Qhov sib txawv tseem ceeb ntawm kev ua lag luam thiab cov kev xav tau ua haujlwm yog tias cov kev xav tau ntawm kev lag luam txhais cov hom phiaj kev lag luam thaum cov kev cai ua haujlwm txhais cov kev ua haujlwm ntawm qhov system.
Kev xav tau yog qhov tseem ceeb ntawm software vim tias tag nrho cov software yog raws li lawv. Thawj kauj ruam ntawm kev txhim kho software yog qhov yuav tsum tau sib sau ua ke thiab tshuaj xyuas. Muaj ob hom kev xav tau uas yog, kev ua lag luam thiab kev ua haujlwm. Cov kev xav tau ntawm kev lag luam tsom rau kev lag luam kev pom thaum lub luag haujlwm xav tau tsom mus rau qhov kev xav ntawm qhov system.
Yuav tsum tau ua lag luam yog dab tsi?
Kev xav tau kev lag luam muab cov peev txheej, kev xav tau kev lag luam, lossis cov teeb meem uas yuav tsum tau daws los ntawm ib qho haujlwm tshwj xeeb lossis ib qhov project. Ntxiv mus, nws yuav tsum tau meej thiab txhais tau zoo. Tsis tas li ntawd, ib lub hom phiaj tseem ceeb ntawm ib lub koom haum yog txhawb nqa lawv cov kev pabcuam. Yog li ntawd, tej zaum yuav muaj qhov yuav tsum tau ua kom muaj kev sib tw kom muaj kev paub ntau ntxiv. Thiab qhov no dhau los ua ib feem ntawm kev ua lag luam.
Nws yog qhov tsim nyog kom nkag siab txog kev xav tau ntawm kev lag luam, lub hom phiaj, cov ntaub ntawv hauv lub koom haum kom meej meej los txhais cov kev xav tau ntawm kev lag luam. Cov kev cai no muab cov ntaub ntawv los xyuas kom meej tias qhov project ua tiav cov hom phiaj raug txheeb xyuas. Cov kev xav tau ntawm kev lag luam tuaj yeem cuam tshuam nrog kev lag luam feem ntau lossis tsom mus rau cov koom nrog, pab pawg, cov neeg siv khoom, cov neeg ua haujlwm lossis lwm yam.
Cov Kev Xav Tau Ua Haujlwm yog dab tsi?
Cov kev xav tau ua haujlwm txhais cov haujlwm ua haujlwm ntawm software. Cov kev cai no txawv ntawm ib qho mus rau lwm qhov. Lawv piav qhia txog kev ua haujlwm ntawm qhov system thiab subsystems. Piv txwv li, kev ua haujlwm ntawm lub tsev qiv ntawv kev tswj hwm yog txawv ntawm lub tsev kho mob tswj hwm.
Ib lub tsev qiv ntawv tswj hwm yuav tsum ntxiv, hloov kho, tshem tawm cov tswv cuab cov ntsiab lus. Nws yuav tsum ntxiv, kho thiab tshem tawm cov ntsiab lus ntawm phau ntawv. Tsis tas li ntawd, nws yuav tsum qhia tus nqi them rov qab lig. Lub kaw lus tswj hwm tsev qiv ntawv yuav tsum saib cov tswv cuab cov ntsiab lus thiab cov ntsiab lus ntawm phau ntawv. Cov no yog qee qhov kev xav tau ntawm lub tsev qiv ntawv kev tswj hwm. Lub tsev kho mob kev tswj hwm yuav tsum ntxiv, hloov kho, tshem tawm cov neeg mob thiab tus kws kho mob cov ntsiab lus. Nws yuav tsum teem sijhawm, rov teem dua thiab tshem tawm cov sijhawm teem tseg. Nws yuav tsum tsim cov nqi. Cov no yog qee qhov kev xav tau ntawm lub tsev kho mob tswj hwm.
Qhov txawv ntawm Kev Lag Luam Kev Lag Luam thiab Kev Ua Haujlwm Zoo Li Cas?
Kev Yuav Tsum Ua Lag Luam vs Kev Ua Haujlwm Ua Haujlwm |
|
| Kev Yuav Tsum Ua Lag Luam yog cov kev xav tau uas txhais lub hom phiaj kev lag luam, lub zeem muag, thiab lub hom phiaj. | Cov Kev Xav Tau Ua Haujlwm yog qhov yuav tsum tau txhais cov haujlwm ntawm lub kaw lus lossis nws cov subsystems. |
| Lub ntsiab tseem ceeb | |
| Tsom rau kev pom kev lag luam. | Tsom rau qhov kev pom qhov system. |
| yam ntxwv | |
| kev lag luam yuav tsum dav thiab qib siab. | Cov kev xav tau ua haujlwm yuav tsum yog qhov tshwj xeeb thiab ntxaws. |
| Pab txheeb xyuas lub hom phiaj ua lag luam. | Pab txheeb xyuas cov haujlwm ntawm lub system. |
Summary – Kev Yuav Tsum Ua Lag Luam vs Cov Kev Xav Tau Ua Haujlwm
Kab lus no tau tham txog qhov sib txawv ntawm ob hom kev xav tau uas yog kev lag luam thiab kev ua haujlwm. Qhov sib txawv ntawm kev ua lag luam thiab cov kev xav tau ntawm kev ua haujlwm yog qhov kev xav tau ntawm kev lag luam txhais cov hom phiaj kev lag luam thaum cov kev cai ua haujlwm txhais cov kev ua haujlwm ntawm qhov system.
