FMEA methodology

Ordinal scales should not be subject to arithmetic operations

• Risk probability number (RPN) = O x S x D

• Risk acceptance threshold RPN < 125

• 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!

Check the effect!
