1. A system for assessing risk of an operation of a user comprising: a storage device; an operational safety risk input interface for receiving operational safety risk information from the user or from other systems of the operation, said operational safety risk information stored in the storage device and indicative of an operational safety risk measurement of the operation; a conditional safety risk input interface for receiving conditional safety risk information from the user or from other systems of the operation, said conditional safety risk information stored in the storage device and indicative of a conditional safety risk measurement of the operation; a rules engine of computer executable instructions stored in the storage device, said rules engine for determining at least one of an operational safety risk measurement for the operation as a function of the operational safety risk measurement information stored in the storage device and a conditional safety risk measurement for the operation as a function of the conditional safety risk measurement information stored in the storage device; a processor connected to the storage device and executing the rules engine instructions for determining a safety risk analysis measurement based on at least one of the determined operational safety risk measurement for the operation and the determined conditional safety risk measurement for the operation; and a safety risk analysis measurement output interface connected to the processor and indicating the determined safety risk analysis measurement for the operation; wherein the safety risk analysis measurement is a weighted composite which is a function of the operational safety risk measurement information stored in the storage device or as a function of the conditional safety risk measurement information stored in the storage device.
