17. Risk and Uncertainty Management
Xodus Develop
Global Experience
Talisman, Auk South, UK Central North Sea
Risk and Uncertainty Management
A cost / schedule risk analysis using our Value, Decision and Risk Management (VDRM) approach
Project scope
Generation of project risk register
Quantification of background risk and uncertainty
Combine risk and uncertainty – cost and schedule risk analysis
Key features
Clear indication of project risk drivers
Definition of confidence levels for project costs and completion dates
Ability to set appropriate levels of contingency
Steps taken when performing a cost / schedule risk analysis using the VDRM approach:
Generation of new or update of extant project risk register. The project risk register will capture all Threats and opportunities associated with the project and indicate which may have cost and/or schedule impact. These are chance events hence < 100% chance of existence.
Quantification of uncertainty associated with work scope. Here we allocated levels of uncertainty to the activities in the cost and schedule breakdown based on our current state of knowledge.
We then combine the risk events with the associated uncertainty of the “must do” activities and run a Monte Carlo simulation.
The S-curve graph: Here we have a delta between “Uncertainty only” and “Uncertainty plus Risk”.
The ideal situation would be to manage all the risks to get the red curve back to overlay the blue curve however this is almost impossible however with good proactive risk management we can significantly reduce the delta between the two curves.
The ideal situation would be to manage all the risks to get the red curve back (risk and uncertainty) to overlay the blue curve (uncertainty only – no risk) however this is almost impossible however with good proactive risk management we can significantly reduce the delta between the two curves.
