(1) kev xaiv cov khoom siv. Muaj qee qhov teeb meem hauv kev xaiv cov khoom siv tshuaj, xws li kev xaiv los ntawm kev paub dhau los (tsis muaj kev suav tiag tiag, lossis kev suav cov ntaub ntawv tsis txaus), kev nrhiav kev nce qib tsis pom kev, thiab kev tshawb nrhiav cov ntaub ntawv lub cev tsis txaus, uas cuam tshuam loj heev rau kev siv tau thiab kev txuag nyiaj ntawm cov khoom siv.

(2) kev teeb tsa thiab kev cob qhia cov khoom siv. Thaum lub sijhawm teeb tsa cov khoom siv tshuaj, kev nce qib ntawm kev tsim kho feem ntau raug saib xyuas, tsis quav ntsej txog qhov zoo ntawm kev tsim kho, uas ua rau cov nqi kho khoom siv nce ntxiv rau lub sijhawm tom qab. Tsis tas li ntawd, kev cob qhia tsis txaus rau cov neeg ua haujlwm kho khoom siv thiab kev ua haujlwm kuj ua rau muaj kev pheej hmoo rau kev tswj hwm thiab kev saib xyuas cov khoom siv tshuaj.

(3) kev nqis peev tsis txaus rau kev tswj hwm thiab kev saib xyuas ntawm cov ntaub ntawv xov xwm. Niaj hnub no, txawm hais tias ntau lub tuam txhab muab qhov tseem ceeb rau kev tswj hwm cov khoom siv thiab kev saib xyuas, nrog rau kev tswj hwm cov ntaub ntawv saib xyuas cov khoom siv thiab sau cov yam ntxwv yooj yim thiab ua qee yam, tab sis qee qhov teeb meem tseem muaj, xws li nyuaj rau muab cov ntaub ntawv saib xyuas txuas ntxiv, tsis muaj cov ntaub ntawv qhia txog cov khoom siv tshuaj zoo, xws li cov lus qhia, cov duab kos, thiab lwm yam, qhov no tsis pom kev ua rau muaj kev nyuaj ntawm kev tswj hwm cov khoom siv, kev saib xyuas thiab kev tsim kho dua tshiab.

(4) kev tswj hwm. Tsis muaj kev tswj hwm zoo thiab cov txheej txheem, ua rau kev tswj hwm cov neeg ua haujlwm saib xyuas cov khoom siv tshuaj tsis txaus, cov neeg ua haujlwm saib xyuas tsis muaj tus qauv, kev tswj hwm cov khoom siv tshuaj thiab cov txheej txheem saib xyuas ua rau muaj kev nyab xeeb zais cia.
