識別消費(fèi)最多時間或資源的步驟

Identifythestepsthatconsumethemosttimeorresources.

識別太費(fèi)時間或者所需時間變化很大的流程

Identifyprocessesthattaketoolongorvarygreatlyintime.

識別延遲點(diǎn)

Identifypointsofdelay.估計每一步所增加的價值（判斷價值時，要考慮成本成因素）

考慮合并決策或者把這些決策遷移到流程中的其它位置以創(chuàng)造更多的價值Considercombiningdecisionsormovingthemtoanotherpointintheprocesstocreatemorevalue.

檢查每個重復(fù)工作的循環(huán),每個循環(huán)包含了反復(fù)的流程，考慮如何減少，消除，或者重復(fù)工作合并到另一步驟中Checkeachreworkloop.Areworkloopinvolvesiterativeprocesses,likerepeatedlycheckingacakeuntilitisdonebaking.Here,considerhowreworkcanbereduced,eliminated,orcombinedwithanotherstep.最后，再次審視每個流程步驟。有時一個流程僅僅是由于習(xí)慣而做的，而不管其有無價值Finally,lookateachprocessstepagain.Sometimesaprocessisdoneoutofhabitwithoutverifyingitsvalue確認(rèn)每個流程帶來的價值要比成本多Verifythatthestepaddsmorevaluethanitscost判段是否有冗余的流程步驟Judgeifthestepisredundant.考慮如何重新合并這些步驟以取得更高的效率Considerhowstepscouldberecombinedforgreaterefficiency11最初的流程圖InitialProcessMap12改進(jìn)后的流程圖ImprovedProcessMap福特汽車公司應(yīng)付賬款部門的工作就是接收采購部門送來的采購訂單副本、倉庫的收貨單和供應(yīng)商的發(fā)票，然后將三類票據(jù)在一起進(jìn)行核對，查看其中的14項數(shù)據(jù)是否相符，絕大部分時間被耗費(fèi)在這14項數(shù)據(jù)由于種種原因造成的不相符上。原有的業(yè)務(wù)流程如圖示。原有業(yè)務(wù)流程圖采購部門供應(yīng)商財務(wù)部門采購定單采購定單入庫單貨物倉庫付款發(fā)票重組后的業(yè)務(wù)流程圖采購部門采購定單中央數(shù)據(jù)庫發(fā)送采購定單電子數(shù)據(jù)供應(yīng)商電子付款財務(wù)部門收貨確認(rèn)倉庫貨物16價值流的繪制圖ValueStreamMapping價值流圖是流程圖的特別運(yùn)用，是建立在精益生產(chǎn)的原則上的SpecificapplicationofprocessmappingbasedonleanManufacturingprinciples系統(tǒng)的邊界一般在宏觀的層次上定義的Systemboundariestypicallydefinedatthemacrolevel.通常要比一般的流程圖包含更多的信息:Generallycontainsmoreinformationthentypicalprocessmaps:流程時間Processtime流程績效的特征Processperformancecharacteristics信息流Informationflows實(shí)物流Physicalflows17供應(yīng)鏈的設(shè)計太重要了，因而不能隨意而為。就如基因工程已開始縮短物種進(jìn)化一樣，主動的供應(yīng)鏈設(shè)計可以加快并且可永遠(yuǎn)拋棄那種緩慢的不斷臃腫的工業(yè)進(jìn)化流程。
