Umnyango we-IT we-VTB izikhathi eziningana kwadingeka ubhekane nezimo eziphuthumayo ekusebenzeni kwezinhlelo, lapho umthwalo kuwo ukhuphuka izikhathi eziningi. Ngakho-ke, bekunesidingo sokuthuthukisa nokuhlola imodeli ezobikezela inani eliphakeme kumasistimu abalulekile. Ukuze wenze lokhu, ochwepheshe be-IT bebhange bamise ukuqapha, bahlaziye idatha futhi bafunde ukwenza izibikezelo ngokuzenzakalelayo. Sizokutshela esihlokweni esifushane ukuthi yimaphi amathuluzi asize ukubikezela umthwalo kanye nokuthi asizile yini ukuthuthukisa umsebenzi.
Izinkinga ngezinsizakalo zomthwalo omkhulu ziphakama cishe kuzo zonke izimboni, kodwa emkhakheni wezezimali zibalulekile. Ngehora le-X, wonke amayunithi okulwa kufanele alungele, ngakho-ke kwakudingeka ukwazi kusengaphambili ukuthi yini engenzeka futhi ngisho nokunquma usuku lapho umthwalo uzogxuma futhi yiziphi izinhlelo ezizobhekana nazo. Ukwehluleka kudingeka kubhekwane nakho futhi kuvinjwe, ngakho isidingo sokusebenzisa uhlelo lokuhlaziya olubikezelayo asizange kuxoxwe ngaso. Bekudingeka ukwenza izinhlelo zibe zesimanje ngokusekelwe kudatha yokuqapha.
Izibalo ngamadolo akho
Iphrojekthi ye-payroll ingenye yezinto ezibucayi kakhulu uma kwenzeka ukwehluleka. Iqondakala kakhulu ekubikezelweni, ngakho-ke sinqume ukuqala ngayo. Ngenxa yokuxhumana okuphezulu, amanye amasistimu angaphansi, okuhlanganisa nezinsiza zebhange ezikude (RBS), angaba nezinkinga ngezikhathi zomthwalo omkhulu. Isibonelo, amaklayenti ayejabule nge-SMS mayelana nokuthola imali aqala ukuyisebenzisa ngenkuthalo. Umthwalo ungagxuma ngaphezu kokuhleleka kobukhulu.
Imodeli yokuqala yesibikezelo sakhiwe mathupha. Sithathe okulayishiwe konyaka odlule futhi sabala ukuthi yiziphi izinsuku okulindeleke ukuthi kufike kuzo amanani aphezulu: isibonelo, ngomhla ka-1, 15 no-25, kanye nezinsuku zokugcina zenyanga. Le modeli idinga izindleko ezinkulu zomsebenzi futhi ayizange inikeze isibikezelo esinembile. Noma kunjalo, ibone izingqinamba lapho kudingekile khona ukwengeza ihadiwe, futhi yenza kwaba nokwenzeka ukukhulisa inqubo yokudlulisa imali ngokuvumelana namaklayenti e-anchor: ukuze kunganiki amaholo nge-gulp eyodwa, ukuthengiselana okuvela ezifundeni ezahlukene kwahlukaniswa ngokuhamba kwesikhathi. Manje sesiwacubungula ezingxenyeni lapho ingqalasizinda ye-IT yebhange "ingakwazi ukuhlafuna" ngaphandle kokwehluleka.
Ngemva kokuthola umphumela wokuqala omuhle, sadlulela ekubikezeleni okuzenzakalelayo. Izindawo ezibaluleke kakhulu eziyishumi nambili bezilinde ithuba lazo.
Indlela eyinkimbinkimbi
I-VTB iqalise uhlelo lokuqapha oluvela ku-MicroFocus. Ukusuka lapho sathatha ukuqoqwa kwedatha ukuze kubikezelwe, isistimu yokugcina kanye nesistimu yokubika. Eqinisweni, ukuqapha kwase kusendaweni, okwakusele nje ukwengeza amamethrikhi, imojula yokubikezela nokudala imibiko emisha. Lesi sinqumo sisekelwa usonkontileka wangaphandle i-Technoserv, ngakho-ke umsebenzi oyinhloko wokusebenzisa iphrojekthi wawela kochwepheshe bayo, kodwa sazakhela imodeli ngokwethu. Uhlelo lokubikezela lwenziwa ngokususelwa kuMprofethi, umkhiqizo womthombo ovulekile owakhiwe yi-Facebook. Kulula ukuyisebenzisa futhi ihlanganisa kalula namathuluzi ethu okuqapha ahlanganisiwe afakiwe kanye ne-Vertica. Uma sikhuluma nje, isistimu ihlaziya igrafu yokulayisha bese iyikhipha ngokususelwe ochungechungeni lwe-Fourier. Kungenzeka futhi ukwengeza ama-coefficients athile emini, athathwe kumodeli yethu. Amamethrikhi athathwa ngaphandle kokungenelela komuntu, isibikezelo sibalwa kabusha ngokuzenzakalelayo kanye ngeviki, futhi imibiko emisha ithunyelwa kubamukeli.
Le ndlela ihlonza imijikelezo eyinhloko, isibonelo, ngonyaka, ngenyanga, ngekota nangeviki. Izinkokhelo zamaholo nentuthuko, izikhathi zamaholide, amaholide nokuthengisa - konke lokhu kuthinta inombolo yezingcingo eziya kumasistimu. Kuvele, ngokwesibonelo, ukuthi eminye imijikelezo idlulana, kanti umthwalo omkhulu (75%) ezinhlelweni uvela eSifundazweni Esimaphakathi. Izinkampani ezisemthethweni nabantu ngabanye baziphatha ngendlela ehlukile. Uma umthwalo ovela "ochwepheshe befiziksi" usatshalaliswa ngokulinganayo phakathi nezinsuku zeviki (lokhu kuthengiselana okuningi okuncane), khona-ke ezinkampanini i-99,9% isetshenziswa emahoreni okusebenza, futhi ukuthengiselana kungaba kufushane, noma kungacutshungulwa phakathi nesikhathi esithile. imizuzu noma amahora.
Ngokusekelwe kudatha etholiwe, amathrendi esikhathi eside ayanqunywa. Uhlelo olusha seluveze ukuthi abantu bathutheleka ngobuningi babo beya ezinsizeni zamabhange ezikude. Wonke umuntu uyakwazi lokhu, kodwa besingalindele isilinganiso esinjalo futhi ekuqaleni asizange sikholelwe kuso: inani lezingcingo eziya emahhovisi asebhange liyancipha ngokushesha okukhulu, futhi inani lemisebenzi ekude likhula ngenani elifanayo ncamashi. Ngokunjalo, umthwalo kumasistimu nawo uyakhula futhi uzoqhubeka nokukhula. Manje sibikezela umthwalo kuze kube nguFebhuwari 2020. Izinsuku ezijwayelekile zingabikezelwa ngephutha elingu-3%, nezinsuku eziphakeme ngephutha lika-10%. Lona umphumela omuhle.
izingibe
Njengenjwayelo, lokhu akuzange kube ngaphandle kobunzima. Indlela ye-extrapolation esebenzisa uchungechunge lwe-Fourier aweqeli uziro kahle - siyazi ukuthi amabhizinisi asemthethweni enza imisebenzi embalwa ngezimpelasonto, kodwa imojula yokubikezela ikhiqiza amanani akude kakhulu kunoziro. Kwakungenzeka ukuwalungisa ngenkani, kodwa izinduku akuzona indlela yethu. Ngaphezu kwalokho, kwakudingeka sixazulule inkinga yokubuyisa idatha ngokungenabuhlungu kumasistimu omthombo. Ukuqoqwa okujwayelekile kolwazi kudinga izinsiza zekhompuyutha ezibucayi, ngakho-ke sakhe inqolobane esheshayo sisebenzisa ukuphindaphinda futhi samukele idatha yebhizinisi evela kumakhophi. Ukungabikho komthwalo owengeziwe ezinhlelweni eziyinhloko ezimweni ezinjalo kuyisidingo sokuvimbela.
Izinselele ezintsha
Umsebenzi oqondile wokubikezela iziqongo eziphakeme waxazululwa: akuzange kube khona ukwehluleka okuhlobene nokugcwala ngokweqile ebhange kusukela ngoMeyi walo nyaka, futhi uhlelo olusha lokubikezela ludlale indima ebalulekile kulokhu. Yebo, kwavela ukuthi akwanele, futhi manje ibhange lifuna ukuqonda ukuthi iziqongo ziyingozi kangakanani kulo. Sidinga ukuqagela sisebenzisa amamethrikhi avela ekuhlolweni komthwalo, futhi cishe u-30% wamasistimu abalulekile lokhu sekuvele kusebenza, amanye asezinhlelweni zokuthola izibikezelo. Esigabeni esilandelayo, sizobikezela umthwalo wezinhlelo hhayi ekuhwebeni kwebhizinisi, kodwa ngokwengqalasizinda ye-IT, okungukuthi sizokwehla ungqimba olulodwa. Ngaphezu kwalokho, sidinga ukwenza ngokuzenzakalelayo ngokugcwele ukuqoqwa kwamamethrikhi kanye nokwakhiwa kwezibikezelo ngokusekelwe kuzo, ukuze singabhekani nokulandiwe. Akukho lutho oluhle ngakho - seqa nje ukuhlola nokulayisha ngokuhambisana nezinqubo ezihamba phambili zomhlaba.
