
and
operating
costs
on the overall results. Sensitivity analysis and risk analysis are the
techniques that allow the analyst to deal with such problems.
The purpose of sensitivity analysis is to identify the variables that most
affect the outcome of a venture. Sensitivity analysis is useful for determining
consequences of a stated percentage change in a variable such as product price.
It involves specifying the possible range for the variable, such as price, and
calculating the effect of changes in this variable to profitability. With such a
calculation, the analyst can determine the relative importance of each of the
variables to profitability. However, only risk analysis can provide any indication of
the likelihood that such events (change in product price) will actually occur.
Risk analysis takes into account the recognized fact that variables, such as
product price, depend on future events whose occurrence can not be predicted
with certainty. Hence, investment decision situations can be characterized with
respect to certainty, risk and uncertainty. Since certainty seldom exists for future
returns on investment, only risk and uncertainty are of interest. Uncertainty is
used to refer to an event, such as technological breakthrough resulting in
obsolescence, that is expected to take place although the probability
