Description / Abstract:
SAE J2886 Design Review Based on Failure Modes (DRBFM)
Recommended Practice is intended for Automotive and Non-Automotive
applications. It describes the basic principles and processes of
DRBFM including planning, preparation, change point FMEA, design
reviews, decisions based on actions completed, and feedback loops
to other processes, such as design, validation and process
guidelines (Appendix B - DRBFM Process Map).
The intent of each fundamental step of the DRBFM methodology is
presented. It is intended for use by organizations whose product
development processes currently (or intend to) use Failure Mode
Effects Analysis (FMEA) or DRBFM as a tool for assessing the
potential risk and reliability of system elements (product or
process) or as part of their product improvement processes.
DRBFM is not intended to replace FMEA however, companies
interested in adopting DRBFM will benefit from the focus on
specific change points and supporting engineering decisions based
on detailed discussions. DRBFM is a change in company culture that
requires management commitment to changing the mind set of
employees to drill deep and continually ask the question "What
Else". The DRBFM user is responsible for following this recommended
practice as well as corporate policies. Alternative documentation
formats are provided to meet the intent of the recommended
practice.
Purpose
The purpose of SAE J2886 is to establish a basic understanding
of the DRBFM process in order to promote the value of the DRBFM
method and mind set. The DRBFM value is in the mind set of
promoting good design, good discussion and good design review to
find "deeper" risks. The reader should be aware that the DRBFM
process should mature with usage, thus there is no one perfect
process. The process description outlined below is a suggested
starting point to be refined over time by the user and to be
refined as the culture, creativity and knowledge of the user
matures.
