Cov yam ntxwv zoo ntawm cov khoom siv maus taus yog txiav txim siab los ntawm cov kev qhia tshwj xeeb, cov yam ntxwv, thiab kev tsim kho ntawm cov khoom, thiab cuam tshuam rau kev siv ntawm cov khoom. Nws yog cov kev qhia tshwj xeeb thiab cov ntaub ntawv xa tawm los ntawm kev tsim qauv rau cov txheej txheem, kev tsim khoom, thiab kev sim, suav nrog qhov ntev, kev txwv thiab kev ua siab ntev, kev ua haujlwm, kev pabcuam lub neej, kev sib hloov, kev ua qias tuaj, kev nyab xeeb ntawm lub neej, thiab kev ua raws li tsoomfwv cov cai thiab cov qauv.
Kev ntsuas qhov tseem ceeb ntawm cov khoom seem yog nyob ntawm theem ntawm qhov project tseem ceeb ntawm cov khoom seem, thiab muab faib ua qhov tseem ceeb, qhov tseem ceeb, thiab qhov dav dav. Cov cim theem yog sawv cev los ntawm A, B, thiab C.
Qhov tseem ceeb ntawm qib A: Yog tias ib lossis ntau yam khoom hauv cov khoom seem tau mus txog qib A qhov tseem ceeb, cov khoom seem yog suav tias yog cov khoom tseem ceeb. B-theem thiab C-theem khoom raug tso cai nyob rau hauv A-theem khoom seem.
Cov khoom tseem ceeb theem B: Ib lossis ntau yam khoom hauv cov khoom seem muaj qhov tseem ceeb ntawm qib B, tab sis tsis muaj cov khoom qib A tuaj yeem suav tias yog cov khoom tseem ceeb. C-theem khoom raug tso cai nyob rau hauv B-theem spare qhov chaw.
Chav Kawm C dav dav: Cov khoom uas tsis muaj Class A thiab Class B cov khoom hauv cov npe khoom seem thiab muaj kev cuam tshuam me ntsis rau kev ua haujlwm thiab kev pabcuam lub neej ntawm cov khoom, uas yuav tsis ua rau muaj kev tsis txaus siab los ntawm cov neeg siv khoom lossis ib tus neeg. Cov khoom A-theem thiab B-theem tsis raug tso cai hauv C-theem khoom seem.
