Umfutho wokubhala lo mdwebo kwakuyindatshana . Ngiphinde ngathola isihloko esishicilelwe eminyakeni engu-4 edlule sithakazelisa - .
Kwakubonakala kuthakazelisa ukuthi umcabango ofanayo - "sebenzisa ingqondo yebhizinisi kusizindalwazi".
Akumina kuphela owafika engqondweni.
Futhi, esikhathini esizayo, ngangifuna ukuzigcinela, okokuqala, intuthuko ethakazelisayo eyavela ngesikhathi sokuqaliswa. Ikakhulukazi uma kucatshangelwa ukuthi muva nje kuthathwe isinqumo esinamasu sokushintsha izakhiwo nokudlulisa umqondo webhizinisi ezingeni elingemuva. Ukuze konke okuthuthukisiwe kuzobe kungasasizi muntu futhi ngeke kuthakasele muntu.
Izindlela ezichaziwe azilona uhlobo oluthile lokutholwa noma oluhlukile. wazi kanjani, yonke into ingeyakudala futhi isetshenziswe izikhathi ezimbalwa (ngokwesibonelo, ngasebenzisa indlela efanayo eminyakeni engu-20 edlule ku-Oracle) Ngisanda kunquma ukuqoqa yonke into endaweni eyodwa. Uma kwenzeka isiza othile. Njengoba umkhuba ubonisile, ngokuvamile umqondo ofanayo ufika kubantu abahlukene ngokuzimela. Futhi kuyasiza ukuzigcinela yona njengesikhumbuzo.
Yiqiniso, akukho lutho oluphelele kulo mhlaba, amaphutha kanye ne-typos ngeshwa kungenzeka. Ukugxeka nokuphawula kwamukelwa kakhulu futhi kulindelekile. Futhi omunye umniningwane omncane - imininingwane ethile yokusetshenziswa ayifakiwe. Noma kunjalo, yonke into isasetshenziswa kuphrojekthi yangempela yokusebenza. Ngakho-ke, lesi sihloko siwumdwebo nje kanye nencazelo yomqondo ojwayelekile, akukho okunye. Ngethemba ukuthi kunemininingwane eyanele yokuqonda isithombe sisonke.
Umbono ojwayelekile uthi “hlukanisa futhi unqobe, fihla futhi uphathe”
Umbono ungowakudala - i-schema ehlukile yamatafula, i-schema ehlukile yemisebenzi egciniwe.
Iklayenti alikwazi ukufinyelela idatha ngokuqondile. Konke iklayenti elingakwenza ukushayela umsebenzi ogciniwe futhi licubungule impendulo eyamukelwe.
