Risk Management Measure


The Safety-Impact is +50%”, Means it is 50% better than the target Level (100%).
If the Safety-Factor is 2x for a Performance-Target, then the Safety-Impact of +50% is “good”,
but it falls -50% (short) of a possible required Level of “100% over the target” (= 200% Impact)
which would be “insufficient” over-design.

The “Safety-Impact is +50%, for a performance Goal”, Means 50% over the target Level.
It Means “50% more than required by the target itself” (which is at 0% Level),
but perhaps “less than the Requirement specified by a Safety-Factor”.
The “Safety-Impact is +50%” for a Cost-Budget Means that the estimated Cost is 50% better
-50% compared to Budget-Level 0%)than it should be to meet the Budget (which is 0% Level).
So it is half the target Level.


Note 1. The Safety-Impact is a Measure that is independent of the Safety-Factor required (if any).
It is an indirect Measure of how well that a required Safety-Factor is met in theory or in practice.
It can be compared to the Safety-Factor to see how well we are doing in achieving Safety-Factor Levels.

Note 2: if the deviation is more than target for performance measures,
and less than Budget for Cost-Budget-Targets then we have “a degree of safety”.
If we are worse than the target Levels then we have a “negative Safety-Margin”.
