If you have performed a Design FMEA, you might be familiar with the terms “Current Prevention Controls” and “Current Detection Controls” that is used in the template. FMEA is typically performed as per AIAG-VDA FMEA standard. This standard defines the meaning and purpose of these terms. FMEA is performed for both Design and Processes. Design FMEAs are performed for the Product, System, HW or SW. In the parallel Functional Safety world, similar cousin terms ‘Prevention Measures’ and ‘Detection Measures’ are commonly used. However, there is no fixed definition to these terms in ISO26262 (i.e., you wouldn’t be able to find these terms defined in Part-1). The terms are much more understood logically in the context of functional safety. The goal of this article is to help the reader understand what these terms in these two worlds mean. The article will also explain how the AIAG VDA FMEA standard has bridged the functional safety gap in its 2019 edition. “Current Prevention Controls” and “Cu...
