设计评审想要有效果，DRBFM前先把这三件事做好

Core Insights - The article emphasizes the importance of proper preparation in the Design Review Based on Failure Mode (DRBFM) process to effectively prevent quality issues during the design phase [1][2][9] Preparation Steps - The preparation for DRBFM includes three key aspects: selecting appropriate participants, determining the right timing for implementation, and ensuring the team has a thorough understanding of the product [3][5][9] Participant Selection - The success of DRBFM largely depends on who is present at the meeting. A well-rounded team should include both direct technical experts and those familiar with the materials and processes involved in the product [4][9] Timing of Implementation - DRBFM should be initiated at three critical points: during the concept design phase, the detailed design phase, and when significant design changes occur. Early intervention is crucial to identify and mitigate potential risks [5][6][9] Product Understanding - A comprehensive understanding of the product is essential for effective DRBFM discussions. Participants should be well-versed in quality requirements, the product's operating environment, change points, and historical defect cases [7][8][9] Quality Requirements - Quality requirements encompass various dimensions beyond just functionality, including performance, reliability, and even aesthetic aspects [7][9] Operating Environment - Understanding the environmental pressures that products face is vital for predicting potential failure points [7][9] Change Points - Most quality issues arise from changes in design, materials, or processes. Identifying these change points is critical for risk assessment [7][9] Historical Defect Cases - Analyzing past quality issues can help prevent recurrence in new products. A database of historical defects should be prepared for reference during discussions [8][9]
