Plans succeed only if the gains are sustained / 只有可以實(shí)施的計(jì)劃才是好計(jì)劃,只有堅(jiān)持執(zhí)行計(jì)劃才能成功9 There is no substitute for hard work / 努力工作,艱苦拼搏10 Just do it! / 及時(shí)行動is a manufacturing philosophy which shortens the time between the customer order and the product build / shipment by eliminating sources of waste. 是一個(gè)通過祛廢來縮短從客戶定貨到發(fā)貨周期的哲學(xué)Lean Manufacturing 精益制造Business as Usual 循規(guī)道距式經(jīng)營PRODUCTBUILT SHIPPED 生產(chǎn)并發(fā)貨生產(chǎn)并發(fā)貨CUSTOMERORDER 客戶定貨客戶定貨Time 時(shí)間Waste浪費(fèi)PRODUCTBUILT SHIPPED 生產(chǎn)并發(fā)貨生產(chǎn)并發(fā)貨CUSTOMERORDER 客戶定貨客戶定貨Time (Shorter) 縮短的時(shí)間Waste浪費(fèi)Lean Manufacturing 精益制造A TimeBased Strategy時(shí)間策略研究、開發(fā) 預(yù)先計(jì)劃 生產(chǎn) 分銷 收款實(shí)際完成的時(shí)間(從設(shè)計(jì)至收款的過程)Individual Efficiency vs. Total Efficiency單個(gè)與整體效益Pricing: The New Reality定價(jià):新的現(xiàn)實(shí)問題l The Old Model 舊公式 : Cost to make + Profit = Selling Price 制造成本+利潤=銷售價(jià)格l The New Model 新公式 :Customer sets Price Profit = Manufacturing Cost 客戶設(shè)定的價(jià)格-利潤=制造成本Leadtime 交付周期168。Value Added Activity 增值活動216。NonValue Added Activity (Waste)非增值活動 (浪費(fèi))216。Value Added Time is only a very small percentage of the Leadtime. 增值時(shí)間僅是交付周期的很少一部份168。LEAN THINKING FOCUSES ON NONVALUE ADDING ITEMS. 而精益思想則著重于 非增值項(xiàng)目Traditional vs Lean Results 傳統(tǒng)與精益之比較Traditional vs Lean Results 傳統(tǒng)與精益之比較Lean Results 精益結(jié)果Maximize ValueAdd 增值最佳化Job Analysis Results崗位分析結(jié)果Examples 例子 :?

A value added 。3. A nonvalue added step that is not required. 一種不需要的不增值步驟。? Parts get lost 零件丟失? A stack of containers fall over and parts get damaged 一疊周轉(zhuǎn)箱翻到并砸壞零件? Must use facility floor space to keep inventory 占用場地? Engineering or product change happens so inventory must be scrapped, reworked or sold at a discount 工程或產(chǎn)品更改致使庫存報(bào)廢,返工或減價(jià)買出? Sales drop so inventory must be sold at a discount to clear it out of the system 銷售大跌,只好降價(jià)清倉處理庫存?
