1. A method of evaluating a criticality of a system parameter comprising:
- evaluating potential consequences resulting from an absence of a system value;
identifying alternate means of obtaining information determined utilizing the system parameter;
assigning an importance to the system parameter; and
adjusting at least one means of obtaining the system parameter responsive to the evaluation of possible consequences and alternate means of obtaining information.

Abstract
A method and system of evaluating the criticality of parameters by evaluating consequences of a loss of capability to determine a desired operating parameter, identification of alternate means of obtaining the parameter, and assigning an importance value to the capability of determining the operating parameter. The resulting evaluation and identification is utilized to direct design and mitigation efforts.
