Aspects in FMEA Grid

Structure analysis (step 2)

Process Item

The Process Item of the PFMEA is the up most level of the PFMEA.  In AVIX this is always an assembly Line. 

Process Step

The process step is an work station or a manufacturing operation. It is also considered to be the focus element of the PFMEA. In AVIX the process step and the focus element is separated. The process step is the Workstation and the focus element is the Process Task.

Process Work Element

Function analysis (step 3)

1. Function of the Process Item

2. Function of Process Step

3. Function of Work Element

Failure Analysis (step4)

1. Failure Effects (FE)

Severity

2. Failure Mode of Process Step

3. Failure Cause of the Work Element

Risk analysis (step 5)

Current prevention control (PC) of FC

Occurrence

Current detection control (DC) of FC

Detectability

Action priority
