Use of these root causes may result in customers asking for further clarification or investigation because they are not specific and lend themselves to narrow corrective actions that may not prevent recurrence of the nonconformance. When these are encountered, “why” should be asked at least once more to determine an underlying or more basic cause. For example, if asked why an operator error occurred, it may be determined to have been caused by the operator inadvertently selecting the wrong switch that looked similar and was close to the correct switch. This root cause would lend itself to mistake proofing that would separate or distinguish the switches to prevent recurrence.
用以上的根本原因将不可能完全避免不符合的再次发生。例如,如果问为什么操作工失误呢,可能的原因是错误的开关看起来很象正确的按钮,而操作工在选择时出错了,那根本原因应该是采用防错的方法去消除按错键的事件发生
Root causes must also be sought over which management has control. A root cause of “severe weather” does not support preventing recurrence of the nonconformance where-as root causes of inadequate contingency planning or leaking trucks do support preventing recurrence of the nonconformance.
根本原因必须是被管理层控制的,根本原因如“气候影响”不是防止问题再发生的根本原因,而根本原因应该是应急措施不够
2. Corrective actions including both: 纠正措施包括
• Corrective actions taken to determine the extent of, contain and correct (i.e fix) the specific nonconformance
• 采取纠正以消除特定的不符合
• Corrective actions taken in response to the root cause(s) to eliminate recurrence of the nonconformance. These corrective actions focus on changing a process to eliminate the root cause and thus eliminate recurrence of the
