三大改善活動(dòng)機(jī)制簡(jiǎn)潔高效，是保障精益取得成果的重要抓手，更是精益管理活動(dòng)的重中之重。該機(jī)制是作者推行精益管理活動(dòng)20多年實(shí)踐精髓的總結(jié)。本書圍繞三大機(jī)制，將這套歷經(jīng)檢驗(yàn)、行之有效的方法系統(tǒng)地整理總結(jié)出來(lái)。全書共分五篇，分別對(duì)全員經(jīng)驗(yàn)改善活動(dòng)的定義、愿景、目標(biāo)、路徑和實(shí)戰(zhàn)事例等內(nèi)容進(jìn)行敘述，并闡述了全員推行精益改善的三大機(jī)制的目的和措施，后講述了課題改善中發(fā)現(xiàn)問(wèn)題、分析問(wèn)題和解決問(wèn)題的邏輯、路徑與方法。
