How would you use FMEA to ensure proper sequence of steps?
At the moment PFMEA studies the failure modes associated with each steps, but we found ourselves confused when somebody did the steps perfectly, just not in the right order. How would you tackle this?
Let's imagine a station in which an operator needs to manually stack 4 parts on to each other: A,B,C,D
We defined for him 4 functions at the Work Element level:
- Place part A on pallet
- Place part B on part A
- Place part C on stack AB
- Place part C on stack ABC
Now we already have clearly identified failures for each step, for ex:
- Doesn't place part B
- Damages part C
- Misplaces part D
but how would you handle the wrong sequence, for example: Placing C before B?
There are so many potential combinations to study. Is there a smarter and faster way to handle this?
