Cov tsis yog - kev xav tau (NFRs) txhais cov yam ntxwv xws li muaj, kev tswj xyuas, kev ua tau zoo, kev ntseeg tau, kev ua kom muaj zog, kev ruaj ntseg, thiab kev siv tau.

Ntawm no, cov piv txwv ntawm cov kev cai tsis ua haujlwm yog dab tsi?

Qee qhov kev xav tau uas tsis ua haujlwm yog:

  • Kev ua tau zoo - piv txwv li Lub Sijhawm Teb, Kev Tshaj Tawm, Kev Siv, Static Volumetric.
  • Scalability.
  • Muaj peev xwm.
  • Muaj.
  • Kev ntseeg tau.
  • Rov qab tau.
  • Kev ruaj ntseg.
  • Kev pabcuam.

Ib yam li ntawd, dab tsi yog usability nyob rau hauv cov kev cai uas tsis haumxeeb? Cov kev xav tau tsis ua haujlwm (NFRs) txhais cov txheej txheem xws li kev ruaj ntseg, kev cia siab, kev ua tau zoo, kev tswj xyuas, kev ua kom muaj peev xwm, thiab kev siv tau . Lawv ua hauj lwm asconstraints los yog txwv nyob rau hauv lub tsim ntawm lub system nyob rau hauv lub sib txawv backlogs. Lawv xyuas cov kev siv tau andeffectiveness ntawm tag nrho cov system.

Ntxiv rau qhov no, dab tsi yog cov kev cai uas tsis ua haujlwm?

Hauv systems engineering thiab kev xav tau engineering, ib tsis yog - kev xav tau kev ua haujlwm (NFR) yog a kev xav tau uas qhia meej txog cov txheej txheem uas tuaj yeem siv los txiav txim rau kev ua haujlwm ntawm ib qho system, es tsis yog tus cwj pwm tshwj xeeb. Lawv tau sib piv nrog kev xav tau uas txhais cov cwj pwm tshwj xeeb lossis kev ua haujlwm.

Leej twg txhais cov kev cai tsis ua haujlwm?

Cov kev xav tau tsis ua haujlwm . NonfunctionalRequirements (NFRs) txhais system attributes xws li kev ruaj ntseg, kev cia siab, kev ua tau zoo, kev ruaj ntseg, scalability, thiab usability. Lawv ua haujlwm raws li kev txwv lossis kev txwv ntawm kev tsim qauv ntawm lub kaw lus hla ntawm qhov sib txawv backlogs.
