Design Review Based on Failure Mode reduces the occurrence of quality problems due to changes to products, manufacturing processes or customer applications.

Design Review Based on Failure Mode (DRBFM) was developed at Toyota in 1997. The background was the recognized challenge that quality problems can occur due to changes and amendments to products, manufacturing processes, and customer applications. DRBFM analyzes the corresponding causes and tries to reduce them.

In contrast to FMEA, DRBFM focuses on the changes and thus tries to reduce the workload.

DRBFM is often applied in these five steps:
1. Evaluation of the concept
2. Analysis of the changes
3. Identification of the failure chain (failure mode)
4. Decision on solutions (design review)
5. Implementation and verification of the action"
