Introduction: The module objective is to demonstrate a number of basic and intermediate tools from @RISK that are relevant to current practices used in the world of project management.
Contingency and management reserves are established to respond to risks so that risks do not compromise the project.
Defining event risks that may or may not occur and may have an impact on the project.
Expected Monetary Value is a methodology to calculate contingency reserve by calculating means or averages.
Using @RISK we use three parameter points: a minimum, a most likely or mode value and a maximum in order to recognize the varying nature of activities.
We continue using a PERT function to insert unit price and quantity variation on activities.
A typical category of event risk that either happens or not. It is binary in nature.
Handling a risk that is not binary in nature. The bankruptcy of any number of sub-contractors is a mult-frequency type of risk.
Inserting a COMPOUND distribution to correctly handle multi-frequency risks with varying impacts for each potential bankruptcy.
A third type of event risk, called Multiple Frequency Single type of event. An event may occur or not a number of times during a certain time period or project.
Defining outputs and simulation settings before running a simulation.
After a simulation has been run we start interpreting histograms for output variables.
The idea of using tornado graphs is to perform sensitivity analysis. They display a ranking of the input distributions that impact a certain output.
This powerful function allows synthesizing several input variables into a single bar on a tornado chart.
A favorite tornado that does not use coefficients and is preferred by many decision makers.
A tornado graph charting "regression coefficients" and showing the magnitudes of the bars "normalized" by the standard deviation.
Scatterplots show the relationship between two different input variables.
A tornado chart with Spearman Rank Correlation Coefficient assumes non-linearity on the calculation of such an index.
This type of tornado graph normalizes bars expressed in units of standard deviation change in the respective input.
This tornado graphs shows the amount of change in the output attributable to each input.
A spider graph shows how the value of the output statistic changes as the sampled input value changes.
Statistics functions return desired statistics on simulation results for simulation outputs or inputs.
This functionality allows you to add a graph of simulation results to a worksheet.
We present here an integrated business case for calculating a simplified project cost estimation. An integrated case for calculating a simplified project cost and its probabilistic contingency reserve estimation. Quantification of price and quantity risk as well as event risks. The objective of presenting this example is to demonstrate a number of basic and intermediate tools from @RISK that are relevant to current practices used in the world of project management. The goal is to show how @RISK tools can be used to represent quantitative – not qualitative – risk analysis.
