SENG 312 - T4: RISK ASSESSMENT MATRIX
Risk Assessment Matrix - Answer -increase visibility of risks and assist management
decision making
Y-Axis: Severity ($)
X-Axis: Probability
log-log axis
Iso-Risk Curves - Answer -Y-Axis: Severity($)
X-Axis: Probability
Ri = Pi*Ri
logR = LogS + LogP
LogS = -LogP + LogR
just lines on graph (no color)
Probability of Mishap From Hazard (Used on graphing) - Answer -1.0E-7 to 0.1
Severity - Answer -$1,000,000 < 1 < $100,000 [Catastrophic]
$100,000 < 2 < $10,000 [Critical]
$10,000 < 3 < $1,000 [Marginal]
$1,000 < 4 < $100 [Insignificant]
Probability - Answer -0.1 < A < 0.01 [Frequent]
0.01 < B < 0.001 [Probable]
0.001 < C < 0.0001 [Occasional]
0.0001 < D < 0.00001 [Remote]
[T/F] Probability describes the whole incident - Answer -False
Severity Categories - Answer -1) Catastrophic [Death; Loss of system]
2) Critical [Severe injury/damage]
3) Marginal [Minorinjury/damage]
