This course is a summary of the problem solving process that was formerly known as PEP (People Eliminating Problems) within the ride control business unit and QUIP (Quality Improvement Process) within the exhaust business unit. Ford Motor Company is acknowledged as the developer of the ―8D‖ process. ) 該課程由一個(gè)由天納克員工組成的,在過去的 1520年內(nèi)致力于解決各種問題的團(tuán)隊(duì)開發(fā)的,是對解決問題程序的總結(jié)。這一程序以前在減震系統(tǒng)業(yè)務(wù)中被稱為 PEP(消除問題團(tuán)隊(duì) ), 在排氣系統(tǒng)業(yè)務(wù)中被稱為QUIP(質(zhì)量改進(jìn)程序 )。 Thanks to Kay Shreve (Monroe, MI), Michael Brown (Paragould, AR) and Eunice Spradlin (Cozad, NE) for their work on this project. 感謝 Kay Shreve (Monroe, MI), Michael Brown (Paragould, AR) 和 Eunice Spradlin (Cozad, NE) 對此項(xiàng)目所作的工作。 首次發(fā)生在 00 年 3 月1 日,以后每天每班都會(huì)發(fā)生。目標(biāo)為 3% 。 Tenneco Automotive 8D/2022 14 D2 Describe the Issue Inco rrect 不正確 Co rrect 正確 It i s n o isy 噪音太大 Bu s h i n g 3 8 4 2 7 p ro d u ce s a ― cl i ck i n g ‖ s o u n d – mea s u re s 6 d eci b el s i n t h e s o u n d b o o t h .
