Ithiyori yeZithintelo: "UkuKhanya okuBlue" ukudala amandla angenanto (2007)

Inkohliso eyiNgozi yokugcina wonke umntu exakekile

Ngo-2007, umanejala womgangatho wokwenza izinto wafaka izibane zesilumkiso eziluhlaza ngaphezu kwawo wonke umatshini kwiziko lakhe. Izibane zazikhanyisa ngalo lonke ixesha indawo yokusebenza ihleli ingasebenzi ngaphezulu kwemizuzu emithathu. Indlela awayeqiqa ngayo yayibonakala isengqiqweni: oomatshini abangasebenziyo babethetha ukumoshakala kwamandla, yaye ukumosha kwakhe kwakuthetha ukulahleka kwengeniso. Kwisithuba seeveki ezintandathu, wonke umatshini wawusebenza kufutshane ne-100% yokusetyenziswa. Kwisithuba seenyanga ezintathu, umgangatho wefektri wawutshonelwa kuluhlu lweempahla ezisaqhubekayo, amaxesha okukhokela aye aphindaphindeka kathathu, kwaye ukuhanjiswa kwangethuba kuye kwawa ukusuka kuma-92% ukuya kuma-61%. Izibane eziluhlaza zenze kanye loo nto beziyilelwe ukuba ziyenze - kwaye zaphantse zalitshabalalisa ishishini.

Eli bali, lisekelwe kwiTheory of Constraints (TOC) ka-Eli Goldratt, liye laba lelinye lamabali anamandla okulumkisa kulawulo lwemisebenzi. Ibonisa inyaniso ephikisayo ukuba iinkokeli ezininzi zoshishino zisenzima ukuyamkela:ukwandisa ukusetyenziswa kwezibonelelo zonke kwinkqubo yakho ayiphuculi inkqubo - iyayichitha.Into ethi "Blue Light" ayikho nje ingxaki yokuvelisa. Ihlala kuwo onke amasebe, yonke ideshibhodi ye-SaaS, kunye nethuku lomphathi ngalinye ukugcina iqela labo lixakekile okokoko.

Yintoni eneneni iThiyori yeZithintelo isixelela yona

Ithiyori yeZithintelo ka-Eli Goldratt, eyaqala ukuqaliswa kwinoveli yakhe ye-1984Injongo, ixhomekeke kwisiseko esilula esikhohlisayo: yonke inkqubo inomqobo omnye ubuncinane - i-bottleneck - ethintela ukugqithiswa komsebenzi wonke. Ukusebenza kwenkqubo yonke akumiselwanga ngomgangatho wokusebenza kwamalungu ayo, kodwa ngokusebenza kwelona khonkco linye libuthathaka. Ityathanga lomelele kuphela njengelona khonkco libuthathaka, kwaye ishishini likhawuleza kuphela njengenkqubo yalo ecothayo ebalulekileyo.

Amanyathelo amahlanu okugxila kwe-TOC aqondile: chonga isithintelo, sisebenzise ngokupheleleyo, sithobe yonke enye into kuyo, siphakamise isithintelo ukuba siyimfuneko, kwaye uphinde. Eyona nto ikhwelisa imibutho emininzi linyathelo lesithathu - ukuzithoba. Kuthetha ukuba izibonelelo ezingekho phantsi kweebhotile kufunekahayizisebenze ngokuzeleyo. Kufuneka basebenze ngesantya esichazwe ngumqobo, kwaye bangakhawulezi. Nasiphi na isiphumo esingaphaya kwento enokuthi ifunwe ngumqobo iba yi-inventri egqithisileyo, nokuba olo luhlu lwempahla luthatha uhlobo lwempahla ebonakalayo, amatikiti enkxaso angalungiswanga, iiprojekthi ezigqitywe ngesiqingatha, okanye imisebenzi ekroliweyo kwisixhobo solawulo lweprojekthi.

Apha kulapho ukukhanya okuluhlaza kungena emfanekisweni. Xa abaphathi belinganisa kwaye bavuze ukusetyenziswa kuzo zonke iindawo kwinkqubo, bakhuthaza imveliso egqithisileyo kwimithombo engasebenziyo. Isiphumo sisixokelelwano esixineneyo ngumsebenzi ogqityiweyo ngokungaphelelanga, amaxesha omjikelo omde, kunye nesiphithiphithi esidida ingcinga eqhelekileyo: wonke umntu uxakeke kakhulu kunangaphambili, kodwa kuncinane okwenzekayo ngokwenene.

Ukudala Isakhono salo Nto: Iindleko zokwenyani

Ibinzana elithi "ukudala amandla ento" libamba ingundoqo yomgibe wokukhanya okuluhlaza. Xa umatshini ongengo-bottleneck okanye ilungu leqela linexesha elingasebenziyo, liziva liyinkcitho. Kodwa elo xesha lingasebenziyo aliyonkcitho-yimfuneko yezibalo. Ukuba i-bottleneck esezantsi ingakwazi ukucubungula iiyunithi ezili-100 ngeyure, kwaye i-non-bottleneck enyukayo ingakwazi ukucubungula iiyunithi ze-150 ngeyure, ukuqhuba i-resource upstream ngesantya esipheleleyo kuvelisa iiyunithi ze-50 ngeyure yoluhlu olungenandawo yokuya. Phindaphinda-phinda oko kumaziko omsebenzi asibhozo kunye neshifti yeeyure ezilishumi, kwaye uvelise iiyunithi ezingama-4,000 zomsebenzi oqhubekayo otya indawo yomgangatho, uhoyo lolawulo, kunye nemali yokusebenza ngelixa uhambisa i-zero eyongezelelweyo.

Uphononongo luka-2018 olwenziwa yi-Lean Enterprise Institute lufumene ukuba abavelisi abalandela ukusetyenziswa okuphezulu kwendawo yonke bathwala, ngokomyinge, i-2.7 amaxesha angaphezulu kwe-inventory eqhubekayo yokusebenzakunabo balawula ukuhamba ngokusekwe ekuchongeni umqobo. Uluhlu lwempahla olugqithisileyo lonyuse amaxesha okukhokela okuli-avareji ngama-340% kwaye lufuna i-23% yeeyure zomsebenzi ezongezelelekileyo zokukhawulezisa, ukuphatha imathiriyeli, kunye nokusetyenzwa kwakhona komgangatho. Ukukhanya okuluhlaza, okucetyelwe ukuphelisa inkunkuma, kuye kwaba yeyona generator inkulu yayo.

Impembelelo yezemali idlulela ngaphaya kweendleko ezithe ngqo. Umsebenzi omninzi osaqhubekayo ubophelela imali enokuthi isetyenziswe kwenye indawo. Idala iingxaki ezisemgangathweni njengoko izinto zihlala emgceni kwaye zithobe okanye ziphelelwe lixesha. Idala ukudideka malunga nezinto eziphambili, kuba xa yonke into iqhubeka, akukho nto ingxamisekileyo ngokucacileyo. Kwaye ithoba isidima amaqela asebenza nzima kwikota nganye ngelixa iziphumo zidodobala okanye zisehla.

Ukukhanya okuBlue kuMsebenzi woLwazi kunye neShishini lanamhlanje

Ngelixa ibali lokukhanya okuluhlaza okwesibhakabhaka livela kwimveliso, isenzeko siyingozi kakhulu kumsebenzi wolwazi kunye namashishini eenkonzo. Qwalasela i-arhente yokuthengisa apho ilungu ngalinye leqela lilandelwa ngokusetyenziswa okuhlawulelwayo. Abaqulunqi, ababhali, kunye neengcali zobuchule ziyatyhalwa ukuba zigcine ama-85-95% amaxabiso okusetyenziswa. Isiphumo? Iiprojekthi ziyafumba kwimigca elindele ukuphononongwa kumlawuli omnye woyilo (umqobo). Abayili bawugqiba ngokukhawuleza umsebenzi kunokuba unokujongwa kwakhona, nto leyo ekhokelela kumjikelo wohlaziyo apho imeko ilahlekileyo, ingxelo iphelelwe lixesha, kwaye ukuphinda kusetyenzwe kube yinto eqhelekileyo kunomkhethe.

Umzekelo ofanayo uvela kumaqela ophuhliso lwesoftware alinganiswe ngesantya okanye amanqaku ebali nge-sprint, amaqela athengisayo alinganiswe kwivolumu yomnxeba kunokuguqulwa, kunye namaqela axhasayo alinganiswe kwiitikiti ezivuliwe kunokuba amathikithi asombululwe ngokwanelisayo. Kwimeko nganye, i-metric ikhuthaza umsebenzi wasekhaya endaweni yenkqubo yogqibo.

• Amaqela eSoftware: Abaphuhlisi batyhala ikhowudi ngokukhawuleza kunokuba i-QA inokuyivavanya, ukudala umva okhulayo weempawu ezingavavanywanga kunye nokunyusa izinga lesiphako ukuya kuthi ga kwi-40%
• Imibutho yokuthengisa: I-Reps ivelisa iziphakamiso ezininzi kunokuba imisebenzi inokuzalisekisa, ekhokelela kwizithembiso zokuhanjiswa okuphulwayo kunye nokunyuka kwe-15-25% kwi-churn yabathengi
• Amasebe e-HR: Abaqeshwa bafumana abaviwa abaninzi kunokuba abaphathi baqeshe udliwano-ndlebe, nto leyo ekhokelela ekubeni abafundi abaqeqeshiweyo bayeke imibhobho efikelela kwiintsuku ezingama-45+.
• Amaqela ezemali: Abaprosesa be-invoyisi basebenza ngee-akhawunti ezihlawulwa ngokukhawuleza kunokuba abavumayo banokugunyazisa, bedala imiqobo eyonakalisa ubudlelwane bomthengisi
• Impumelelo yoMthengi: Iingcali zokukhwela zingxamela ukuseta okokuqala ngokukhawuleza kunokuba abathengi banokufunxa, nto leyo ekhokelela ekwehleni kwamazinga okuthathwa kwabantwana nge-30%

Kuyo yonke imeko, isibonelelo esingathinteli siziva sinemveliso. Iideshibhodi zibonisa eluhlaza. Ukusetyenziswa kweemetrics kufikelele kwiithagethi. Kodwa inkqubo iyonke inikezela ngexabiso elingaphantsi kumthengi, kwaye abantu abenza umsebenzi baziva ngathi kukho uqhawulo phakathi komzamo wabo kunye neziphumo ezinentsingiselo.

Ukuchonga uMnyanzelo Wakho Wokwenyani phambi kokuba Uyiphucule

Inyathelo lokuqala lokuphuma kumgibe wokukhanya okuluhlaza kukuchongwa komqobo onyanisekileyo. Uninzi lwemibutho lunqumla eli nyathelo kuba lifuna ukuvuma ukubaakukho zonke izixhobo ezibaluleke ngokulinganayo kwi- throughput- isiphelo esiziva siyingozi kwezopolitiko. Akukho ntloko yesebe ifuna ukuva ukuba iqela labo alinamsebenzi kwaye kufuneka ngamanye amaxesha lingenzi nto.

"Iyure elahlekileyo kwi-bottleneck yiyure elahlekileyo kwinkqubo yonke. Iyure egcinwe kwi-non-bottleneck yi-mirage - idala inkohliso yenkqubela phambili ngelixa ivelisa enye into ngaphandle kwe-inventory engaphezulu kunye nengxolo yokusebenza."

Ukufumana isithintelo sakho, khangela iziko lomsebenzi elinomgca omde phambi kwalo. Kwimeko yokwenziwa kwemveliso, ngowona matshini unomsebenzi osaqhubekayo opakishwe ecaleni kwawo. Kwishishini lenkonzo, ngumntu okanye iqela elilindelwe ngumntu wonke. Kumsebenzi wedijithali, linqanaba apho imisebenzi iqokelelana kunye nobudala. Iimpawu eziqhelekileyo zibandakanya: ukunyuka kwamaxesha okukhokela nangona amanqanaba omsebenzi azinzile okanye anyukayo, ukukhawulezisa rhoqo okanye ukubeka phambili izinto eziphambili, kunye nokukhathazeka okukhulayo phakathi kwamaqela asezantsi alindele imveliso enyukayo engenako ukuyisebenzisa.

Amaqonga oshishino anamhlanje anokwenza ukuchongwa komqobo kube lula kakhulu. Xa iCRM yakho, ulawulo lweprojekthi, i-invoyisi, iHR, kunye nedatha yokusebenza ihlala kwisistim emanyeneyo efana Mewayz, ungalanda imiqobo yokuhamba komsebenzi kulo lonke ishishini kunokuba ngaphakathi kwamasebe azimeleyo. Ngeemodyuli ezidityanisiweyo ezingama-207, iMewayz inika iinkokeli zemisebenzi ukubonakala apho umsebenzi uqokelela khona ngokwenene - nokuba kukwizigaba zemibhobho yokuthengisa, umgca wamatikiti enkxaso, ukuhamba komsebenzi wokuhamba kwabasebenzi, okanye imixokelelwane yokuvunywa kwe-invoyisi - evumela ukuchongwa komqobo okuya kufuna iiveki zohlalutyo lwezandla kwisitaki sesixhobo esahluliweyo.

Ukuthotyelwa: Ukuziphatha okuPhikisayo koBuchule bokungaSebenzi

Nje ukuba uchonge isithintelo sakho, olona tshintsho lunzima lwenkcubeko luyaqala. Ukuthobela kuthetha ukuvumela ngabom izibonelelo ezingathinteliyo ukuba zisebenze ngaphantsi komthamo opheleleyo. Kuthetha ukuba umatshini onyukayo uhlala ungasebenzi xa ibhotile esezantsi inoluhlu olwaneleyo. Kuthetha ukuba umyili uyayeka ukuvelisa iikhonsepthi ezintsha xa ezintathu sele zikrolwe ukuphononongwa. Kuthetha ukuba umqeshwa uyanqumama ekufuneni xa abagqatswa abahlanu abafanelekileyo sele belindele udliwano-ndlebe oluqeshwayo lwabaphathi.

Kulapho ingqondo yokukhanya okuluhlaza kufuneka ife. Abaphathi abalungiselelwe ukulinganisa ixesha lokungenzi nto kunye nenkunkuma bayakuchasa ukuzithoba ngethuku ngalinye abanalo. Undoqo kukulungisa incoko kwakhona ukusuka kwisixhobo sokusebenza kakuhle ukuya kwimpumelelo. Ubuchule bobutyebi bubuza: "Ngaba lo mntu okanye umatshini uxakekile?" Ukusebenza kakuhle kokuhamba kubuza: "Iyunithi yomsebenzi ihamba ngokukhawuleza ukusuka ekuqaleni ukuya ekupheleni?" Ezi metrics zimbini zihlala zinxibelelana ngokungafaniyo. Uphando oluvela kuNiklas Modig noPär Åhlström olubhalwe kwiThis is Lean lufumanise ukuba imibutho ene-90%+ yemithombo yobuchule idla ngokuba nokuhamba kakuhle okungaphantsi kwe-10% — nto leyo ethetha ukuba umsebenzi owawufuna iyure enye yomsebenzi wokwenene uthatha iiyure ezilishumi okanye ngaphezulu ukugqiba xa amaxesha emigca ebandakanyiwe.

Ukuthotyelwa okusebenzayo kujongeka njengee-sprint buffers ezicwangcisiweyo kumaqela esoftware, ukukhutshwa okulawulwayo kweentengiso kukhokelela kumthamo wokufezekiswa komdlalo, izithuba zangabom zokukhwela umxumi ukuze utshatise impumelelo yeqela le-bandwidth, kunye nokuvalwa kwekhalenda kwimithombo ye-bottleneck ukukhusela ixesha labo lokusebenza eligxilileyo. Kubonakala ngathi kucinywa isibane esiluhlaza kwaye endaweni yaso ngedashboard yenqanaba lenkqubo elanda umkhondo we-throughput - ireyithi egqityiweyo, imveliso elungele umthengi iphuma kwinkqubo.

Ukuphakamisa uMnyanzelo: Nini kwaye njani uTyalo-mali

Emva kokuba uxhaphaze ngokupheleleyo kwaye wabeka phantsi kumnyanzelo wakho, usengadinga i-output engaphezulu. Oku kuxa uphakamisa - tyala imali ekwandiseni umthamo wesithintelo. Kodwa ukuphakama kufuneka kufike ekugqibeleni, kungekhona kuqala. Uninzi lwemibutho lutsiba ngokuthe ngqo ukuqesha abantu abaninzi okanye ukuthenga izixhobo ezingaphezulu ngaphandle kokuqinisekisa kuqala ukuba umqobo okhoyo usetyenziswa ngokufanelekileyo. UGoldratt uqikelele ukuba uninzi lwezithintelo zisebenza kuphela50-60% yamandla abo anokubakhongenxa yokuphazamiseka, iintlanganiso ezingeyomfuneko, ukulungiswa kwakhona kwimiba yomgangatho ophezulu, kunye nexesha elichithwe kwimisebenzi engathinteliyo.

Phambi kokuba uqeshe omnye umlawuli oyilayo, buza: Lingakanani ixesha labo langoku elichithwe kwiintlanganiso zesimo ezinokuthatyathelwa indawo luhlaziyo olungahambelaniyo? Kungakanani ukuphinda kusetyenzwe kwakhona okuvela kwiincwadana ezingacacanga ezinokuthi zenziwe itemplate? Mingaphi imijikelo yokuphonononga efunekayo ngenxa yokuba abaqulunqi beswele umxholo onokubonelelwa kwangaphambili kwindlela yokusebenza eyakhiweyo? Amaqonga abeka kumbindi wemisebenzi yeshishini - ukudibanisa inkcazo yeprojekthi, ukuqhutywa komsebenzi okuvunyiweyo, unxibelelwano lwabathengi, kunye nolawulo lomsebenzi kwi-interface eyodwa - kaninzi unokuvula i-30-40% yesakhono esisebenzayo ngakumbi kwimithombo ye-bottleneck ekhoyo ngokususa ukungqubuzana kokutshintshwa kwesixhobo kunye nokuzingela ulwazi kuzo zonke izicelo ezivaliweyo.

Xa ukuphakama kuyimfuneko ngokwenene, tyala imali ngotyando. Yongeza umthamo kwisithintelo kwaye kuphela kwisithintelo. Ukongeza umthamo kwizinto ezingezizo i-bottleneck - ithuku lokukhanya okuluhlaza okwesibhakabhaka - ukuhambisa ngokulula uluhlu lwempahla olugqithisiweyo kumgca ophambi komqobo ofanayo, okwenza ingxaki ibe mandundu ngelixa inyusa iindleko.

Ukwakha i-Blue-Light-Free yeNkcubeko yokuSebenza

Ukuphelisa ukukhanya okuluhlaza okwesibhakabhaka ekugqibeleni kungumngeni wobunkokeli, hayi ubuchwephesha. Ifuna iinkokeli ezinokunyamezela ukubona amalungu eqela ngexesha elingacwangciswanga kwaye litolike njengophawu lwenkqubo elungeleleneyo kunokusilela kolawulo. Ifuna iimetrics ezivuza ukugqiba kunye nokunciphisa ixesha elikhokelayo kunokuxakeka komntu ngamnye. Kwaye ifuna ukubonakala komsebenzi okuvumela abathathi-zigqibo babone yonke inkqubo, hayi nje amanani asetyenziswa lisebe labo.

1. Buyisela usetyenziso lweemetrics nge-throughput metrics. Linganisa ukuhanjiswa okugqityiweyo ngeveki, umndilili wexesha elikhokeleyo ukusuka kwisicelo ukuya kuhambiso, kunye nesantya sokugqiba ngexesha kuneeyure ezisetyenziweyo okanye imisebenzi eqalwayo.
2. Yenza imigca ibonakale. Sebenzisa iidashbhodi ezibonisa umsebenzi oqhubekayo kwinqanaba ngalinye. Xa imigca ikhula kwinqanaba elithile, luphawu lwakho lothintelo olo — ayilulo uphawu lokuba imithombo yomlambo kufuneka ityhale ngamandla.
3. Seta imida ye-WIP. Faka inani lezinto ezinokuqhubeka kwinqanaba ngalinye. Xa i-cap ifikelelwe, izixhobo eziphuma phezulu ziyayeka ukuqala umsebenzi omtsha kwaye endaweni yoko zincede ukucima umqobo okanye ukwenza ugcino, uqeqesho, okanye imisebenzi yokuphucula.
4. Khusela isithintelo. Qinisekisa ukuba isixhobo sakho se-bottleneck asize silinde igalelo, soze siye kwiintlanganiso ezingeyomfuneko, kwaye soze sisebenze kwimisebenzi engabalulekanga. Yonke into efunwa ngumqobo kufuneka ifike ilungisiwe, igqityiwe kwaye ilungele ukusetyenzwa.
5. Bhiyozela ubuvila bobuchule. Xa ilungu leqela linomthamo okhoyo ngenxa yokuba inkqubo ilungelelene, yiqonde njengophawu lolawulo lwemisebenzi eqolileyo - kwaye usebenzise elo xesha ekuphuhliseni izakhono, ukuphuculwa kwenkqubo, okanye ukwenza izinto ezintsha endaweni yokwenza umsebenzi.

Ukukhanya okuluhlaza okwesibhakabhaka kumgangatho wefektri ngo-2007 yayiluphawu nje lwenkolelo enzulu: ukuba imveliso ilingana nomsebenzi. ITheory of Constraints kaGoldratt yangqina, ngokuchaneka kwezibalo, ukuba le nkolelo ayilunganga nje - iyatshabalalisa. Amashishini aqhuba kakuhle kakhulu abo bakhuphisana nabo kule minyaka ilishumi izayo ayizukuba ngawo apho wonke umntu nayo yonke inkqubo iqhuba ngokusetyenziswa okuphezulu. Iza kuba ngabo baqondayo apho kuhlala khona umqobo wabo wokwenyani, bawukhusele ngokungenalusini, kwaye babe nesibindi sokuvumela yonke enye into ukuba iphefumle.

Imibuzo Ebuzwa Rhoqo

Yintoni iTheory of Constraints kwaye ibali elithi "Blue Light" liyibonisa njani?

ITheory of Constraints (TOC) yifilosofi yolawulo echonga owona mqobo mkhulu othintela ukuphuma kwenkqubo. Ibali elithi "Blue Light" libonisa indlela ukutyhala umatshini ngamnye kwi-100% yokusetyenziswa okunene kutshabalalisa ukusebenza. Ngokugxila ekugcineni yonke into ixakeke kunokuphucula ukuhamba ngokunyanzeliswa, umzi-mveliso waphinda kathathu amaxesha okukhokela kwaye wawa ngexesha lokuhanjiswa ukusuka kwi-92% ukuya kwi-61%.

Kutheni ukwandisa ukusetyenziswa kobutyebi kulimaza imveliso iyonke?

Xa isibonelelo ngasinye sisebenza ngokuzeleyo, uluhlu lwempahla olusaqhubayo luyafumba, ludale imigca eyandisa amaxesha okukhokela ngokumangalisayo. Izixhobo ezingezizo i-bottleneck zivelisa ngokukhawuleza kunokuba isithintelo sinokuqhuba, siphuphuma inkqubo ngomsebenzi ongagqitywanga. Imveliso eyinyani ivela ekubekeni phantsi zonke izixhobo ukuya kwisantya sesinyanzelo, hayi ekupheliseni ixesha elingasebenziyo kuzo zonke iindawo zokusebenza.

Amashishini angayichonga njani imiqobo yawo endaweni yokusukela imilinganiselo yosetyenziso?

Qala ngokwenza imephu yokuhamba komsebenzi wakho ukuya ekupheleni kwaye ujonge apho umsebenzi uhlala ufolele khona. Loo ndawo yomgca ngumqobo wakho. Amaqonga afana ne-Mewayz, i-OS ye-207-modyuli yeshishini eqala kwi-$ 19 / mo, nceda amaqela abone ukuhamba komsebenzi, ukulandelela iibhotile, kunye nokuzenzekelayo imisebenzi engathinteliyo ukuze abaphathi bagxininise kwiinzame zokuphucula apho ngokwenene bakhulise i-throughput kune-metrics engamampunge.

Ngawaphi amanyathelo asebenzayo anokuthathwa ngamaqela ukusebenzisa imigaqo ye-TOC namhlanje?

Kuqala, chonga isithintelo sakho. Okwesibini, yisebenzise ngokuqinisekisa ukuba ayihlali ingenzi nto. Okwesithathu, thoba yonke enye into kwisantya somqobo. Okwesine, phakamisa isithintelo ngokutyala imali kwisikhundla saso. Ekugqibeleni, phinda umjikelo njengoko kuvela imiqobo emitsha. Izixhobo eziku app.mewayz.com zinokunceda ukuzenzela amanyathelo okuthobela kwaye zijonge umqobo wokusebenza ngokuqhubekayo.
