Software Kuvandudza Maitiro

Mune ino posvo isu tichaenda kuburikidza dzakasiyana dzakasiyana software yekuvandudza nzira pamwe nezvakanakira nekuipira uye nguva yekushandisa imwe modhi.

Iterative Muenzaniso

Iyo iterative yehupenyu kutenderera modhi haiyedze kutanga neiyo yakazara kududzirwa kwezvinodiwa. Panzvimbo iyoyo, kuvandudza kunotanga nekutsanangudza nekushandisa chete chikamu che software, iyo inogona kuongororwa kuitira kuti ione zvimwe zvinodiwa. Maitiro aya anozodzokororwa, achiburitsa vhezheni nyowani yesoftware yeimwe neimwe kutenderera kweiyo modhi.

Funga nezve iterative hupenyu hwekutenderera modhi iyo inove nekudzokorora anotevera mana zvikamu mukuteedzana:

Chikamu Chinodiwa, mune izvo zvinodiwa zve software zvinounganidzwa uye kuongororwa. Iteration inofanira kupedzisira yaguma nechinodiwa chikamu chinoburitsa yakazara uye yekupedzisira kutaurwa kwezvinodiwa.

Chikamu chekugadzira, mune iyo software mhinduro yekusangana nezvinodiwa zvakagadzirwa. Izvi zvinogona kuve dhizaini nyowani, kana kuwedzeredzwa kweakambogadzirwa.

Chikamu cheKushandisa uye Bvunzo, apo software yacho yakanyorwa, yakabatanidzwa uye yakaedzwa.



Chikamu chekudzokorora, mune iyo software inoongororwa, izvo zvazvino zvinodiwa zvinoongororwa, uye shanduko uye zvinowedzerwa kune zvinodikanwa zvakatsanangurwa.

Kune yega yega kutenderera kweiyo modhi, sarudzo inofanirwa kuitwa yekuti software yakaburitswa neyakafambiswa icharaswa here, kana kuchengetwa senzvimbo yekutangira yeanotevera kutenderera (dzimwe nguva inonzi inowedzera kuwedzera prototyping.

Pakupedzisira poindi inosvikwa panodiwa zvakakwana uye software inogona kuunzwa, kana zvobva zvisingakwanise kusimudzira software sezviri kudikanwa, uye kutanga kutsva kunofanirwa kuitwa.

Iyo iterative hupenyu hwekutenderera modhi inogona kufananidzwa nekugadzira software neinoteedzana kufungidzira. Kudhirowa fananidzo nemasvomhu nzira dzinoshandisa dzakateedzana kufungidzira kusvika pamhedzisiro mhinduro, kubatsirwa kwenzira dzakadai kunoenderana nekukurumidza kwavanosangana pamhinduro.

Kiyi yekubudirira kushandiswa kweiyo iterative software yekuvandudza hupenyu kutenderera yakasimba kuvimbiswa kwezvinodiwa, uye kuongorora (kusanganisira kuyedzwa) kweimwe vhezheni yesoftware inopesana nezvinodiwa mukati mega kutenderera kwemuenzaniso.
