However there are many more in each category so use your search engine. It is often difficult to understand exactly what each one does, especially as many products present themselves as doing everything risky. The example products demonstrate this beautifully. Download the trial versions and read the tin carefully.
List risks, their owners, treatments (and their owers) and so on. Produce reports on these factors. Best working in a web-enabled fashion so that large organisations can collect and analyse their risks. Three examples are Active Risk Manager from Strategic Thought Group, Predict! Risk Controller from Risk Decisions Limited and Arrisca Enterprise Risk Manager from riskHive Limited.
Monte Carlo Toolkits
Typically work in a spreadsheet or project planning environment which is used to construct the inputs and outputs of a risk model. The toolkit provides input functions and output presentations to demonstrate and understand the results. Examples are @RISK from Palisade Inc, Predict! Risk Analyser from Risk Decisions Limited or Arrisca Enterprise Analytics from riskHive Limited. Alternatively you can use our own tool Natural Monte Carlo which you can download from our software page. For software which goes 'beyond the spreadsheet' and uses influence diagrams to construct models have a look at Analytica from Lumina Decision Systems Inc.
Integrated Project Risk Tools
Combines the functions of a planning tool, risk register and Monte Carlo toolkit for a project environment. The idea is to get you up and running quickly from a high level idea of what the project might comprise. Template risk registers might be provided which have to be used with care. An example is Risky Project from Intaver Institute.
Fault and Event Tree Tools
These provide graphical tools to develop the trees and calculational methods to estimate the risk. An example is FaultTree+ from Isograph Ltd.
These are more sophisticated analysis tools which calculate coherent sets of probabilities for a set of interelated events. They enable sensitivity studies to be carried out and the effect of new evidence to be investigated. Their starting point is simple influence diagrams: a very useful concept for framing any problem. Two examples are Hugin from Hugin Expert A/S and ArenaRisk from Agena Limited.
A similar concept to the Bayesian network tools, but focussed on the concept of the decision trees which often result from problem framing and influence diagrams. An example is DPL from Syncopation Software.
