ProRisk is a project steering aiding tool through a better risks management inside the project. Its objectives are to assist the global project risk level evaluation on one hand, and to help choosing the best response strategies (mitigation) on the other.
For this purpose, its relies on project’s scenarios generation and evaluation techniques.
The implementation process of ProRisk is carried out in three steps:
- Modeling of the project, risks and strategies,
- The generation and the evolution of project’s scenarios,
- The decision aiding.
In the modeling phase, ProRisk is based on four modelers:
- Project modeler: allows to model project’s parameters,
- Task modeler: allows to model tasks of the project in the form of PERT network, as well as those of risks’ treatment actions,
- Resource Modeler: allows to model mobilized resources to carry out tasks.
The generation and evaluation phase allows identifying all scenarios of the project in regard to:
- The occurrence or none occurrence of some risks (risks scenarios),
- Possible corrective or preventive treatment strategies (treatment scenarios).
A project scenario is a possible way to perform the project.
Then, every scenario is evaluated according many criteria in order to compare them. Used criteria are for instance, the occurrence probability of the scenario, the cost and the duration.
In the decision-aiding phase, ProRisk propose to the user many visualization of the results. So, results could be represented in the form of tables, or graphics (bubble charts, decision trees, histograms). The user can then conduits his analysis by identifying:
- The most relevant scenarios: scenarios to which the project has to be oriented, while striving preventives strategies that lead to these scenarios,
- Scenarios to avoid,
- The global risk level of the project: final uncertainty about the total duration and/or about the total cost,
- The confidence level on the objectives fulfillment: number of scenarios that overpass delay and cost objectives.
