FMEA is a problem solving process adopted by Snapon as a key ponent of the Quality Forward System. ? Generally, FMEA is done by an onsite multifunctional team facilitated locally or by an SEQ Group Advanced Quality Engineer. ? Objective is to identify all of the reasons why quality of a process or product does not meet expectations. ? Uses severity, occurrence and detection ratings to determine corrective action priority for each possible failure reason. Q u ality Forw ard SystemWhen should a FMEA study be conducted? ? As part of a Design/Development phase. ? When corrective action is needed due to unfavorable performance data – (performance based on QFS metrics does not meet goals). ? When a need to make incremental improvement is identified by facility management or the SEQ Group. Q u ality Forw ard SystemFMEA Team StartUp ? Team Selection – done by local quality coordinator, business unit manager or, on request, SEQ Group Advanced Quality Engineer. ? Problem Statement – A concise and focused description of the quality problem or opportunity for improvement, “what went wrong” or “what needs fixing”. ? Goal Statement – a description of what is to be acplished by the team, in quantifiable terms “reduce by”, “increase by”, “eliminate”, etc. Good metrics to use include scrap cost, rework cost, or Defects Per Million Opportunities (DPMO), etc. For example, a goal statement could be “To reduce DPMO on product family X from 3000 to 2023 by year end”. ? Complete FMEA Team StartUp Worksheet (example located in procedure SEQ , Figure 1). Q u ality Forw ard SystemProblem Statement Goal Statement ? Problem Statement and Goal Statement should consider: ? What went wrong? ? What is the gap between the desired quality level and the actual quality level? ? Which process or processes are involved? ? Which department or cell is the deficiency occurring in? ? Is the problem cyclic, can it be attributed to specific events? ? What are the appropriate metrics to measure? ? What is the impact on operational fitness and profitability? ? What is the impact on the bottom line (reduced, increased, eliminated)? ? Are there constraints recognized early in the process? If so, have they been explored and clarified with the appropriate management level Q u ality Forw ard SystemFMEA Process ? FMEA’s uncover process problems related to the manufacture of product. ? Examples: a piece of automated assembly equipment may misfeed parts resulting in products not being assembled correctly, or, in a chemical manufacturing proc
