Design Review Based on Failure Mode (DRBFM)

Originally developed by Tatsuhiko Yoshimura for Toyota, DRBFM was intended to systematically analyze design changes and identify any risks and undesired effects up front. First introduced by Toyota around 1997 it is now widely used throughout industry. DRBFM is driven by a strong focus on understanding design change. Tatsuhiko Yoshimura realized problems would often arise from side effects of design changes not considered. DRBFM puts a strong focus on reviewing any potential side effects, looking at each change and invoking a discussion in a team of experts.

GD3

The process of DRBFM became also known under the term of GD3 ("Gee-Dee-Cubed"): Good Design, Good Discussion, Good Design Review. DRBFM uses an FMEA-like worksheet as a basis for discussion during design review. Typically the worksheet is printed on several A0 pages and filled with self-sticky notes by the design review team. Typically results will be captured on a computer after the workshop.

DFSS Integration

Qualica DRBFM provide a convenient way of integrating DRBFM with previous work already completed in a DFSS / QFD based process. Functional Focal Points for DRBFM can be identified through Functional Analysis. Existing FMEA data can be used as input, and DRBFM data can be used in FMEA. The Function Concern Points matrix uses the same data structure as the Design Knowledge Matrix.
