•
Risk probability number (RPN) = O x S x D
•
Risk acceptance threshold RPN < 125
FMEA
methodology
Ordinal scales should
not be subject to
arithmetic operations
•
RPN > 125 and high S value
→
additional safety measures
required with a priority based on
- expected RPN reduction
- Feasibility (costs, resources, routine implementation)
- Define deadlines!
