Software xav tau tsim kom muaj kev pom zoo ntawm koj pab neeg thiab cov neeg siv khoom ntawm daim ntawv thov yuav tsum ua. Tsis muaj cov lus piav qhia ntawm cov yam ntxwv dab tsi yuav suav nrog thiab cov ntsiab lus ntawm yuav ua li cas cov yam ntxwv yuav ua haujlwm, cov neeg siv ntawm software tsis tuaj yeem txiav txim siab yog tias software yuav ua tau raws li lawv cov kev xav tau.

Tsuas yog li ntawd, vim li cas cov kev xav tau xav tau?

Cov kev xav tau muaj tus cwj pwm, cwj pwm thiab cov khoom ntawm lub neej yav tom ntej. Yog li ntawd, lub ntsiab hauj lwm ntawm lub kev xav tau yog los xyuas kom meej tias lawv tau nkag siab los ntawm txhua tus neeg muaj feem cuam tshuam. Kev ua haujlwm nrog kev xav tau koom nrog ntau yam txheej txheem, e.g. kev txheeb xyuas, txheeb xyuas, txheeb xyuas thiab, thaum kawg, kev tswj hwm.

Tsis tas li ntawd, vim li cas kev tswj xyuas cov cai tseem ceeb? Kev tswj cov kev xav tau pab cov neeg muag khoom thiab cov neeg siv khoom nkag siab thiab pom zoo yam xav tau thiab tsis txhob nkim sijhawm, peev txheej, thiab kev siv zog. Kev tswj cov kev xav tau pab kom ua tiav qhov project los ntawm kev zam kom tsis txhob muaj cov laj thawj saum toj kawg nkaus rau qhov project tsis ua haujlwm: pluag kev xav tau ntes, scope creep, tsis pom zoo txog kev lees txais.

Yog li ntawd, vim li cas qhov kev xav tau yog qhov tseem ceeb hauv kev txhim kho software?

Kev soj ntsuam xav tau yog qhov tseem ceeb rau kev ua tiav lossis tsis ua haujlwm ntawm lub tshuab lossis software qhov project. Cov kev xav tau yuav tsum tau sau tseg, ua tau zoo, ntsuas tau, kuaj tau, traceable, muaj feem xyuam rau cov kev xav tau kev lag luam lossis cov hauv kev, thiab txhais tau rau ib theem ntawm kev nthuav dav txaus rau kev tsim qauv.

Dab tsi yog hom kev xav tau?

Cov kev xav tau , uas feem ntau xav txog, tau muab faib ua peb pawg, uas yog, ua haujlwm kev xav tau , tsis ua haujlwm kev xav tau , thiab domain kev xav tau . IEEE txhais tau tias ua haujlwm kev xav tau raws li 'kev ua haujlwm uas lub kaw lus lossis cov khoom siv yuav tsum muaj peev xwm ua tau.
