Failure Mode and Effect Analysis (FMEA)
Established by US military in 1949
analysis starts from component level of system
Mitigation 2: Choosing proper procedure
A Scale of severity from low to high noted
Mitigation 1: proper establishment of strategy
According to severity, number of mitigation plans to develop is decided.
Probability of the below failures should be noted
Three variables are calculated
Calculated in terms of index score called risk criticality number
severity
Risk criticlity number ranges from 1 to 1000
Probability of occurrence
level of detection or control
list of tries effecting above failure modes
Based on number mitigation plan developed
Chances of failures should be listed
Factors effecting the modes are considered
Mitigation 3: Development of contingency plan
List of potential failure modes are compiled.
Multiplying three variables
